Reducing Cross Contamination in Your Lab

By Nathan Libbey

Cross Contamination

Cross Contamination – noun – “inadvertent transfer of bacteria or other contaminants from one surface, substance, etc., to another especially because of unsanitary handling procedures. – (Mariam Webster, 2021). Cross contamination is not a new concept in the clinical and food lab industries; many facilities have significant design aspects as well as SOPs to deliver the least amount of contaminants into the lab setting. For cannabis labs, however, often the exponential growth leads to a circumstance where the lab simply isn’t large enough for the number of samples processed and number of analytical instruments and personnel needed to process them. Cross contamination for cannabis labs can mean delayed results, heightened occurrences of false positives, and ultimately lost customers – why would you pay for analysis of your clean product in a dirty facility? The following steps can save you the headaches associated with cross contamination:

Wash (and dry) your hands properly

Flash back to early pandemic times when the Tik Tok “Ghen Co Vy” hand washing song was the hotness – we had little to no idea that the disease would be fueled mostly by aerosol transmission, but the premise is the same, good hand hygiene is good to reduce cross contamination. Hands are often the source of bacteria, both resident (here for the long haul; attached to your hands) and transient (easy to remove; just passing through), as they come into contact with surfaces from the bathroom to the pipettor daily (Robinson et al, 2016). Glove use coupled with adequate hand washing are good practices to reduce cross contamination from personnel to a product sample. Additionally, the type of hand drying technique can reduce the microbial load on the bathroom floors and, subsequently tracked into the lab. A 2013 study demonstrated almost double the contamination from air blade technology versus using a paper towel to dry your hands (Margas et al, 2013).

Design Your Lab for Separation

Microbes are migratory. In fact, E. coli can travel at speeds up to 15 body lengths per second. Compared to the fastest Olympians running the 4X100m relay, with an average speed of 35 feet per second or 6 body lengths, this bacterium is a gold medal winner, but we don’t want that in the lab setting (Milo and Phillips, 2021). New lab design keeps this idea of bacterial travel in mind, but for those labs without a new build, steps can be made to prevent contamination:

  • Try to keep traffic flow moving in one direction. Retracing steps can lead to contamination of a previous work station
  • Use separate equipment (e.g. cabinets, pipettes) for each process/step
  • Separate pre- and post-pcr areas
  • Physical separation – use different rooms, add walls, partitions, etc.

Establish, Train and Adhere to SOPs

Design SOPs that include everything- from hygiene to test procedures and sanitation.

High turnover for personnel in labs causes myriad issues. It doesn’t take long for a lab that is buttoned up with cohesive workflows to become a willy-nilly hodgepodge of poor lab practices. A lack of codified Standard Operating Procedures (SOPs) can lead to a lab rife with contaminants and no clear way to troubleshoot the issue. Labs should design strict SOPs that include everything from hand hygiene to test procedures and sanitation. Written SOPs, according to the WHO, should be available at all work stations in their most recent version in order to reduce biased results from testing (WHO, 2009). These SOPs should be relayed to each new employee and training on updated SOPs should be conducted on an ongoing basis. According to Sutton, 2010, laboratory SOPs can be broken down into the following categories:

  • Quality requirements
  • Media
  • Cultures
  • Equipment
  • Training
  • Sample handling
  • Lab operations
  • Testing methodology
  • Data handling/reporting/archiving
  • Investigations

Establish Controls and Monitor Results

It may be difficult for labs to keep tabs on positivity and fail rates, but these are important aspects of a QC regimen. For microbiological analysis, labs should use an internal positive control to validate that 1) the method is working properly and 2) positives are a result of target analytes found in the target matrix, not an internal lab contamination strain. Positive controls can be an organism of choice, such as Salmonella Tranoroa, and can be tagged with a marker, such as Green Fluorescent Protein in order to differentiate the control strain. These controls will allow a lab tech to discriminate between a naturally contaminated specimen vs. a positive as a result of cross-contamination.

