As the cannabis market matures and the value chain becomes modernized, it’s important to address product safety in a comprehensive way. In other areas of manufacturing, Hazard Analysis & Critical Control Points (HACCP) has been the standard for reducing hazards both for employees and for the products themselves. A Critical Control Point (CCP) is any spot from conception to consumption where a loss of control can potentially result in risk (Unnevehr, 1996). In the food realm, HACCP has been used to drive quality enhancements since the 1980s (Cichy, 1982).
In a nutshell, HACCP seeks to help identify where a problem may enter a product or environment and how that problem may be addressed before it escalates. In cannabis, these hazards include many of the same problems that food products have: specifically molds, yeasts, and pathogenic bacteria (Listeria, E. coli, etc.). While the current industry standard is to test products at the end stage for these contaminants, this late-stage pass/fail regimen leads to huge lots of destroyed product and a risk for consumer distrust (Yamashiro, 2019). HACCP, therefore, should be applied at every stage of the production process.
Pathogen Environmental Monitoring (PEM) is a tool that can be used to identify CCPs in a cannabis cultivation or processing facility. The main goal of a PEM program is to find a contaminant before it reaches a surface that touches the product or the product itself. PEM is conducted using a pre-moistened swab or a sponge to collect a sample from the cannabis environment. The swab can then be sent to a lab for microbial testing. Keys to an effective PEM are:
1. Start with a broad stroke – When the FDA comes to a facility suspected of producing pathogen-laced food products, they conduct what is known as a Swab-a-thon. A Swab-a-thon is a top to bottom collection of samples, usually totaling 100 or more. Similarly, preemptively swabbing should be the first step in any PEM—swab everything to see what exists as a baseline.
2. Map your scene – identify on a map of your facility the following:
Flow of air and people (where do air and people enter and where do they go?
Identifying the above zones will help deepen your understanding of where contaminants may come into contact with cannabis and how they may migrate from a Non-CCS to a CCS.
3. Plan and execute:
Based on the results of mapping, and Swab-a-thon, identify where and when you will be collecting samples on a consistent and repeatable basis. Emphasis should be placed on areas that are deemed a risk based on 1) and 2). Samples should be collected at random in all zones to ensure comprehensive screening.
4. Remediate and modify:
If you get a positive result during PEM, don’t panic—pathogens are ubiquitous.
Remediate any trouble spots with deep cleaning, remediation devices or other protocols.
Re-test areas that were positive for pathogens to ensure remediation is successful.
Revisit and modify the plan at least once a year and each time a new piece of equipment is added or production flow is otherwise changed.
The steps above are a good starting point for a grower or processor to begin a PEM. Remember that this is not a one-size-fits-all approach to safety; each facility has its own unique set of hazards and control points.
Comprehensive guides for PEM can be found at the links below, many of the concepts can be applied to cannabis production.

A product recall is the removal of a defective product from the market because it can cause harm to the consumer or place the manufacturer at risk of legal action.
Although a recall is not something that companies want to be related to, preparing for it is very critical and it is an important part of crisis management.Product recalls can cost companies million dollars in profit loss and civil damages. The company senior management and employees can also face criminal action, if the investigation shows negligent acts. The company will also face loss of reputation and the trust of its customers.
Although a recall is not something that companies want to be related to, preparing for it is very critical and it is an important part of crisis management.
There are several phases when preparing a recall strategy:
Planning Phase
During the planning phase, a recall plan is developed. A recall plan is the procedure that will be followed by an appointed company’s team during an actual recall. A good recall plan will have the following components:
Definitions of the type of products recalls. According to federal regulations, there are three types of recalls. The company should know what type of recall they are performing to understand the risk the consumer is facing.
A Recall Team. The recall team is the key stakeholders that are responsible for different processes within the company. A good recall team will be multidisciplinary. A multidisciplinary team is a group of people that have different responsibilities within the manufacturing site (i.e. Receiving Manager, QA Manager, etc.) and/or outside (i.e. Legal Counsel, Public Relations, etc.)
A description of the recall team member’s responsibilities must be outlined. A recall coordinator and a backup should be assigned to ensure that there is one person organizing all activities during the recall.
A Communication Plan. It is important that only the appointed person that has the responsibility of external communications (i.e. media, regulators, customers, key stakeholders, etc.). In addition, there should be only one person appointed to handle all the communication within the team (internal communications.)
