Building An Integrated Pest Management Plan – Part 5

By Phil Gibson

This is the fifth in a series of articles designed to introduce an integrated pest management framework for cannabis cultivation facilities. To see Part One, an overview of the plan and pest identification, click here. For Part Two, on pest monitoring and record keeping, click here. For Part Three, on preventative measures, click here. For Part Four, control methods, click here. Our final chapter, Part Six, discussing emergency response, comes out next week to wrap it all up.

This is Part 5: Pest Control – Taking Action

Previous chapters have covered the many preparations you can take to protect your facilities from pest attacks and outbreaks before they get started. This chapter will summarize the concepts of pest control thresholds and the actions you can take for the painful event when you surpass those limits (and various examples). The Integrated Pest Management (IPM) recommendations provide you with a framework for these plans.

Figure 1: Cleaning regimen, the heart of successful operations – no biofilm buildups

Preventative actions are part of your regular site operations; in other words, they are how you avoid problems before they happen. Just to hit this action one more time: cleaning must be fundamental to your facility. Water sanitation and changing filters must be done on schedule and frequently to avoid biofilm build up and nasty self-multiplying eco-systems.

For each of the rooms in your facility, identify the acceptable tolerance level for each type of pest that you may encounter. Define the intervention levels per room: preventative, direct action and escalated direct action. Follow your predefined procedures and defend your facility. Let’s cover high, medium and low tolerance example responses.

High Threshold for Tolerance

For example, the impact on your plants, your profits and your yields from the discovery of a white fly fluttering inside of one of your flower rooms may be very small. If this presence is late in your harvest cycle, your tolerance of this discovery may be very high. Your team could take preventative actions to clean the room more aggressively or to check your traps more frequently, but you are probably not going to want to invest in aggressive actions at that time in the harvest cycle.

Move from passive observation to the shake test. With sticky traps in place, shake or brush your plants. Do you see the bug counts increase on your test sheets?

Figure 2: Thrip Evidence c/o UC ANR Publication 7429

As that infestation grows, you may set a threshold for direct action (i.e. 5-10 flies per trap per week). If you reach that level, implement a treatment action with a non-chemical microbial biofungicide to stop growth in the roots or neem oil as a direct chemical action.

When you reach your escalated threshold of 10-20 flies per trap or direct plant damage is apparent, an infestation is more serious. In that event, you may choose to take steps to directly reduce the pest population with knock down sprays of approved direct chemical pesticides like citric acid or insecticidal soaps. Be sure to use your Personal Protective Equipment (PPE) for breathing and contact safety if you get into this situation.

Medium Threshold for Tolerance

Depending on the timing in your harvest cycle, the discovery of fungus gnats in your grow room may trigger a medium level alarm for you. Is the location, a small example with a minimal frequency? Is this addressable with additional attention to cleaning the area and longer dry periods in the irrigation or is this the beginnings of an infestation? Fungus gnats feed off of fungus or organic matter in soil triggered from an overly moist root environment. You may choose to react with immediate cleaning at the first existence in a room. Or you could set your “Medium” level alert status to be additional sticky trap distribution at the first visible gnat. If those counts reach 10-20 gnats per sticky trap per week, begin your foliar spray regimen with Zerotol or the equivalent.

If these counts do not respond to your treatment, meaning that the next sticky trap count reaches beyond 20+ gnats per trap or visible direct plant damage, then institute your root drench protocol with a solution of BActive 1-2 times per week until the problem is under control and the counts are reduced. If the growth continues, look to approved pesticides in your area (as an example, AzaGuard Asadirectin).

Low Threshold for Tolerance

Alternatively, you may have a unified air circulation system due to facility limitations. Your air circulation may be shared across all of your mother plants, clones, veg and flowering plant areas. In that case, any presence of an airborne fungal infection like powdery mildew would have a very low tolerance of acceptance. Selective de-leafing of the infection and increased airflow are your first defense. Any visible presence beyond that would trigger a low threshold alert and immediately start a preventative action, such as carefully removing the infected plant material much wider than a few leaves and treating the area with foliar sprays like Zerotol (hydrogen peroxide plus).

If the penetration continues or expands, treatment would escalate to minimal risk pesticide follow up and observation. Chemical oils or citric acid might be in your mix in this case.

Finally, if repetitive treatments once a week are not turning the tide, increasing to once per day or even once per ON/OFF lighting cycle until the infection is controlled. At this point, you may decide to strip the room down and start over. Clearly the choice to “throw in the towel” is a total loss of the crop, but it may be the best option relative to minimal yields and failed flowers that will not sell.

Pest Control Actions

Our Integrated Pest Management recommendations paper gives you examples of what to consider for plans with white flies, fungus gnats, root aphids, powdery mildew and biofilm on plumbing or surfaces. These follow the preventative action, direct action, escalated direct action and pesticide approaches for each example. These are options to plan for water sources, root treatment, tunneling, crawling and flying phases.

In summary this week

As covered, preventative measures are your best defense. Hire expert consultants and plan these well. Escalate your response based on your scouting activity and your plan. Add your sticky traps, de-leafing, root drench, foliar sprays or knock down sprays as defined by your pest population control actions document.

For more detail on each of these treatments, you can see examples for your integrated pest management procedures in our complete white paper for Integrated Pest Management Recommendations, download the document here.

In our final chapter, Emergency Response, we will review control thresholds and example plans for a range of problems from biofilm build up to white flies and more.

Our final chapter after will describe emergency response framework and reviewing your complete plans. See you next week.

Building An Integrated Pest Management Plan – Part 4

By Phil Gibson

No Comments

This is the fourth in a series of articles designed to introduce an integrated pest management framework for cannabis cultivation facilities. To see Part One, an overview of the plan and pest identification, click here. For Part Two, on pest monitoring and record keeping, click here. For Part Three, on preventative measures, click here. Part Five comes out next week on how to build a framework for control actions and how to monitor them. More to come!

This is Part 4: Direct Control Options

Even when the best methods are implemented and precautions are taken to protect your infrastructure, determined pests can penetrate your perimeter. Before you see crawling, hopping or flying insects, or sickly-looking plants, be sure to implement your physical protection (positive pressure airflow sealed facilities) and personal hygiene methods (shoe baths, sticky mats, & air shower entrances) to protect your crops. Equip your employees with personal protection equipment (PPE) proper gloves, masks and clothing as discussed in our last chapter, preventative measures.