Labs should, in addition to having good QC practices, keep track of fail rates and positivity rates. This can be done as total lab results by analysis, but also can be broken down into customers. For instance, a lab fail rate for pesticides averages 4% for dried flower samples. If, during a given period of review, this rate jumps past 6% or falls below 2%, their may be an issue with instrumentation, personnel or the product itself. Once contamination is ruled out, labs can then present evidence of spikes in fail rates to growers who can then remediate in their own facilities. These efforts in concert will inherently drive down fail rates, increase lab capacity and efficiency, and result in cost savings for all parties associated.

Continuous Improvement is the Key

Cannabis testing labs are, compared to their food and clinical counterparts, relatively new. The lack of consistent state and federal regulation coupled with unfathomable growth each year, means many labs have been in the “build the plane as you fly” mode. As the lab environment matures, simple QC, SOP and hygiene changes can make an incremental differences and drive improvements for labs as well as growers and manufacturers they support. Lab management can, and should, take steps to reduce cross contamination, increase efficiency and lower costs; The first step is always the hardest, but continuous improvement cannot begin until it has been taken.

Priorities During the Pandemic: How to Run a Lab Under COVID-19

By Dr. Peter Krause, Udo Lampe
No Comments

During the COVID-19 pandemic, most testing laboratories have been classified as relevant for the system or as carrying out essential activities for national governments. Therefore, it is crucial to maintain activities and optimally assess the changes that are occurring, framed within the spread of the SARS-CoV-2 virus. Analytica Alimentaria GmbH, a testing laboratory with its headquarters in Berlin, Germany and a branch office in Almeria, Spain, decided to focus its management on the analysis of events and the options available, at the legal and employment level, to ensure continuity of activities and reducing, as much as possible, the damage for the parties involved: employees and company. Accredited by the International Accreditation Service (IAS) to ISO/IEC 17025:2017, Analytica Alimentaria GmbH is required to implement risk-based thinking to identify, assess and treat risks and opportunities for the laboratory. Since March 12, 2020 a crisis committee was established, formed by the six members of the company’s management, covering general management, human resources, direction of production, finance and IT. The committee meets every day and it intends to:

  • Minimize the risks of contagion
  • Be able to continue providing the service required by our clients
  • ensure that the company as a whole will survive the economic impact of the crisis
  • Take measures that are within the legality of both countries where the laboratory operates (Spain and Germany),
  • Manage internal and external communication related to the crisis

To achieve correct decision making, daily meetings of the committee were established, to review the situations that were presented day after day and the actions that should be carried out. Each decision was analysed in a prioritized, objective, collaborative and global way.

The basis of the lab’s action plan was a well-developed risk assessment. In addition to the risk of getting a droplet or smear/contact infection with the coronavirus SARS-CoV-2 (risk I) by contact with other people, psychological stress caused by changing working conditions (home office), contact options and information channels were also identified (risk II).

As a result of the risk assessment, the conclusion was that a mix of various measures is the best form of prevention:

  • Keep distance
  • Avoid “super spreader” events
  • Personal hygiene
  • Regular communication between managers and personnel about the current situation and possible scenarios

The risk assessment took both areas into account. The following assessment was developed together with an external specialist and focused on risk I:

Risk I Assessment Protective measures / hygiene plan
Organisation
Working hours and break arrangements High Limit the gathering of people and ensure a minimum distance:

  • Relocated work, break and mealtimes
  • Create fixed groups of shift-working staff
  • Time gap of 20 min. between the shifts
  • Enable home office wherever it is possible
Third party access Moderate Few but “well-known” visitors:

  • Reduce the number of visits and keep internal contacts to a minimum
  • Ensure the contact chain
  • Inform visitors about the internal rules and obtain written consent
Dealing with

suspected cases

 High Isolation and immediate leave of the company:

  • Contactless fever measurement (in case of typical symptoms)
  • Leave the company or stay at home
  • If the infection is confirmed, find contact persons (including customers or visitors) and inform them about a possible risk of infection
Contact with other persons
Traffic route from home to work Moderate Avoid public transportation:

  • Take a car, bicycle or go by foot
  • Enable mobile work and teleworking
At work High Always keep a sufficient distance of 2.0 m from people:

  • If minimum distances cannot be maintained, wear protective masks or install physical barriers (acrylic glass)
  • Organize traffic routes so that minimum distances can be maintained (one-way routes, floor markings indicating a distance of 2 m)
  • Use digital meetings instead of physical ones
Sanitary facilities Moderate Remove virus-loaded droplet as often as possible:

  • Provide skin-friendly liquid soaps and towel dispensers
  • Shorten or intensify cleaning intervals
  • Hang out instructions for washing hands at the sink
  • Include instructions for proper hand-disinfection
Canteens, tea kitchens and break rooms High One person per 10 m² = minimum:

  • Reduce the number of chairs per table
  • Informative signs in every room, indicating the maximum number of permitted persons
Ventilation High Diluting or removing bioaerosols (1 µm virus-droplets):

  • Leave as many doors open as possible
  • Regular and documented shock ventilation every 30 minutes or more frequently, depending on the size of window
  • Operate ventilation and air-conditioning systems, since the transmission risk is classified as low here
Use of work equipment Moderate Use tools and work equipment for personal use:

  • Regular cleaning with changing use (PC, hand tools, coffee machine, …)
  • If possible, use gloves when using equipment for a larger number of users
Protective masks Moderate
  • Use of protective masks as an additional measure, indicating that this does not replace keeping distance
  • Recommend wearing masks in commonly used areas and explain that they do not protect yourself, but help to protect others
  • Give clear instructions (written and oral) on how to use a mask correctly and explain the use and purpose of different mask-types
  • Distribute masks freely

A number of guidelines and concrete measures addressing the risks related to health issues are already in place. Those health issues in risk group II are more closely related to the psychological effects of the crisis, however, are also more complex to mitigate. The key strategy is communication and, in particular, actively listening to all employees of the company.

Analytica’s robust company culture, based on values established in coordination with the whole staff, has been of significant help during the crisis. The some 150 staff members are organized by over 22 team coordinators. During the crisis, active communication has been intensified significantly. The crisis management team set up regular alignment meetings with all the coordinators and with individual persons with particular situations. This way, not only was it possible to explain the development of the crisis and the subsequent measures, the conversations with coordinators were also the most important source of information enabling the appropriate decisions. The coordinators, closely aligned and in sync with management, were then able to communicate with their team members with a high degree of confidence. One outcome of the communication was a measure that proved very effective in fortifying trust within the company: all measures and evaluations, as well as a chronological review, are published in a dynamic internal report and are made available, with full transparency, to all staff members. Besides the many individual and group alignment meetings (usually held by video conference), this has been a key measure to establish confidence and security within the company.

On the other hand, the company made a great effort to balance the effect of the general closure of kindergartens and schools in Spain and Germany. Each case where staff members were required to care for children at home was studied individually and agreements were established, adapting shifts and making use of time accounts, to allow childcare at home without significant loss of income.

The success of the measures is shown by the continuous work of both laboratories during the crisis. Besides the personal tragedy of a possible infection, the identified risk to the company has the consequence of a (partial) quarantine due to an infected person in contact with the staff and the consequent loss of work-power which might lead, in extreme cases, to a closure of the laboratory. According to the governmental regulation in Germany, if an infection occurs (confirmed by the health department), contact persons cat. 1 (more than 15 min. contact face to face) are identified and sent to quarantine. Other contact persons, e.g. contact persons cat. 2 (same room without face to face) must be identified quickly with the collaboration of the infected person and notified and, if necessary, sent in quarantine. In this case, there is a confirmed emergency plan that maintains the laboratory’s ability to work, defining replacements and alternative work-flow strategies.

It has been part of our strategy to validate all our measures with the relevant guidance documents made available by the official competent institutions. The German Federal Office for Public Safety and Civil Protection (Bundesamt für Bevölkerungsschutz und Katastrophenhilfe) has published a guide, “Crisis Management in Companies, 9-point Checklist” especially for critical infrastructure companies in the CoVid-19 crisis.