Documents to be used during the recall are:
Communication documents: Letters to customers, regulators and media must be drafted and kept on hand for use during the crisis.
Forms that will be used to keep track of product inventory on hand (still in the site), product being returned and product being destroyed.
A Traceability Procedure should be in place to ensure that materials used in the manufacturing of the finished good can be traced from the time of the delivery to the facility and throughout the product manufacturing process. In addition, traceability must also be provided for finished goods from the manufacturing site to its first point of distribution. This is known as traceability one step back (materials used) and one step forward (first point of distribution.)
A plant tagged with a barcode and date for tracking
A description of (or reference to) product quarantine (product hold) procedures that must be followed to ensure that the product that is still at the site do not leave the facility.
Product Destruction The company must outline (or reference) how product will be destroyed during a recall process.
Implementation Phase
There are three processes that need to be followed when implementing the recall plan:
Training: The recall team must be trained on their roles and responsibilities. Employees working at the site will be receiving directives from the appointed recall team members. It is also important that they are aware about the recall plan and understand the importance of urgency during the situation.
Exercise: It is important that the company doesn’t wait until the incident occurs to ensure that everyone in the team understands their roles and responsibilities during the recall. Therefore, annual testing of the procedure is imperative. This implies creating a “mock recall” situation and providing the information to the team to evaluate if they fully understand their role and responsibilities. This also allows the testing of the traceability protocols and systems that have been put in place by the site. Ensure that the team understands that this is an exercise and not an actual recall. You don’t want the team members going through the emotions that an actual recall gives. However, stress the importance of their participation during this exercise. You do not communicate to customers, media or regulators during a recall exercise.
Execution: This is the actual recall and full implementation of the plan. During the actual recall, you communicate to the regulators, customers and media. The company must also conduct daily recall effectiveness checks by using the forms developed for tracking product inventory, recovery and destruction.
Identify root cause and implement corrective actions. Root cause(s) will be identified during the recall process by analyzing the information resulting from the investigation of the incident. Regulatory agencies will actively participate in the discussion for identifying in the implementation of corrective actions.
Improvement Phase
The recall team should always meet after the recall exercise or the actual recall incident. The team must evaluate what positive or negative outcomes resulted from the process. If there are gaps identified, these need to be closed, so the process is improved.
Success in the cannabis industry is driven by a company’s ability to adapt to an ever-changing market and meet the demands of the evolving consumer. Selecting the right business management solution to handle the complexities of the growing cycle as well as daily operations and compliance requirements necessitates diligent research. Ensuring that the selected technology solution has a centralized database in a secure platform designed to reinforce quality throughout company operations is essential in today’s competitive industry. An ERP solution with integrated CMS capabilities helps businesses strengthen supply chain management by seamlessly incorporating cannabis cultivation with day-to-day company operations to efficiently deliver seed to sale capabilities and meet marketplace demands.
What are ERP & CMS?
Enterprise resource planning (ERP) is a business system in which all data is centralized – including finances, human resources, quality, manufacturing, inventory, sales and reporting. A cultivation management system (CMS) is an extension of an ERP solution to manage cannabis greenhouse operations, including growing, inventory and labor needs. A CMS maintains a detailed level of tracking to account for continuous cannabis growth periods that require extensive monitoring and incur a multitude of expenses. In an integrated solution, both the ERP and CMS data are managed under the same secure database to provide a forward and backward audit trail of all business processes. This visibility encompasses the entire supply chain from the management of supplier relationships to distribution – including growing, cultivating, extracting, manufacturing and shipping.
How do ERP & CMS strengthen supply chain processes?
Tracks individual plants and growth stages – By tracking plant inventories at the individual plant level in real-time with a unique plant identifier, greenhouse operations are optimized – monitoring the entire lifecycle of the plant throughout the germination, seedling, vegetative and flowering stages. Audit trails maintain regulatory compliance, including information such as terpene profiles and THC and CBD potency. Monitoring genealogy, mother and cloning, crossbreeding, plant genetics and clone propagation are key to success in this industry. Strain tracking is equally important, including identifying which strains are performing best, producing the most yield and how they are received by the marketplace. Tracking of the entire supply chain includes the recording of plant health, harvesting techniques, production, growth, costs, lab testing and batch yields – without any gaps in information.