When things do break-out beyond your acceptable thresholds, Direct Control Options include non-chemical microbial biofungicides, microbial bioinsecticides and direct chemical control options. Lots of big scary words there, all of which are toxic even under safe application methods and when used at recommended concentrations levels. This means training in their use and protective clothing is required. Careful application of these control options is necessary so you exterminate your pests and not your people! This seems obvious, but do not just “wing it.”

These chemical elements can be applied in diluted concentration levels, manual wipe-down application, concentrated flush frequencies, or root drench applications, foliar spray mist applications, HVAC aerial diffusions and aerial knock-down sprays. You may even choose to remove badly infected plants and destroy them completely.

Use experts when you are planning for these tools. All of these methods require handling and safety precautions. Proper breathing filters, eye & skin protection, as well as disposable gowns/hazmat suits should be used when applications are performed and until the applications have dissipated to safe levels. Be careful not to co-mingle removed plant materials. Gloves become transport and infection spreaders after use.

Please also be sure to review your harvest testing requirements and what treatments are safe for your consumers and within legal limits. No one wants to have their harvest rejected due to pesticide contamination.

Figure 2: Municipal Water Treatment, RAIR Cannabis, Michigan

Clean-up after application may be required depending on the bioinsecticide or chemical that is used. Again, always ensure the safety of your employees and take precautions.

Start the application of your control options with your site map, room assignments and scout monitoring teams. Where does air flow into and within the facility? When your scouting team count logs go beyond your acceptable thresholds, here are some options for you.

Let’s begin with cleaning your irrigation and nutrient water sources. For a walk-through tutorial for incoming water treatment, humidity recovery and nutrient water recycling, please review the video tour of Water Treatment at RAIR Cannabis to see how an expert has done it.

From the IPM Planning Guide standpoint, peroxide and acid sterilizers can be used to clear irrigation water, for surface wipe-downs or as direct plant applications. We will cover those first. Caustic sterilizers require PPE for cleaning. Forgive my image here, we were just using water.

Concentrated Cleaners for Surfaces & Irrigation Sources (Hydrogen Peroxide & Sanitizers)

Plant interacting interfaces, i.e. surfaces, benches, walls, floors, trays, utensils, clippers, etc. should be sterilized with every use. Methods can include direct wipe-down or scrub, concentrated or diluted sprays or room vaporizers. A good example of hydrogen peroxide (H2O2) liquid would be a food grade sanitizer with 3-35% H2O2 content. Use acceptable diluted versions of these cleaners as appropriate.

Figure 3: Cleaning & Scrubbing, Where’s the PPE?

A commercial example would be Zerotol 2.0 with 27% H2O2 & their proprietary acid mix. Alternatively, you can use direct hydrogen peroxide generators from commercial sources to generate your H2O2 at various concentrations. More detailed examples are included in the complete Integrated Pest Management Guide (link at the end of this article). Establish your procedures for sterilizing your rooms and tools before you introduce plants, and describe what is to be done after every harvest and room turn. Track the cleaning materials used for your operational records. You will find this useful to track operational cost over time.

Sanitizing Acids for Surfaces & Irrigation Sources

Similar to hydrogen peroxide, hypochlorous acid (HOCl) comes in many commercial forms and can also be generated onsite using purchased generators. Commercial mix examples are UC Roots, Watermax and Athena Cleanse. They come in 0.028% to 15% concentrations. Self-generators range in output from highly precise 0.01% to 1% concentrations with more examples in the guide.

Treatment Tools

OK, so enough on cleaning preparation. Here are some tools that can be used to fight back against a pest intrusion:

Non-Chemical Microbial Biofungicide for Pathogens in Soil or Fertigation Water

Microbial fungicides are available to clear nutrient irrigation systems by minimizing pathogens and improving plant resistance to infections. Some fungicide versions target root pathogens by attacking the diseases directly. Others control or suppress common water carried challenges like pythium, rhizoctonia, phytophthora, fusarium and others. Brand names include Botanicare, Bonide, BioWorks, Actinovate, Mycostop and many more. Details covered in the guide.

Non-Chemical Microbial Bioinsecticides for Larval Stages

These biological tools attack the organisms or insects at a physical or mechanical way by breaking down the pest’s nervous system, biochemistry, or structural integrity (exoskeletons, etc.). These are engineered or living organisms (bugs to attack bugs) that are developed as targeted attacks for specific pests. Brand names are BioCeres, Botanigard, Venerate, Bio Solutions and others.

Minimal Risk Chemical Pesticides for Airborne Critters

Figure 3: Example Fungus Gnat Infestation – Royal Queen Seeds blog

Regularly approved for used in most locales, essential oils, natural acids (like citric acid) and insecticidal soap are commonly available in every hydroponic store. These work very well as safe spray “knock-down” insecticides for crawling or flying pests. Commercial examples use a proprietary mix of various oils, citric acids or isopropyl alcohol to do their task (examples in guide). Insecticidal soaps and fungicides for surface cleaning perform a similar purpose and typically use potassium salts or fatty acid mixtures.

Biochemical Pesticides

These tools are used to inhibit insect or fungal growth to acceptable levels. The multifaceted and commonly used neem oil comes in many commercial versions and is a naturally occurring pesticide extracted from the leaves and seeds of the neem tree. Example brand names are Bonide, Monterey, Triact and others. They range in concentrations from 0.9% to 70% concentrations. These oils suffocate living organisms or eliminate moisture to kill insects, spores or fungus at their initiation and throughout their lifespan.

Another option here are Azadirachtins. These act as insect growth regulators and disrupt the bugs natural evolution. Brand names are AzaGuard, AzaMax and others in the guide.

In summary, this week

We summarized some of the many pest control options available for water treatment, soil borne, intermediate or flying pests. We also covered various concentrations for these pesticide and sterilizer options. If you are not familiar with dilution ratios, %, PPM terms and how to apply the correct level of pesticide, you may find our plant science test kitchen blog on this topic of use here.