Having been classified as a core business enterprise (Spain) and “relevant to the system” (Germany), we consider it important to use them as a reference to confirm our level of alignment with your proposal for crisis management.

An important effect, relevant to any leader in times of crisis, is that the confirmation of all points of such a checklist provides certain peace of mind regarding the question: Have we done everything we could?

Essential Cannabis Businesses Must Protect Employees and Customers During COVID-19 With Sanitation and Social Distancing Practices

By David Laks
No Comments

Unlike their retail neighbors who have been forced to move inventory online to survive, many cannabis businesses are considered essential and remain open during the current pandemic. With that, though, comes a tremendous responsibility to maintain optimal protocol for safe operations and customer shopping.

Whether you run a retail or production operation, allow only essential vendors (i.e. delivery, service companies) into the facility and have non-essential staff telecommute, when possible. Some businesses may want to consider splitting shifts for the management team as well.

Each state and local municipality will have their own rules when it comes to protocols for open retail establishments. Where those are more stringent than the following recommendations, adhere to the more stringent rule.

Cannabis Production Facility Best Practices

While not being face-to-face with cannabis customers on a daily basis, production facilities are the first and possibly only ones to handle the raw product the customer will eventually consume. For this reason, it’s important to conduct a refresh training session on sanitation procedures and new COVID-19 protocol for all production employees. Consider the following critical procedures for cannabis production facilities:

  • Review current production sanitation procedures and adjust accordingly, focusing on high touch points and potentially contaminated surfaces. Include office items such as keyboard, phones, and kitchen areas.
  • Review the business’ call-in sick policy and make sure employees know they can – and should – do so if they’re under the weather.
  • Sanitize high touch points every 30 minutes or less.
  • Instruct employees to wash hands with soap and water for 20 seconds after blowing their nose, coughing, sneezing, going to the bathroom, before eating and when touching any communal surface, including door handles and surfaces. Wear personal protective equipment (PPE) at all times while working with raw product, including gloves and masks.

    control the room environment
    PPE can reduce the risks of spreading disease
  • If an employee coughs or sneezes in a production area, instruct them to do so into the elbow of their outer garment, and immediately change following proper donning techniques. Instruct them to avoid touching their face.

Cannabis Retail Facility Best Practices

Retail cannabis establishments must realize first and foremost that those with compromised immune systems may be frequenting their store to purchase medical cannabis. Consider, evaluate and appropriately publicize protocol relative to employee interactions with customers, including:

  • Enable mobile or order-ahead features along with curbside pickup and contact-less delivery, when possible. Where this isn’t an option, limit the number of customers in the store at a time.
  • Consider moving to appointment-only operations, or restricted hours for those over 65.
  • Reduce store visits by recommending patients order their prescription for the maximum allowable 60 days.
  • Designate an employee to champion personal sanitation and social distancing. Create an entry sanitation station and require all customers to use it upon entry. Maintain social distance of 6-ft. minimum between customers. Place markings on the floor to designate this.
  • Limit sales to only sealed products.
  • Sanitize high touch points twice an hour, including ID check booths, display cases, phones, keyboards, etc. and provide adequate PPE for all, including gloves, masks, etc.
  • Install separation barriers, like thick plastic or plexiglass at each cashier station.

The requirements of keeping an essential business open will vary by location and will likely change as the COVID-19 pandemic evolves. Regularly check for changes to the rules of your local jurisdiction and adapt accordingly.

Home Office HACCP During COVID-19

By Nathan Libbey
1 Comment

With much of the world shutting down and many of us forced to take refuge behind our own doors, we have some time to reflect on what actions led to this. There has been, in my opinion, a clear disconnect between our actions and health outcomes. We need to bridge this gap; We now have a moment to build that bridge. We can start by reassessing our endpoint measurement of health and disease and focusing on what leading measures will impact our lagging results. Think of it as HACCP-lite or home office HACCP. Small changes in the way we think and behave can lead to significant change.

Lagging measures – Lagging measures make great headlines and typically measure an outcome. These are easily quantifiable and therefore receive a good deal of the focus.