A plant tagged with a barcode and date for tracking
Optimizes growing conditions to increase yields – By automatically documenting and analyzing data, insights into plant and greenhouse activities create streamlined processes for an optimal cannabis cultivation environment. This includes the monitoring of all growing activities such as space, climate, light cycles, moisture content, nutrient applications, fertilizer and other resources, which all have an effect on plant growth and yields. Most importantly, labor costs are monitored, as it is the highest expense incurred by growers. In an industry for which many companies have limited budgets, enabling efficient greenhouse planning, automation and workflows reduces overhead costs.
Integrates with regulatory compliance systems – Compliance is a mandatory part of the cannabis business, and many companies haven’t expended the effort to ensure their processes are meeting regulations. This has placed their licensing and business at risk. An integration that automates the transfer of required reporting information from the ERP to state government approved software such as METRC, Biotrack THC and Leaf Data Systems to ensure regulatory compliance is imperative. This streamlined process assures that reporting is accurate, timely and meets changing requirements in this complex industry.
Facilitates safety and quality control – With an ERP solution tracking all aspects of growing, manufacturing, packaging, distribution and sales, safety and quality are effectively secured throughout the supply chain. Despite the lack of federal legality and regulatory guidelines, proactive cannabis producers can utilize an ERP’s automated processes and best practices to ensure safe and consistent products. By standardizing and documenting food safety procedures, manufacturers mitigate the risk of cannabis-specific concerns (such as aflatoxins, plant pesticide residue, pest contamination and inconsistent levels of THC/CBD potency) as well as dangers common to traditional food manufacturers (such as improper employee procedures and training) for those in the edibles marketplace. Food safety initiatives and quality control measures documented within the ERP strengthen the entire supply chain.
Maintains recipes and formulations – In manufacturing, to achieve product consistency in regards to taste, texture, appearance, potency and expected results, complex recipe and formula management is a necessity – including monitoring of THC and CBD percentages. The calculation of specific nutritional values to provide accurate labeling and product packaging provides necessary information for consumers. Cannabis businesses have to evolve with the consumer buying habits and marketplace saturation by getting creative with their product offerings. With integrated R&D functionality, the expansion of new and innovative edibles, beverages and forms of delivery, as well as new extractions, tinctures, concentrates and other derivatives, helps to meet consumer demands.
Handles inventory efficiently – Established inventory control measures such as tracking stock levels, expiration dates and product loss are effectively managed in an ERP solution across multiple warehouses and locations. Cannabis manufacturers are able to maintain raw material and product levels, reduce waste, facilitate rotation methods and avoid overproduction to control costs. With the use of plant tag IDs and serial and lot numbers with forward and backward traceability, barcode scanning automatically links product information to batch tickets, shipping documents and labels – providing the ability to locate goods quickly in the supply chain if necessary in the event of contamination or recall. The real-time and integrated information available helps mitigate the risk of unsafe products entering the marketplace.
By standardizing and documenting food safety procedures, manufacturers mitigate the risk of cannabis-specific concerns
Utilizes user-based software permissions – Access to data and ability to execute transactions throughout the growing stages, production and distribution are restricted to designated employees with proper authorization – ensuring security and accountability throughout the inventory chain.
Manages supplier approvals – Assurance of safety is enhanced with the maintenance of detailed supplier information lists with test results to meet in-house quality and product standards. Quality control testing ensures that critical control points are monitored and only approved materials and finished products are released – keeping undeclared substances, harmful chemicals and impure ingredients from infiltrating the supply chain. When standards are not met, the system alerts stakeholders and alternate vendors can be sought.
Delivers recall preparedness – As part of an edible company’s food safety plan, recall plans that include the practice of performing mock recalls ensures that cannabis businesses are implementing food safety procedures within their facilities. With seed to sale traceability in an ERP solution, mitigating the risk of inconsistent, unsafe or contaminated products is readily maintained. Integrated data from the CMS solution provides greater insight into contamination issues in the growth stages.
An ERP solution developed for the cannabis industry with supporting CMS functionality embodies the inventory and quality-driven system that growers, processors, manufacturers and distributors seek to strengthen supply chain management. Offering a centralized, secure database, seed to sale traceability, integration to compliance systems, in-application quality and inventory control, formula and recipe management functionality and the ability to conduct mock recalls, these robust business management solutions meet the needs of a demanding industry. With a variety of additional features designed to enhance processes in all aspects of your cannabis operation the solution provides a framework to deliver truly supportive supply chain management capabilities.