Chemical access and use should be restricted to employees familiar with their authorized application. PPE is very important to protect any employee that will come in contact with materials, liquids or vapors for chemical resources (gloves, boots, respirators, Tyvek (or equivalent protective wear) suits and eye protection or goggles.

In our next chapter, Pest Population Control Actions, we will review control thresholds and example plans for a range of problems from biofilm build up to white flies and more. Our final chapter after that will suggest an emergency response framework and how to address pest outbreaks. See you next week.

Building An Integrated Pest Management Plan – Part 3

By Phil Gibson

No Comments

This is the third in a series of articles designed to introduce an integrated pest management framework for cannabis cultivation facilities. To see Part One, click here. For Part Two, click here. Part Four comes out next week and covers direct control options for pest reduction. More to come!

This is Part 3: Preventive Measures

Preventive measures are a great investment in the profitability of your operations. Our objective is to ensure successful repeat harvests forever. Build your procedures with this in mind. This means maintenance and regular review. We all realize that this work can be monotonous drudgery (we know!), but these procedures will ensure your success.

Figure 1: New Air Shower Access Installation

As a summary to begin, pest access must be limited wherever possible. Employees are the first place to start, but we must also return to our site map and review our facility design and workflows. Every operation has to move plants from nursery through harvest and post-harvest. Where should cleaning happen? Of course, you have to clean up post-harvest but when should this occur during the grow cycle? What is the best way to monitor and clean environmental management systems (i.e. air, water) and what are the weaknesses in the physical barriers between operations? Let’s walk through these issues one-by-one.

Employee Access and Sterile Equipment

Follow procedures to screen and protect your employees both to eliminate pests and to avoid exposing your employees to harmful chemicals or storage areas. Look for ways to isolate your workflow from pest access. Be certain that your facility is airtight and sealed with filtration of molds, spores and live organisms in your air intake areas. Air showers at your access points are important to screen your employees on their way into your gowning areas and grow facility. Clothing should be standardized and shoe coverings or crocs should be provided for all employees that access your interior. Look for ways to stop all pests (embedded, crawling, hopping or flying) in all of your room assignments (mothers, clone, veg, flower, trim and drying). This can be improved with shoe baths, sticky mats, frequent hygiene (hand washing and cleaning stations) and procedures for entry.

Always consider requiring hair & beard nets, shoe covers and disposable gloves in plant sensitive areas.

Chemical Access & Protective Equipment

Figure 2: Example Facility Map – Understand Workflow & Barriers to Pest Access

Personal protection equipment (PPE) is very important to protect any employee that will come in contact with materials, liquids or vapors for chemical resources. Establish procedures for chemical use and train employees in the safe handling of these materials. Typical equipment includes high density chemical protective gloves, boots, respirators, Tyvek (or equivalent protective wear) suits and eye protection or goggles.

Chemical access areas and their use should be restricted to employees familiar with their authorized application. Always remember that cannabis is an accumulator plant, and it will absorb and hold onto chemical treatments. Appropriate isolation and safety procedures must be followed for chemical use. Not following these restrictions can expose your employees to dangerous chemicals or get your entire harvests rejected at testing.

Facility Map & Workflow

Because insects would like to be everywhere and they come in many types (root zone, crawling, flying, microscopic, bacterial or biofilm), the facility workflow must understand where they are and how they might migrate if they penetrate your defenses. Note airflows in your rooms and fan locations so migrations can be predicted once an infestation is located. Where are your opportunities for full clean-up and disaster recovery in your building? Where should you stage maintenance filters, test kits, water and cleaning materials. How best to clean up and dispose of sealed garbage containers or cleaning materials?

Operational Cleaning & Post-Harvest Reset

When compiling your preventative measure documents, it is critical to create a repeatable operating procedure for cleaning and sanitizing your rooms, systems, and growing spaces after each harvest. Plant material handling, cleaning surfaces and wipe methods should all be documented in your Standard Operating Procedures (SOPs). Define what “clean” is. Removing plants and plant debris is pretty clear but define how to drain reservoirs, clean pipes, change filters and clean and sterilize your rooms. Operators must be trained in these SOPs and reminded of their content on a regular schedule. This is how you avoid outbreaks that can crush your profits.

Physical Barriers & Maintenance

Document your sealed spaces and define your normal room and access door barrier interfaces. Review the status of any known cracks or gaps in your perimeter. Are there any known leaks or piping that has been seen as a risk or a problem in the past? Are there any discoloring or resident mold locations (Never happens, right?). Baseline how much time and people resource a harvest operation and cleaning effort should take. Will you do this after every harvest or compromise your risk by delaying to every third or fourth harvest? Create your barrier SOP.

Environmental Control & HVAC

Managing the air quality provided to your plants is critical to your yields. Controlling CO2, air movement rates (the leaf happy dance), humidity, air filtration and sterilization methods must be maintained and cleaned on a regular basis. Do you need to change the HEPA or other particulate filters? Is there any UV light sterilization maintenance? We have all seen the home HVAC air conduit cleaning commercials. Your commercial facility is no different. How will you clean your air and water plumbing systems? How often will you perform this full reset? When will you calibrate and data log your sensors for temperature, humidity, CO2 and water resources? Put everything about your environmental set points into your maintenance document and decide when to validate these. Molds, mildews and biofilm hazards are all waiting for unmonitored systems to open the door for access.

In Conclusion, This Week

If you’re an IPM nerd and this dynamic topic did not put you to sleep, you can read more detail and examples for your integrated pest management procedures in ourcomplete white paper for Integrated Pest Management Recommendations, download the document here.

In our next chapter, Direct Control Options, we will review what you can use to protect or recover control of your facility including both chemical and non-chemical tools and methods. In our final two chapters, we will discuss extermination of the determined pests that breach your defenses. And with great expectations, our final chapter will discuss emergency response and time to go to war!

Part Four comes out next week. See you again soon!

Benefits To Growing Cannabis In A Cleanroom Environment

By Steve Gonzales

1 Comment

For commercial cannabis growers, consistent crop yields are vital to maintaining product profitability, as well as durable profitability. Since cannabis thrives under certain conditions, the more control a cultivator has over those conditions, the easier consistent harvests become.