Leading measures – Leading measures are inputs that happen during the process and in advance of an outcome.  Leading measures are often difficult to quantify.

This week, Nathan started a “Germ Jar” activity with his kids to track washing.

We are currently focused on the lagging measures for a communicable disease, COVID-19. Illness and death numbers stemming from the pandemic continue to rise, as is expected with more available testing. It is easy for us to dwell on these numbers as they climb and dominate the news. A study in Australia last decade indicated that just over 1% of those experiencing flu like symptoms sought treatment and eventually got tested. I’m not going to use the tip of the iceberg cliché, but there it is. Focusing on the rapidly rising rates of COVID may be easy to do, but it won’t help our future selves.

What we should be doing during this time, however, is looking at our own leading behaviors and how changing them can help prevent this situation from reoccurring.

Here are some inputs we can rethink:

  • Hand washing – The average American uses the restroom 6-7 times per day. This week I started a “Germ Jar” activity with my kids (spring break week!) to track washing. If we wash our hands every time we use the restroom and every time we eat, that’s roughly 10X per day. Our leading indicator of household health, then, is 10 hand washes per day. This principle can, and should be applied to workplaces, including schools, airports and hospitals. What if we had mandatory handwashing prior to airport security and boarding? My estimation is that data would indicate a sharp decline in illness and transmission rates.
  • Disinfecting/Sanitizing – Similar to hand washing, cleaning surfaces serves as a vital indicator of future health. Examples, such as this District in Freeport, Il, indicate that increasing frequency of disinfecting can lead to a dramatic decrease in numbers sick. In my new office setting, we have set a goal via the Germ Jar of 3 times per day wiping down high touch surfaces. As we reenter close-proximity society, we need to have a better understanding of what high touch surfaces are, both for those who are tasked to clean them, as well as those that are doing the touching. Reduction of touches coupled with above washing behaviors post-touch can help prevent disease transmission.

    Nathan’s daughter adding to the Germ Jar
  • Monitoring – Lastly, we need to do a better job at monitoring ourselves and our environments. In my new office, we have enacted a temperature check every morning and night. If we practiced symptom reporting (coughing, sneezing, chills) and monitored temperature in other settings, such as offices and schools, could we start to see pockets of infection and trends? Taking it a step farther, while we invest a tremendous amount of time and money into protecting our food supply from foodborne illness, we rarely discuss preventive monitoring for other diseases, such as influenza and now COVID-19. Technologies are rapidly coming available that will allow us to perform quick diagnostics of both individuals and environments. If we were to monitor the air and surfaces of a school nurse’s office, would we find data that could prevent transmission of disease? Can we transfer HACCP-lite to additional (all) settings?

Over the next weeks and months, we are going to be inundated by the spike in COVID illnesses and deaths. During this time, it is on each of us to realize how our past behaviors led to the state we are in. When we return, viruses will not be absent from the world, our hospitals, schools, offices or our bodies. We can, starting now, begin to measure and change our leading behaviors and begin to shape a healthier future.

Key Points To Incorporate Into a Sanitation Training Program

By Ellice Ogle

Food processing and sanitation

To reinforce the ideas in the article, Sanitation Starting Points: More Than Sweeping the Floors and Wiping Down the Table, the main goal of sanitation is to produce safe food and to keep consumers healthy and safe from foodborne illness. With the cannabis industry growing rapidly, cannabis reaches a larger, wider audience. This population includes consumers most vulnerable to foodborne illness such as people with immunocompromised systems, the elderly, the pregnant, or the young. These consumers, and all consumers, need and deserve safe cannabis products every experience.

GMPSanitation is not an innate characteristic; rather, sanitation is a trained skill. To carry out proper sanitation, training on proper sanitation practices needs to be provided. Every cannabis food manufacturing facility should require and value a written sanitation program. However, a written program naturally needs to be carried out by people. Hiring experienced experts may be one solution and developing non-specialists into an effective team is an alternative solution. Note that it takes every member of the team, even those without “sanitation” in their title, to carry out an effective sanitation program.