Last week, just before MJBizCon, PerkinElmer announced a collaboration with Emerald Scientific, allowing Emerald Scientific customers access to PerkinElmer’s portfolio of cannabis and hemp testing products and services. PerkinElmer is a leading instrument manufacturer and analytical method developer. Emerald Scientific is a distributor for scientific lab testing equipment and instrumentation.
Emerald Scientific now offers their customers PerkinElmer products, like their QSight® 420 Triple Quad system LC/MS, the Titan MPS™ Microwave Sample Preparation System, the Clarus® SQ 8 Gas Chromatograph/Mass Spectrometer (GC/MS) and the Flexar™ High-Performance Liquid Chromatography (HPLC) system. This partnership also allows Emerald Scientific customers to utilize the PerkinElmer analytical methods and standard operating procedures (SOPs) for cannabis and hemp testing. That includes SOPs for things like sample preparation, acquisition methods and consumable use. They’ll also be able to shop for lab products like PerkinElmer’s chromatography columns, vials and sample prep products.
According to Greg Sears, vice president and general manager, Food and Organic Mass Spectrometry at PerkinElmer, the cannabis testing market is exploding and this will help labs get their equipment and necessities all in the same place. “With the cannabis and hemp markets continuing to grow rapidly and regulations strengthening, labs increasingly need streamlined access to best-in-class, user-friendly testing solutions geared toward the unique requirements of the industry,” says Sears. ““This collaboration with Emerald Scientific brings together leading cannabis analysis offerings in one place to help labs start up and expand more efficiently. In addition, we can build on the work we have done with Emerald around testing standardization which is important for the science of the industry.”
Kirsten Blake, Vice President of Emerald Scientific, says they are really excited about the partnership. “As regulations become more challenging, laboratory competition intensifies, and the science of the industry receives increasing focus, it is essential to align with organizations dedicated to improving both the quality and throughput of analytics,” says Blake. “After working with PerkinElmer to inform, educate, and advance the cannabis science industry around best practices, we see them as the industry leader for providing analytical instrumentation, methods and SOP’s. By adding their complementary solutions to our existing portfolio, we can now deliver complete packaged analytical solutions to the cannabis and hemp industries.”
The Agriculture Improvement Act, also known as the Farm Bill, was signed into law in December 2018. A major provision in the law legalizes hemp as an industrial crop. In August of 2016, USDA, DEA, and FDA published a Statement of Principles in the Federal Register (FR 53365) that defined industrial hemp as any part or derivative (including seeds) of the plant Cannabis sativa L. with a dry weight concentration of tetrahydrocannabinols not greater than 0.3% (wt/wt).
Globally, the hemp market was estimated at $3.9 billion in 2017 and the hemp seed segment is predicted to grow “at a CAGR of 17.1%” through 2025. Some of the markets affected by hemp production include nutraceuticals, food, textiles, construction materials, and personal care products. It is also anticipated that cannabidiol (a non-psychoactive cannabinoid extracted from hemp) production will grow to support the burgeoning recreational and medicinal cannabis markets in the U.S., Canada and other countries around the world.
In U.S. states and Canada where recreational or medicinal marijuana programs have been legalized, regulations have been defined to assure the safety and quality of the products sold to consumers. These regulations include analytical chemistry and biological assays to identify and quantify pesticides, mycotoxins, heavy metals, residual manufacturing solvents, terpenes, and microbial contaminates. With regards to hemp, the USDA recently released guidelines for testing of hemp. To date, the only required test from the Federal perspective is total ∆9-tetrahydrocannabinol (THC) content < 0.3% by weight. Total THC is essentially the sum of tetrahydrocannabinolic acid (THCA) and THC (Total THC = 0.877(THCA) + THC) but this may be eventually expanded to include all salts and isomers of cannabinols as noted above. Another complication: what constitutes “dry”? The CFR does not answer this.
Agilent Technologies has invested in the development and implementation of the analytical protocol, the services needed to support these assays, the required consumables, reagents, and supplies, and the training of sales and support personnel to comprehensively ensure compliance of hemp with USDA regulations.
Back in September, Nevada officials announced a state-wide investigation into how products with high levels of yeast and mold were sold in dispensaries and alleged that labs could possibly be manipulating potency numbers on certificates of analysis. Then in late November, regulators suspended the license for Certified Ag Labs, a cannabis testing laboratory based in Sparks, Nevada.