While factors like humidity, light exposure and water may be easy enough to control in any indoor environment, other influential factors can be more difficult to control, such as mold or other contaminants. Growing in a controlled cleanroom environment ensures healthy, high-quality cannabis by mitigating some harder-to-control threats. For these reasons, growing cannabis in a cleanroom environment is rapidly becoming the gold standard in the industry.

A Closer Look at the Cleanroom Environment

A cleanroom facility is a specially designed room or modular addition designed to support a tightly controlled grow environment for crops. The design of the cleanroom relies on several design features to deter issues with pollutants, such as insects, mold, airborne microbes and dust. Even though cleanroom environments are often affiliated with cultivating certain types of crops, these facilities are also valuable in other industries, such as medicine, biology and pharmaceuticals.

Cleanrooms can be conservatively sized or massive. They can be configured to accommodate different processes, and they can be built to suit a specific grower’s preferences. However, several features are key, such as:

Cleanroom-rated HEPA (high-efficiency particulate arrestor) filtration
Contamination control mats
Positive-pressure airflow systems
Double-door air chambers at entry points
Moisture-resistant wall panels

control the room environment — Preventing contamination can save a business from extremely costly recalls.

One fundamental requirement of a cleanroom is to control the introduction of contaminants into the space. Contaminants can be carried in on the people who visit the space. Therefore, cleanroom implementation must come along with strict protocols when it comes to employee entry into the room. For example, air showers, special gowns, masks and other measures may be required.

The Benefits of Cleanroom Environments for Cultivators

On the surface level, cleanrooms make it possible to achieve a well-controlled environment for cannabis cultivation. However, while this is undeniably important in terms of consistent crop yields and profitability, cleanrooms pose a number of broader advantages for cultivators and end customers.

Meet Laboratory Testing Guidelines and Protocols

For now, states create product testing regulations for cannabis. Most states that have legalized medical or adult use cannabis have created protocols for lab-testing products for pesticides and microbes. When batches of cannabis product do not meet state lab-testing standards, the product can be recalled or destroyed. In 2016, Steep Hill published an alarming study that showed they detected pesticides in roughly 70% of the samples they received and up to one third of all samples would have failed to meet regulatory standards. Cleanrooms reduce a grower’s reliance on pesticides.

Negate the Risk of Fungal Contamination

Cannabis is prone to certain types of fungal spores that can cause severe illness in end customers. For example, Aspergillus mold spores are common in cannabis and can lead to cases of chronic pulmonary aspergillosis. In large doses, Aspergillus mold spores may even cause liver failure due to the carcinogenic mycotoxins the spores produce in the body. Cleanrooms negate the risk of fungal contamination through proper ventilation, particulate control and positive pressure.

Create a Safer Work Environment for Employees

Employees who work in cultivation facilities in the cannabis industry face various occupational hazards. Many of these hazards are related to being in contact with fungicides, mold spores and chemical fertilizers. The exposure can result in issues such as allergic reactions, respiratory irritation and other physical threats. Cleanrooms and how they function can deter many of these risks. For example, the lack of need for fungicide use automatically lowers the risks due to lacking exposure. Further, because protective gear is required to maintain the integrity of the cleanroom, there is less of a chance an employee’s skin or respiratory system is exposed to irritants.

Cleanrooms: The Potential Future of Cannabis Cultivation

As cannabis becomes a more robust industry and regulations become more clearly defined, growing standards are bound to change. As speculations of national regulations veer closer to reality, growing cannabis industrially may even mean required cultivation facility upgrades. Cleanroom environments give growers firm control over the health of their crops while ensuring clean products for customers. Therefore, these innovative and health-forward implementations could easily become the norm in the cannabis industry in the future.

Beyond Compliance: Understanding and Combating Contamination

By Jill Ellsworth MS, RDN, Tess Eidem, Ph.D.

No Comments

As an emerging field in cannabis, contaminant testing remains a gray area for many businesses. The vast differences in state-by-state regulations, along with the frequent changes of previously established rules make testing a difficult, time-consuming process. But at its core, the science and reasoning behind why we test cannabis is very clear – consumer safety and quality assurance are key factors in any legal, consumer market. The implications of federal legalization make cannabis testing even more important to the future of the cannabis supply chain. Understanding the types of contaminants, their sources and how to prevent them is essential to avoiding failures, recalls and risking consumer safety.

When talking about cannabis contaminant testing there are four groups of contaminants: pesticides, heavy metals, foreign materials and microbes. The microbes found on cannabis include plant pathogens, post-harvest spoiling microbes, allergens, toxin release and human pathogens. While all of these can be lurking on the surface of cannabis, the specific types that are tested for in each state vary widely. Understanding the full scope of contaminants and looking beyond state-specific compliance requirements, cultivators will be able to prevent these detrimental risks and prepare their business for the future.

Environmental controls are essential to monitor and regulate temperature and humidity

Beyond just the health of the plant, both medical patients and adult use consumers can be adversely affected by microbial contaminants. To immunocompromised patients, Aspergillus can be life-threatening and both adult use and medical consumers are susceptible to allergic reactions to moldy flower. But Aspergillus is just one of the many contaminants that are invisible to the human eye and can live on the plant’s surface. Several states have intensive testing regulations when it comes to the full breadth of possible harmful contaminants. Nevada, for example, has strict microbial testing requirements and, in addition to Aspergillus, the state tests for Salmonella, STEC, Enterobacteriaceae, coliforms and total yeast and mold. Over 15 states test for total yeast and mold and the thresholds vary from allowing less than 100,000 colony forming units to allowing less than 1,000 colony forming units. These microbes are not uncommon appearances on cannabis – in fact, they are ever-present – so understanding them as a whole, beyond regulatory standards is a certain way to future-proof a business. With such vast differences in accepted levels of contamination per state, the best preparation for the future and regulations coming down the pipeline is understanding contamination, addressing it at its source and harvesting disease-free cannabis.

The risk of contamination is present at every stage of the cultivation process and encompasses agricultural practices, manufacturing processes and their intersection. From cultivation to manufacturing, there are factors that can introduce contamination throughout the supply chain. A quality control infrastructure should be employed in a facility and checkpoints within the process to ensure aseptic operations.