Sanitation is a part of the Food and Drug Administration’s Code of Federal Regulations on current Good Manufacturing Practices (GMPs) in manufacturing, packing or holding human food (21 CFR 110). Sanitation starts at the beginning of a food manufacturing process; even before we are ready to work, there are microorganisms, or microbes, present on the work surfaces. What are microbes? At a very basic level, the effects of microbes can be categorized into the good, the bad, and the ugly. The beneficial effects are when microbes are used to produce cheese, beer or yogurt. On the other hand, microbes can have undesirable effects that spoil food, altering the quality aspects such as taste or visual appeal. The last category are microbes that have consequences such as illness, organ failure and even death.In a food manufacturing facility, minimizing microbes at the beginning of the process increases the chance of producing safe food.FDAlogo

Proper sanitation training allows cannabis food manufacturing facilities to maintain a clean environment to prevent foodborne illness from affecting human health. Sanitation training can be as basic or as complex as the company and its processes; as such, sanitation training must evolve alongside the company’s growth. Here are five key talking points to cover in a basic sanitation training program for any facility.

  1. Provide the “why” of sanitation. While Simon Sinek’s TEDx talk “Start with why” is geared more towards leadership, the essential message that “Whether individuals or organizations, we follow those who lead not because we have to, but because we want to.” Merely paying someone to complete a task will not always yield the same results as inspiring someone to care about their work. Providing examples of the importance of sanitation in keeping people healthy and safe will impart a deeper motivation for all to practice proper sanitation. An entertaining illustration for the “why” is to share that scientists at the University of Arizona found that cellphones can carry ten times more bacteria than toilet seats!
  2. Define cleaning and sanitizing. Cleaning does not equal sanitizing. Cleaning merely removes visible soil from a surface while sanitizing reduces the number of microorganisms on the clean surface to safe levels. For an effective sanitation system, first clean then sanitize all utensils and food-contact surfaces of equipment before use (FDA Food Code 2017 4-7).
  3. Explain from the ground up. Instead of jumping into the training of cleaning a specific piece of equipment, start training with the foundational aspects of food safety. For example, a basic instruction on microbiology and microorganisms will lay down the foundation for all future training. Understanding that FATTOM (the acronym for food, acidity, temperature, time, oxygen and moisture) are the variables that any microorganism needs to grow supplies people with the tools to understand how to prevent microorganisms from growing. Furthermore, explaining the basics such as the common foodborne illnesses can reinforce the “why” of sanitation.

    Food processing and sanitation
    PPE for all employees at every stage of processing is essential
  4. Inform about the principles of chemistry and chemicals. A basic introduction to chemicals and the pH scale can go a long way in having the knowledge to prevent mixing incompatible chemicals, prevent damaging surfaces, or prevent hurting people. Additionally, proper concentration (i.e. dilution) is key in the effectiveness of the cleaning chemicals.
  5. Ensure the training is relevant and applicable to your company. Direct proper sanitation practices with a strong master sanitation schedule and ensure accountability with daily, weekly, monthly and annual logs. Develop sanitation standard operating procedures (SSOPs), maintain safety data sheets (SDS’s) and dispense proper protective equipment (PPE).

Overall, sanitation is everyone’s job. All employees at all levels will benefit from learning about proper sanitation practices. As such, it is beneficial to incorporate sanitation practices into cannabis food manufacturing processes from the beginning. Protect your brand from product rework or recalls and, most importantly, protect your consumers from foodborne illness, by practicing proper sanitation.

Sanitation Starting Points: More Than Sweeping the Floors and Wiping Down the Table

By Ellice Ogle
No Comments
Food processing and sanitation

Sanitation is not just sweeping the floors and wiping down the table – sanitation has a wide-ranging function in a cannabis food manufacturing facility. For example, sanitation covers the employees (and unwanted pests), food-contact equipment (and non-food-contact equipment), trash disposal (including sewage), and more. Ultimately, sanitation systems maintain a clean environment to prevent foodborne illness from affecting human health. Fortunately, there are resources and tools to ease into establishing a robust sanitation program.