Nevada regulators issued a press release alleging that products tested at Certified Ag Labs “may be labeled incorrectly and could contain a different level of THC than what is listed on product packaging.” Randy Gardner, a managing member at Certified Ag Labs told the Las Vegas Review-Journal that investigators showed up to his lab in October twice to collect samples for follow up tests.
After that, Gardner fired back. In a statement sent out shortly after, Gardner said they were accused of lying about THC test results to the Department of Taxation (the agency that regulates cannabis in Nevada).
“The state’s decision to suspend and potentially revoke our license came without warning,” says Gardner’s statement. “This accusation is as baseless as it is appalling, as we have been completely transparent with the state at all times. We take this matter very seriously, and based on my over 30 years of laboratory experience we believe these allegations unconscionable at best.”
“The state came in for their audit then came back and suspended our license without us having a chance to further clarify or refute their findings,” the statement reads. “We hope the state appreciates that a business and its employees’ livelihoods and reputations are at stake. We are pursuing our options and all legal and equitable redress will be on the table.”
The Department of Taxation, which isn’t releasing any more information currently, says they found “inaccurate and misleading” potency test results, once they tested the samples collected from Certified Ag Labs.
The year 2020 may become a pivotal year for cannabis operators and service providers, including increased access to financial services, and increased exposure to product liability lawsuits. On a positive note, if enacted, the Secure and Fair Enforcement Banking Act of 2019 (SAFE Banking Act) promises to enable cannabis businesses to gain access to financial services previously unavailable to them, including banking and insurance services. The House of Representatives passed the SAFE Banking Act of 2019 on September 25th, 2019. Skopos Labs, an automated predictive intelligence service, predicts there is a 52% chance of the SAFE Banking Act of 2019 becoming law. A recent discovery that vitamin E acetate is likely the culprit in the vaping-related illness epidemic may increase the exposure to costly litigation that cannabis businesses face.
An uptick in litigation like that currently affecting the vaping industry may soon affect cannabis businesses. More litigation affecting the vaping industry is due in large part to the growing number of lung injuries and deaths linked to vaping. As of November 13th, 2019, the CDC reported 2,172 cases of lung injury, and 42 deaths linked to vaping. The cases of lung injury and death have predictably resulted in an increase in litigation facing the vaping industry. Most of the plaintiffs in these cases allege they became addicted to vaping but at least two lawsuits go further. In one, a Connecticut man alleges that he suffered a massive, debilitating stroke as a result of vaping, while in another the parents of a teenage girl allege in a proposed class action suit that their daughter has suffered seizures linked to vaping. On November 14th, 2019, the CDC identified vitamin E acetate as a chemical of concern among people with vaping use associated lung injury. Vitamin E acetate is an additive commonly used as a cutting agent in vape cartridges. About 86% of individuals who have either vaping-related lung injuries, or died due to vaping had used a product containing THC.
The increase in perceived exposure cannabis businesses face has increased their interest in obtaining insurance, but unfortunately insurers are not always interested in insuring them. There are at least two reasons that getting insurance can be difficult for cannabis businesses: (1) insurance industry appetite for cannabis risk is very low due to its status under federal law and (2) express coverage exclusions or limitations of cannabis exposures from standard-form coverage are becoming more common. However, even if cannabis businesses are able to obtain insurance, their insurance may cover them for far less than they believe.
The product liability coverage (which is increasingly crucial for both growers and manufacturers given the mounting litigation facing the vaping industry) may cover far less than it at first appears. The interplay of exclusions and limited coverages in many cannabis-specific policies may leave a cannabis business uninsured.
It is vital now more than ever to ensure you are properly protected against loss.Crucial for cannabis businesses to appreciate is the distinction between “occurrence” and “claims-made” coverage triggers as it relates to both the premises on which cannabis businesses operate their business, and the products they sell.
Many cannabis businesses have an occurrence-based general liability insurance that might actually exclude: (1) product-liability risks; (2) any tobacco-related risks; and (3) any risk associated with governmental investigation or enforcement. These exclusions oftentimes concern cannabis businesses because there is a high likelihood one of these risks could manifest itself as an uninsured loss. Still, the costs of eliminating these exclusions in an occurrence-based general liability insurance policy is often large, assuming an insurer is willing to eliminate the exclusions on an occurrence basis at all. Therefore, cannabis businesses often pair their general liability insurance policy with a “claims-made” coverage trigger for products liability. Navigating the waters of managing the differences between “occurrence” and “claims-made” forms are best left to a qualified and experienced insurance professional.