Microbial monitoring methods can include frequent/consistent testing

Cultivators should test their raw materials, including growing substrates and nutrient water to ensure it is free of microbial contamination. Air quality plays an important role in the cultivation and post-harvest processes, especially with mold contamination. Environmental controls are essential to monitor and regulate temperature and humidity and ensure unwanted microbes cannot thrive and decrease the value of the product or make it unsafe for worker handling or consumers. Developing SOPs to validate contact surfaces are clean, using proper PPE and optimizing worker flow can all help to prevent cross-contamination and are part of larger quality assurance measures to prevent microbes from spreading across cultivars and harvests.

Methods of microbial examination include air quality surveillance, ATP surface and water monitoring, raw materials testing, and species identification. Keeping control of the environment that product is coming into contact with and employing best practices throughout will minimize the amount of contamination that is present before testing. The solution to avoiding worst case scenarios following an aseptic, quality controlled process is utilizing a safe, post-harvest kill-step, much like the methods used in the food and beverage industries with the oversight of the FDA.

The goal of the grower should be to grow clean and stay clean throughout the shelf life of the product. In order to do this, it is essential to understand the critical control points within the cultivation and post-harvest processes and implement proper kill-steps. However, if a product is heavily bio-burdened, there are methods to recover contaminated product including decontamination, remediation and destroying the product. These measures come with their own strengths and weaknesses and cannot replace the quality assurance programs developed by the manufacturer.

The Path Forward to a Safer Cannabis Industry

By Roshan Sebastian

1 Comment

Two decades ago, California became the first state to legalize the medical use of cannabis. In 2021, medical use of cannabis is legal is 36 US states, and 17 states allow adult (‘recreational’) use. This trend of rapid legalization of the cannabis industry, while encouraging for industry growth, attracts more attention from federal regulatory bodies such as the Occupational Safety and Health Administration (OSHA). Following a number of incidents and near misses, cannabis facilities have been increasingly frequented by OSHA visits, leading to a spike in citations and fines. A review of past OSHA citations reveals that the most common citations in the cannabis industry pertains to the employer’s lack of awareness about the hazardous nature of some operations and materials handled in the facility. This leads to an absence of a formal fire prevention plan, lack of proper hazardous chemical training, deficiency in proper documentation related to workplace injury and limited evaluation of required personal protective equipment (PPE).¹

Cannabis industry data suggests that as of today, an incident is often followed by an OSHA inspection. This naturally leads to the facility asking, ‘How do we prepare for an OSHA inspection and prevent future citations?’ The answer is a combination of identifying and mitigating risks in advance to avoid incidents and developing management systems that support the identification and risk mitigation efforts. Recent collaboration between cannabis business owners and organizations that write codes and standards have provided a framework in which to address the industry’s unique safety challenges to help reduce inherent risk to a facility. These codes and standards typically impact building construction/safety features and operation of the facility, however, additional risk mitigation can be drawn from the best practices already in place in process industries with similar hazards. These process industries have embraced process safety management (PSM) programs, which are built around principles flexible enough to be successfully implemented in the cannabis industry. Adopting such programs will serve the dual purpose of improving the overall safety record of the cannabis industry while enhancing company sustainability² and help avoid events that lead to OSHA citations.

Figure 1. Risk Based Process Safety Management System

The risk-based process safety (RBPS) approach developed by the Center for Chemical Process Safety (CCPS)³ may prove to be the most effective framework to implement PSM programs in the cannabis industry. Unlike the prescriptive regulatory approach provided by OSHA 29 CFR 1910.119, the RBPS methodology recognizes that not all hazards and risks are equal. By assessing risk, an organization can develop an effective management system that will prioritize allocation of limited resources to address the highest risks. Figure 1 shows the four foundational blocks (pillars) of RBPS and the various elements that make up each pillar.

If a cannabis business owner were to develop programs on each of the pillars presented in Figure 1, a comprehensive safety program would be in place that delivers sustainable risk reduction and mitigation. However, as with any industry, the elements can be prioritized and tackled over time, starting with the elements having the most influence on the overall safety of a given facility. For example, a given facility may have great procedures and practices, but may not consistently train or instill employee knowledge or competency. Conversely, a facility may have personnel with great knowledge of hazards and risks, but are less developed with regard to documenting procedures, safe practices or training for new hires. Focusing available resources on the less developed elements will lead to an overall improvement in facility risk, leading to a lower likelihood of an incident and OSHA inspection.

Figure 2. Still image from surveillance video of an explosion at New MexiCann Natural Medicine in July 2015.

As with any industry, positive and negative public perception is driven by the media, which tends to focus on attention-grabbing headlines. The majority of past incidents reported in the news for the cannabis industry were explosions that occurred during the extraction process. One such extraction explosion, shown in Figure 2, occurred in July 2015 at the New MexiCann Natural Medicine facility in Santa Fe, New Mexico. With a focus on the ‘hazard identification and risk analysis’ pillar of RBPS, future such events may be mitigated.

Of the twenty RBPS elements, hazard identification and risk analysis (HIRA) stands out as having the highest potential for immediate impact on the cannabis industry’s safety profile.

HIRA is a collection of activities carried out through the life cycle of a facility to ensure that the risks to employees and the public are constantly monitored to be within an organization’s risk tolerance. The four major areas to analyze are:

Hazards – What are the possible deviations from the design intent?
Consequences – What are the worst possible consequences (or severity) if any deviation occurs?
Safeguards – Are there safeguards in the system to reduce the likelihood of this event?
Risk – Is the risk within the tolerable level? If not, what steps are needed to reduce the risk? (Severity X Likelihood = Risk)

Figure 3. A simplified HIRA flow chart for an Extraction Process

Let us consider an example case where the extraction process utilizes propane or butane as the extracting solvent. Figure 3 shows a simplified HIRA flow chart for the extraction process.

This systematic approach helps to understand the hazards and evaluate the associated risk. In addition, this approach highlights operator training as a crucial safeguard that can be credited to lower the overall risk of the extraction facility. Remember, lack of proper safety training (another element!) is one of the most cited OSHA violations in the cannabis industry. Another advantage to the HIRA methodology is that other safeguards that may be present can be identified, their effectiveness evaluated and additional risk reduction measures may be recognized. This will help business owners allocate their limited resources on the critical safeguards that provide the greatest risk reduction. Identifying, analyzing and solving for potential hazards is a key step in safe operation of a facility and avoiding OSHA citations.