Overall, the main goal of sanitation is to produce safe food, to keep consumers healthy and safe from foodborne illness. With the cannabis industry growing and gaining legalization, cannabis reaches a larger, wider audience. This population includes consumers most vulnerable to foodborne illness such as people with immunocompromised systems, the elderly, the pregnant, or the young. These consumers, and all consumers, need and deserve safe cannabis products every experience.

FDAlogoTo produce safe food, food manufacturing facilities in the United States must at least follow the Food and Drug Administration (FDA)’s Code of Federal Regulations Title 21 Chapter I Subchapter B Part 117, current good manufacturing practice, hazard analysis, and risk-based preventive controls for human food. Although cannabis is currently not federally regulated, these regulations are still relevant for a cannabis food manufacturing facility since the same basic principles still apply. Also, these regulations are a good resource to simplify a comprehensive sanitation program into more manageable components, between sanitary operations and sanitary facilities. With more manageable components, the transition is smoother to then identify the appropriate tools that will achieve a thorough sanitation program.

Sanitary operations

1) General maintenance of the facilities: The buildings and fixtures of the food manufacturing facility cover a lot of ground – hiring a maintenance team will divide the responsibility, ensuring the entire facility can be maintained in a clean and sanitary condition. Furthermore, a team can build out a tool like a preventative maintenance program to restrict issues from ever becoming issues.

Figure 1: Dirty Cloth Towel in Dirty “Sanitizer” Solution

2) Control of the chemicals used for cleaning and sanitizing: Not all chemicals are equal – select the appropriate cleaning and sanitizing chemicals from reputable suppliers. Obtain the right knowledge and training on proper use, storage, and proper protective equipment (PPE). This ensures the safe and effective application of the chemicals in minimizing the risk of foodborne illness.

3) Pest control: Understand the environment within the facility and outside the facility. This will aid in identifying the most common or likely pests, in order to focus the pest control efforts. Keep in mind that internal pest management programs can be just as successful as hiring external pest control services.

4) Procedures for sanitation of both food-contact and non-food-contact surfaces: Developing sanitation standard operating procedures (SSOPs) provides guidance to employees on appropriate cleaning and sanitizing practices, to balance effective and efficient operations. A master sanitation schedule can control the frequency of indicated sanitation procedures.

5) Storage and handling of cleaned portable equipment and utensils: Cross contamination in storage can be minimized with tools such as controlled traffic flow, signage, training, color coding, and more.

Sanitary facilities

6) Water supply, plumbing, and sewage disposal: Routine inspections of plumbing, floor drainage, and sewage systems prevent unintended water flow and damage.

7) Toilet facilities: Clearly defining standards for the toilet facilities and setting accountability to everyone who uses them will ensure that the toilet facilities are not a source of contamination for the food products.

Food processing and sanitation
PPE for all employees at every stage of processing is essential

8) Hand-washing facilities: Good manufacturing practices (GMPs) include proper hand washing and proper hand washing starts with suitable hand-washing facilities. For example, frequent checks on running water, hand soap, and single use towels ensure that all hands are clean and ready to produce safe food.

9) Trash disposal: While trash can be a source of cross contamination, trash can also attract and harbor pests. Scheduling regular trash disposal and controlling traffic flow of waste are two ways to minimize the risk of cross contamination from trash.

Bonus

Even after meeting these requirements, sanitation programs can be more sophisticated. An example is to institute an environmental monitoring program to verify and validate that the sanitation program is effective. Another example is in identifying and measuring key performance indicators (KPIs) within the sanitation program that can improve not just the sanitation processes, but the operations as a whole. Principally, sanitation is cleanliness on the most basic level, but waste management can encompass sanitation and grow into a larger discussion on sustainability. All in all, sanitation programs must reshape and evolve alongside the company growth.

Sanitation is interwoven throughout the food manufacturing process; sanitation is not a single task to be carried out by a sole individual. As such, it is beneficial to incorporate sanitation practices into cannabis food manufacturing processes from the beginning. Protect your brand from product rework or recalls and, most importantly, protect your consumers from foodborne illness, by practicing proper sanitation.