Consult a local insurance professional that understands how to help your business become properly protected in what would be considered a tumultuous market for this burgeoning industry.
It is vital now more than ever to ensure you are properly protected against loss. As a first step, you must determine what your current insurance policy does and does not cover. After a loss, it is too late to change policies. Rely upon someone that knows the market of insuring this industry and has deep experience in managing both occurrence and claims-made policies.

Now that cannabis edibles have been legalized nationally in Canada, many existing and aspiring license holders have been surprised to discover that they must comply with food safety regulations. This became crystal clear when Health Canada published their Good Production Practices Guide For Cannabis in August 2019.
With this development, it should be obvious to everyone that Good Manufacturing Practices (GMP) certifications are simply not enough.
HACCP is a methodology that is all about identifying biological, chemical and physical hazards and determining how they will be controlled to mitigate the risk of injury to humans. Recently, bio-terrorism and food fraud hazards have been added to the list and it is a good idea to address quality hazards as well.
The process of developing a HACCP program involves identifying these hazards with respect to ingredients, materials, packaging, processes and cross-contamination points (explicitly required in Canada only). However, it is a specific ingredient hazard that I’d like to talk about here.
As this market has emerged, I’ve met with many cannabis companies as the onerous levels of knowledge and effort required to build and maintain an effective HACCP program manually has dawned upon the industry. Many are looking for technological solutions to quickly solve this problem. During these discussions, a curious fact has emerged that set off the food safety alarm klaxons around here.
Most people alive today are too young to remember this but, with few exceptions, the standardization of ingredients is a relatively modern phenomenon. It used to be that the fat content of your milk varied from season to season and cow to cow. Over time, the food industry standardized so that, amazingly, you can now choose between milks with either 1% or 2% fat, a level of precision that would border on miraculous to someone born in the early 20th century.
The standardization of ingredients is important in terms of both quality and safety. Take alcohol for example. We know that a shot of spirits generally contains 40% alcohol. Different products may vary from this standard but, if I pour a shot of my favourite Bowmore No.1 single malt in Canada or Tasmania, this year or 10 years from now, I can expect a consistent effect from the 40% alcohol content of the quantity I’ve imbibed.
Imagine a world in which this was not the case, where one shot would be 40% but the next might be 80%. Things could get out of control quite easily at the 80% level so, to avoid this, distillers monitor and blend their product to ensure they achieve the 40% target, which is called the “standardization marker”.
With respect to cannabis, the obvious standardization marker is THC. During the manufacturing process, edibles manufacturers do not normally add cannabis flower directly into their products but instead add a THC concentrate produced during previous production steps. However, we’ve found that the wisdom of standardizing these concentrates has not yet dawned upon many in the industry, which is alarming at best and dangerous at worst.
The reason for this is that, since cannabis is inherently a heterogeneous plant, one cannot precisely achieve a particular marker value so the outcome of the concentration process is variable. The food industry long ago overcame this problem by blending or diluting to achieve a consistent marker concentration, but the cannabis industry has not yet adopted this advance.
The cannabis edibles industry is still immature and it will take time to bring all the necessary risk mitigation processes into place but one excellent place to start is to seriously consider standardizing concentrates to a THC marker.Instead, manufacturers simply keep track of the strength of each batch of concentrate and then adjust the quantity added to their recipes to achieve the desired THC content. This seems logical on the surface but presents a serious risk from the HACCP perspective, namely a chemical hazard, “Excessive psychoactive compound concentrations due to human error at levels that may be injurious to human health”.
The reality is that workers make mistakes, which is why it is imperative to mitigate the risk of human error insomuch as possible. One of the best ways to do this is to standardize to avoid the scenario where a worker, faced with a row of identical containers that are differentiated only by a tiny bit of text, accidentally grabs the wrong bottle. The error isn’t caught until the product has been shipped, consumed, and reports of hospital visits start coming in after the authorities trace the problem back to you. You must bear the costs of the recall, your reputation has been decimated and your company is floundering on the financial rocks.