While this article discusses only a single RBPS element, this example demonstrates how best practices from process industries can become a powerful tool for use in the cannabis industry. The “hazard identification and risk analysis” element of the RBPS approach is pertinent not only for the extraction process as discussed above, but also directly applicable to other aspects of the industry (e.g., dust explosions in harvesting and processing facilities, toxic impacts from fertilizers, hazards from the CO₂ enrichment process in growing facilities, etc.).

Cannabis & Chemicals: Why Glove Sourcing is Vital

By Steve Ardagh

No Comments

Freya Farm, a pesticide-free cannabis producer and processor located in Conway, Wash., was recently forced to issue a recall after the chemical o-Phenylphenol, listed under CA Prop 65, was found on its products. Testing traced the antimicrobial compound, known to cause cancer, back to the FDA-compliant food grade gloves used by Freya during packaging.

The reason this could happen with FDA-compliant, food grade gloves needs urgent attention. The production and manufacturing of food contact gloves is largely unsupervised, with limited and infrequent checks on gloves imported into the US. After initial approvals, non-sterile, FDA-compliant food grade gloves are not subject to ongoing controls. This may lead to lower grade and cheap raw materials being used in sub-standard production facilities and processes.

Why “Food Safe” Gloves Aren’t Always Safe

The quality and safety of disposable gloves are limited to Letters of Compliance and Guarantee on the general make and model of the glove, not necessarily the glove you are holding in your hand. There are few controls on the consistency of raw materials, manufacturing processes and factory compliance for both food contact and medical examination grade gloves. Therefore, the opportunity exists for deliberate or accidental contamination within the process of which the Preventive Controls Qualified Individual (PCQI) may not be aware.

Read more about this in Disposable Gloves: The Unregulated Cannabis Threat, previously published in the Cannabis Industry Journal.

The Cost of Recalls

In the words of Freya Farm, “Nothing ruins your day like testing your product, confident it will be clean, only to find it contaminated with some crazy, toxic chemical.” In tracing the issue, the gloves were the last thing Freya Farm tested, as they never suspected something sold as food safe could be the culprit.

A recall of this type can be expensive, as fines range up to $200,000. Since this incident, Freya Farm has implemented a responsible sourcing policy for gloves using supplier Eagle Protect to protect its products, people and brand reputation.

Glove inspection includes five factors of quality controls

Eagle Protect, a global supplier of PPE to the food and medical sectors, is currently implementing a unique proprietary third-party glove analysis to ensure a range of their gloves are regularly checked for harmful contaminants, toxins and pathogens. This Fingerprint Glove Analysis mitigates the risk of intentional or accidental physical, chemical or microbiological glove contamination by inspecting five factors: the use of safe ingredients, cross-contamination potential, cleanliness, structural integrity and dermal compatibility.

Harmful toxins and contaminants in gloves have been identified in many peer reviewed scientific studies. This is now a real issue for companies producing consumer products, especially in industries such as organics and cannabis whose products must be handled by gloves and test clean.

Three key areas that can be tested for in a glove analysis to ensure safe product handling include:

Dermal compatibility tests for toxins and chemicals will flag any toxic chemical, such as o-Phenylphenol
GCMS testing for consistent quality and safety of glove raw materials
Cleanliness tests for pathogens inside and outside the surfaces of gloves – particularly pathogens also required in cannabis testing, such as E. coli and Salmonella, mold and fungus and pesticides.

For cannabis producers responsible glove sourcing is vital, especially as the COVID-related demand for single-use gloves exceeds supply, with poor quality, counterfeit and even reused gloves flooding the market. For producers with a product that rests very much on its quality, it’s important to focus on quality and not just cost when procuring gloves.

The Cannabis Industry Sees Record Growth Despite Continuous Obstacles

By Jay Virdi

No Comments

Worth an estimated $54 to $67 billion, the bourgeoning U.S cannabis industry continues to grow at record pace despite conflicting state and federal laws that cause obstacles at every turn.

This conflict remains a source of uncertainty for retailers, cultivators and the general public. And, unfortunately, the palpable tug of war between the states and the federal government will only increase when legalization is introduced at the federal level, putting tax dollars up for grabs.

A tug-of-war between the states and the federal government makes it difficult for cannabis businesses to obtain bank accounts, insurance and investors. It also means additional security and compliance challenges. It is the reason that the cannabis industry is an unsupportive environment for start-ups and employees who face primitive or even dangerous R&D conditions in order to advance the extraction process.

As cannabis companies fight to grow their market share, many lag behind when instituting a proper risk management structure from R&D to daily operations. Cannabis businesses that haven’t incorporated risk management will need to in 2021, especially when seeking to secure funding from PE firms.

As the 8^th fastest growing industry in the U.S., maturing at more than 25% annually, adult use and medical cannabis sales are unlikely to decrease anytime soon. Rather, experts predict continued growing pains – and gains – to shape the U.S. cannabis industry in 2021.

The COVID-19 pandemic will continue to increase the growth of the cannabis industry— with a few roadblocks

Deemed “essential businesses,” many retail outlets and dispensaries stayed open throughout the pandemic and adopted new ways of serving customers, from curbside pick-up to drive-through windows and deliveries. At the same time, the pandemic hindered growth for some cannabis operations on the cusp of obtaining a license, as many applications were put on hold when state offices closed their doors for months. In some cases that meant raised capital was pulled and funding ceased. For start-ups who are seeking to apply again in 2021, it’ll be an uphill climb.

As a result of routine COVID-19 inspections in 2020, state officials uncovered a host of other issues at cannabis operations, including improper labeling, poor health and safety practices, lack of PPE compliance by staff and customers, incorrect counting of cash and more. In extreme cases, these visits resulted in regulatory fines and shutdowns. This led to the need to use seed money for something other than the organization’s original mission. In 2021, these scenarios are likely to turn into lawsuits from shareholders and activate directors & officers (D&O) and employment practices liability (EPL) claims from laid-off workers. These accusations dovetail with another major charge often levied against cannabis businesses —lightning speed growth without the business operations and risk management protocols necessary to support it.

Many cannabis businesses have not procured the necessary liability insurance coverage for the great risk that come with rapid growth. Whether it’s D&O and EPL policies as in the case above, or cyber, property or general liability (GL) policies, it’s critical to think more holistically about insurance coverage. Cannabis operations need to work with an insurance broker who specializes in the cannabis industry and understands different operations and business location, as exposures vary greatly.

R&D extraction dangers lead to unique risks

In 2021, extraction will be a major focus for cannabis organizations. Operations will continue searching for a competitive advantage to increase yield and develop superior products. Cannabis extractors will experiment with new ways to apply existing laboratory methods utilizing ethanol and CO2 as well as innovative cultivation methods adopted from the agriculture industry, using water and light exposure and different nutrients. R&D becomes a potential liability when cannabis extractors modify the use of existing equipment for a different type of extraction. Flammable products are often required, and explosions can occur.

If you are considering experimenting with R&D, engage your insurance broker to ensure the risk is covered within your existing policies and to explore best practices for experimentation and varying equipment use.

Desire for more security both inside and outside the operation

A cannabis operation’s security risk is two-fold. In light of the looting and civil unrest across the U.S. this year, heightened security measures were necessary for cannabis businesses to secure their goods. Additionally, a common risk— employee theft —increased as well.

Cannabis retail operations maintain a large supply of cash and product. As looting occurred, it was impossible to relocate cannabis product away from retail storefronts as a majority of state regulations prohibit cannabis to be removed from retail facilities. Owners and operators who did so risked being fined for non-compliance or losing their license.

The majority of cannabis theft — as high as 90% by some estimates — is employee related. In many cases, employees in cannabis grow facilities and retail storefronts scheme to cheat employers. Part of the challenge is that state regulations require plant and production facility blueprints to be publicly available. Thieves are using these layouts to plot their infiltration. In other scenarios, cannabis operators are recording walk-throughs of their facilities and publishing online documentaries. These also leave operators vulnerable.

Employers can increase security by restricting access exclusively to employee areas, while also investing in better internal access controls. Conduct an audit of your work areas with your cannabis insurance broker who can provide you with a list of best practices and do’s and don’ts for reducing theft.

Complications continue in compliance, banking and financial services

Even though cannabis is legal for medicinal or recreational use in 43 states, businesses still struggle to secure bank accounts, business loans and insurance coverage. Small local banks and savings and loan businesses may be more willing to engage with cannabis businesses in 2021, while large institutions will keep shying away.

At every stop of the supply chain, cannabis business operators need to be proactive when developing strategies to manage risk. That means implementing risk management protocols to protect their business, their workforce as well as securing the proper insurance coverage.

This also includes growing the cannabis business’ safety net by engaging necessary insurance policies, appropriate to the business’ size and exposure, including cyber, environmental liability and crime policies, or applying for emerging loan programs in an effort to secure additional capital.

Evolution of the industry into 2021 and beyond

While the cannabis industry is evolving and changing, much will ultimately remain the same in 2021. Even if the U.S. government takes steps to federally legalize cannabis, a bill would not go into effect until later in the year at best, more likely in 2022 or beyond. Until a bill is passed, cannabis businesses will look to remain viable beyond the state level. For all cannabis businesses, 2021 will be about building on what they’re already doing and preparing for what will hopefully come next.

Cannabis & COVID: Changes, Advances & Opportunities

By Laura Bianchi

No Comments

The onset of the COVID-19 pandemic sent shockwaves around the world, and they’re still rippling today. Businesses had to quickly pivot from in-person transactions and services to virtual operations, or close down until stay at home orders and other restrictions eased or lifted. While it varies from state to state, due to statutory and rule based operating requirements, requiring facilities to be open a certain amount of hours per week, many were deemed essential. These circumstances create a huge set of complex challenges for anyone in business to navigate, from workers and their families to management and owners, let alone vendors and ancillary businesses.

The bright side is being in an industry where plot twists are not uncommon. Cannabis is legal and highly regulated state by state, illegal on a federal level, so it’s always full of strategic problems to solve. With so many people, businesses, ever-shifting regulations, and financial interests at stake, the need for strategic legal services are the constant. From a purely business and regulatory standpoint, the pandemic has provided some in the cannabis industry with quantum leaps forward in operations and service, and many of them may likely become the new norm.

For people with anxiety (#everydemographic2020) and other debilitating medical conditions, perception is shifting towards the importance and benefits of cannabis as a medicine and alternative therapeutic treatment option, on pace with a larger global trend towards personal and shared wellness. There’s more freedom for consumers to participate recreationally in states with adult use programs too. Extended families and friends in other states may not have the same access to cannabis. We live in a socially driven world, and the awareness of the medicinal properties of cannabis has rapidly grown nationwide across broad demographics. The gateway drug stereotype and stigma is slowly but surely fading away.

Momentum and shift in consumer behavior, need and the shifting perspective of healthcare providers is affecting more state regulators. They’ve worked with the cannabis industry to modify and adjust operational rules as needed to ensure medicinal access during the ever-changing COVID climate. Although current rules and regulations haven’t been lifted in any way, this is a step in the right direction. However, recreational states are less likely to consider that portion of the cannabis market essential and look for ways to prioritize medical dispensaries over recreational.

Medical Cannabis Businesses Deemed Essential

The most immediate problems to solve in many states were social distancing and waiting areas – where to keep patients/customers? There are state guidelines and regulations for operations during COVID, plus CDC general safety and sanitation considerations for workers and consumers alike. Lawyers and regulators are working to make sure that these stores are open and operating safely, have established safety protocols, number of customers allowed inside the store, minimum hours of operation, and to allow for special elderly hours and accommodating patients with compromised immune systems.

One of the biggest operational changes has been an increase in the facilitation of online ordering and curbside pickup to help keep patients safe. Employees are wearing gloves and PPE as an added precaution. This puts the health of the patients and employees first, while still allowing businesses to operate.

More and more patients are not all that enthusiastic about making in-person appointments that may put them at risk. In every state, people waver between venturing out for necessities so they’re buying larger quantities and stocking up when they can, and cannabis is no different. Cash-paying customers must still pay in-person. As federal regulations continue to hinder additional payment options and protections, demand for change grows on both sides.

Staffing in a Pandemic

Like all employers, it’s easier for larger cannabis companies to accommodate employees who are sick or may have been exposed. It’s often more difficult for smaller operations. For many employees, the decision to go into work sick means rent and food, because the employer can’t offer additional sick pay.