US-based Drip More, LP recently found this out the hard way after consumers complained that their product tasted bad, bitter and/or harsh. An investigation determined that excessive nicotine content was the source of the problem and a voluntary recall was initiated. Affected product that had already been sold in 26 states. The costs of this recall have not been tallied but they will be staggering.
The cannabis edibles industry is still immature and it will take time to bring all the necessary risk mitigation processes into place but one excellent place to start is to seriously consider standardizing concentrates to a THC marker. This strategy is cheap, easy and you’ll never be sorry.
You’ve survived seasons of cannabis cultivations, bringing in quality plants in spite of mold, mites, drought and other challenges that had to be conquered. Extraction methods are sometimes challenging, but you are proud to have a cannabinoid extract that can be added into your own products for sale. Edibles are just waiting to be infused with the cannabinoids, for consumers demanding brownies, gummies, tinctures and almost any food and beverage imaginable. You’ve been through the fire, and now the rest is easy peasy, right?
Avoiding cross contamination should be a priority for edibles manufacturing
Actually, producing edibles may not be so seamless as you think. Just as in the rest of the food industry, food safety practices have to be considered when you’re producing edibles for public consumption, regardless of the THC, CBD, terpene or cannabinoid profile. Once you’ve acquired the extract (a “food grade ingredient”) containing the active compounds, there are three types of hazards that could still contribute to foodborne illness from your final product if you’re not careful- Biological, Chemical and Physical.
Biological hazards include pathogenic bacteria, viruses, mold, mildew (and the toxins that they can produce) that can come in ingredients naturally or contaminate foods from an outside source. Chemical hazards are often present in the kitchen environment, including detergents, floor cleaners, disinfectants and caustic chemicals, which can be harmful if ingested- they are not destroyed through cooking. Physical objects abound in food production facilities, including plastic bits, metal fragments from equipment, staples or twist ties from ingredient packages, and personal objects (e.g., buttons, jewelry, hair, nails.)
There are three main safety precautions that can help control these hazards during all the stages of food production, from receiving ingredients to packaging your final products:
1. Avoid Cross Contamination
Prevent biological, chemical or physical hazards from coming into contact with foods
Keep equipment, utensils and work surfaces clean and sanitized.
Prevent raw foods (as they usually carry bacteria) from coming into contact with “Ready-to-eat” foods (foods that will not be cooked further before consuming).
Keep chemicals away from food areas.
2. Personal Hygiene
Don’t work around foods if you’re sick with fever, vomiting or diarrhea. These could be signs of contagious illness and can contaminate foods or other staff, and contribute to an outbreak.
Do not handle ready-to-eat foods with bare hands, but use a barrier such as utensils, tissues or gloves when handling final products such as pastries or candies.
Wash hands and change gloves when soiled or contaminated.
Wear hair restraints and clean uniforms, and remove jewelry from hands and arms.
3. Time & Temperature control
Prevent bacterial growth in perishable foods such as eggs, dairy, meats, chicken (TCS “Time and Temperature Control for Safety” foods according to the FDA Model Food Code) by keeping cold foods cold and hot foods hot.
Refrigerate TCS foods at 41˚ F or below, and cook TCS foods to proper internal temperatures to kill bacteria to safe levels, per state regulations for retail food establishments.
If TCS foods have been exposed to room temperature for longer than four hours (Temperature Danger Zone 41˚ F – 135˚ F,) these foods should be discarded, as bacteria could have grown to dangerous levels during this time.
As cannabis companies strive for acceptance and legalization on a federal level, adopting these food safety practices and staff training is a major step in the right direction, on par with standards maintained by the rest of the retail food industry. The only difference is your one specially extracted cannabinoid ingredient that separates you from the rest of the crowd… with safe and healthy edibles for all.

In a nutshell, HACCP seeks to help identify where a problem may enter a product or environment and how that problem may be addressed before it escalates. In cannabis, these hazards include many of the same problems that food products have: specifically molds, yeasts, and pathogenic bacteria (Listeria, E. coli, etc.). While the current industry standard is to test products at the end stage for these contaminants, this late-stage pass/fail regimen leads to huge lots of destroyed product and a risk for consumer distrust (Yamashiro, 2019). HACCP, therefore, should be applied at every stage of the production process.
Identifying the above zones will help deepen your understanding of where contaminants may come into contact with cannabis and how they may migrate from a Non-CCS to a CCS.