In most states, employees have to have some type of state card to work in a store. It’s hard to find replacements and pay for sick leave. There’s no call for a temp agency solution due to clearance needed by cannabis employees. If the business has to shut down, it might not be able to bounce back. So in some states, cannabis businesses have suffered setbacks, but not to the extent as other industries such as hospitality, food and beverage, and tourism.

Crunching the Numbers

The cannabis industry is also excluded from PPP loans and other federal aid. True plant-touching cannabis companies can’t access those funds, adding extra financial stress to operations. The irony is for the majority of cannabis operations nationwide, the biggest change was not the increased regulatory requirements for social distancing, sanitation and safety, it was handling the incredible increase in product demand under circumstances that include financial and staffing stress.

One Arizona-based dispensary was averaging around $300K a month before COVID-19. Today, business has more than tripled to nearly $1 million a month. In mature legal state Colorado, a record $155 million in recreational product sales for June reflects a six percent increase over the previous month’s sales. The Colorado Department of Revenue collected $33.6 million from the industry in June. Colorado’s medical dispensary sales record was set in May, just shy of $43 million, dropping down to about $40.8 million in June. Both are still setting records for business volume. For 2020, revenue already exceeds $203.3 million, in contrast to roughly $302.5 million in cannabis-related revenue in 2019.

Heightened Supply, Demand & Opportunities

Heightened demand and the search for new market ventures means investors are taking notice. People sheltering or working from home are spending more time online, too. Many are searching for healthcare; others for promising investment opportunities. Legalization has been a long journey, state by state. Everyone inside the cannabis and hemp industries has learned to roll with the punches – expect ongoing legal needs, and to do strategic short- and long-term planning. How to anticipate change and pivot on a dime. It’s a must.

With the healthcare system struggling or strained in many areas of the country, non-essential primary care has shifted to telemedicine. Federally, the DEA granted permission to do so that extends for the duration of the COVID-19 public health emergency. The problem? State-level regulations may prohibit the prescription of Schedule III drugs via telemedicine, or limit the amount and refills. For essential healthcare, limited appointments or emergency-only availability remains a concern. Innovative new cannabis products help fill that gap.

There will be more challenges as elections approach and beyond. For those in cannabis, we’re used to being ready for anything. Stay tuned.

3 Ways IP Security Cameras Can Help Cannabusinesses Comply with COVID-19 Health Requirements

By Jeremy White

No Comments

The cannabis industry, like many others, felt the effects of the stay-at-home orders issued in March in response to the COVID-19 healthcare crisis. While medical cannabis companies were considered “essential” in most states, many recreational dispensaries had to close their doors, or pivot to a curbside pickup operations model. According to the State of the Cannabis Industry 2020 report, following a two-week spike in mid-March, as consumers stockpiled product ahead of stay-at-home mandates, sales took a temporary downturn.

The industry rebounded in a big way, however. The report notes that, since April 20, cannabis sales have steadily increased, and are, in fact, up approximately 40% from 2019. But while medical and recreational dispensaries are now open to the public and thriving, it’s far from business as usual.

Like any other retail store, cannabusinesses must follow local- and state-issued health and safety mandates designed to prevent the spread of COVID-19. Complying with these new requirements can be difficult for business owners and management teams on a normal business day – never mind in today’s climate, where demand for cannabis products continues to soar.

Turning to Technology

With more health regulations to follow than ever before and stores experiencing a consistent increase in daily foot traffic, it’s no longer realistic to expect managers to manually monitor every employee and customer to make sure guidelines are met. For example, it’s difficult to manage social distancing within the store – but there are commonly lines outside of cannabusinesses, where social distancing and mask-wearing precautions also need to be followed. Wouldn’t you rather have managers spend their time on customer service and initiatives that will deliver business value, rather than spending time making sure people are following safety protocols?

Technology can help mitigate these new health compliance challenges – and you may even already have the solution deployed: Internet Protocol (IP) security cameras. Often implemented by businesses as a security tool, IP cameras are now also an effective way to ensure employees and customers are following health and safety protocols.

Most IP cameras are equipped with artificial intelligence (AI) that can analyze information in real-time and make split-second response decisions. In the context of health compliance, they can be trained over time to recognize when requirements are not being followed and immediately alert the appropriate managers. This means managers only need to address violations, rather than observing everyone all the time, and they can resolve compliance gaps as they’re happening. In other words, AI takes on the compliance burden for you. And, as an added bonus, many AI-enabled surveillance systems give managers the ability to pull up live video feeds from their smartphone, so they can conduct compliance checks remotely, at any time. This is especially helpful to managers covering multiple stores (suddenly, they can be in more than one place at a time!).

Here are three specific ways IP security cameras can help dispensaries and other cannabusinesses ensure compliance with COVID-19-prompted health guidelines:

Social distance monitoring

Six-feet social distancing rules are now the norm across the U.S., and IP security cameras are able to measure the space around employees and customers to detect when the six-foot rule is violated. For example, some systems place a ring around each person, and the ring’s color changes when people come within six feet of each other. This capability can be helpful when trying to do things such as supervise the line to get into your store, manage your checkout queue, or monitor the distance between customers browsing in store aisles.You can use IP security cameras to create a healthier and safer work environment

Occupancy management

In many states, organizations must follow orders that restrict occupancy to 50% capacity. Rather than having an employee at your front door tallying the number of people going into and out of your store, IP security cameras can do the counting for you. With this capability, you can control foot traffic and keep the number of shoppers within defined occupancy requirements – without having to allocate personnel to do the task manually.

Face mask detection

AI-enabled IP security cameras can also help businesses comply with mandatory face mask orders. The technology can be trained to detect employees and customers who aren’t wearing face masks or other required personal protective equipment, and then alert appropriate management personnel.

A Dual Purpose – Security and Compliance

IP security cameras now have a dual purpose. Beyond simply helping organizations protect their premises from crime, they now also empower them to ensure compliance with health and safety requirements. You can leverage the technology to remediate compliance issues in real-time and demonstrate to public officials that your business remains in compliance with all health mandates. Most importantly, you can use IP security cameras to create a healthier and safer work environment – and, in these uncertain times, this is a certainty you can count on.
