HACCP

Hazard Analysis and Critical Control Points (HACCP) for the Cannabis Industry: Part 2

By Kathy Knutson, Ph.D.

HACCP

HACCP is a food safety program developed in the 1960s for the food manufacturing industry, mandated for meat, seafood and juice and adopted by foodservice for the safe serving of meals at restaurants. With state requirements for the safe production of cannabis-infused products, namely edibles, facilities may be inspected against HACCP principles. The cannabis industry and state inspectors recognize the need for safe edible manufacture. Lessons can be learned from the food industry, which has advanced beyond HACCP plans to food safety plans, starting with procurement and including the shipment of finished product to customers.

In my work with the food industry, I write HACCP and food safety plans and deliver training on food safety. In Part 1 of this series, I wrote about the identification of hazards, which is the first step in HACCP plan development. Before we continue with the next HACCP step, I will discuss Good Manufacturing Practices (GMPs). GMPs are the foundation on which HACCP is built. In other words, without GMPs in place, the facility will not have a successful HACCP program. GMPs are required in the food, dietary supplement and pharmaceutical industries, all under the enforcement of the federal Food and Drug Administration (FDA). Without federal regulation for cannabis edible manufacture, there may not be state-mandated requirements for GMPs. Let me warn you that any food safety program will not succeed without proper control of GMPs.HACCP

GMPs cover all of your programs and procedures to support food safety without having a direct, instant control. For example, when brownies are baked as edibles, food safety is controlled by the time and temperature of baking. A written recipe and baking procedure are followed for the edible. The time and temperature can be recorded to provide documentation of proper baking. In the food industry, this is called a process preventative control, which is critical to food safety and is part of a HACCP plan. Failure of proper time and temperature of baking not only leads to an unacceptable product in terms of quality, but results in an unsafe product that should not be sold.

Back to GMPs. Now think of everything that was done up to the steps of mixing and baking. Let’s start with personnel. Facilities for edibles have hiring practices. Once an employee is hired, the employee is trained, and training will include food safety procedures. When working at the job after training, the employee measuring ingredients will demonstrate proper grooming and hand washing. Clean aprons, hairnets, beard nets and gloves will be provided by the facility and worn by the employee. The same goes for the employee that bakes and the employee that packages the edible. One category of GMPs is Personnel.

Edibles facilities are not foodservice; they are manufacturing. A second GMP category is cleaning and sanitizing. Food safety is controlled through proper cleaning and sanitizing of food contact surfaces (FCS). The edible facility will have in place the frequency and methods for cleaning all parts of the facility- outside, offices, restrooms, break room and others. GMPs cover the general cleaning procedures and procedures for cleaning receiving, storage; what we would consider processing to include weighing, process steps and packaging; finished product storage and shipping. Management of the facility decides the methods and frequency of cleaning and sanitizing with greater care given to processing. Without proper cleaning and sanitizing, a facility cannot achieve food safety.

I could go on and on about GMPs. Other GMPs include water safety, integrity of the buildings, pest control program, procurement, sewage disposal and waste disposal. Let’s transition back to HACCP. In Part 1 of this series, I explained identification of hazards. Hazards are one of three types: biological, chemical and physical.

At this point, I am not surprised if you are overwhelmed. After reading Part 1 of this series, did you form a food safety team? At each edibles facility, there should be at least one employee who is trained externally in food safety to the standard that foodservice meets. Classes are offered locally and frequently. When the facility is ready, the next step of training is a HACCP workshop for the food industry, not foodservice. Edibles facilities are not foodservice; they are manufacturing. Many colleges and associations provide HACCP training. Finally, at the least, one employee should attend a workshop for Preventive Controls Qualified Individual.

To institute proper GMPs, go to ConnectFood.com for a GMP checklist. Did you draw up a flow diagram after reading Part 1? With a flow diagram that starts at Receiving and ends at Shipping, the software at ConnectFood.com takes you through the writing steps of a HACCP or food safety plan. There are many resources out there for GMPs, so it can get overwhelming. ConnectFood.com is my favorite resource.

The next step in HACCP development after identification of hazards is to identify the exact step where the hazard will be controlled. Strictly speaking, HACCP only covers process preventive controls, which typically start with a weigh step and end with a packaging step. A facility may also have a step where temperature must be controlled for food safety, e.g. cooling. In HACCP, there are commonly two process preventive controls:

  • Biological hazard of Salmonella and Escherichia coli: the heat step
  • Physical hazard of metal: metal detector

Strictly speaking, HACCP does not include cleaning, sanitizing and supplier approval for procurement of ingredients and packaging. I hope you see that HACCP is not enough. There have been hundreds of recalls and outbreaks due to problems in non-processing steps. The FDA requires food manufactures to go beyond HACCP and follow a written food safety plan, which includes hazards controlled at these steps:

  • Biological hazard of Listeria monocytogenes: cleaning and sanitizing of the processing environment and equipment
  • Physical hazards coming in with ingredients: supplier approval
  • Physical hazard of glass and hard plastic: Here I am thinking of glass breaking or plastic pieces flying off buckets. This is an internal hazard and is controlled by following written procedures. The written document is a Standard Operating Procedure (SOP).
  • Chemical hazard of pesticides: supplier approval
  • Chemical hazard of mycotoxins: supplier approval
  • Chemical hazard of allergens: supplier approval, label check at Receiving and product labeling step

Does a cannabis edible facility honestly not care or not control for pesticides in ingredients because this is not part of HACCP? No. There are two ways for procurement of ingredients in which pesticides are controlled. Either the cannabis cultivation is controlled as part of the samebusiness or the facility works with a supplier to confirm the ingredient meets pesticide tolerances. Strictly speaking, this control is not part of HACCP. For this and many other reasons, HACCP is a good place to start the control of food safety when built on a solid foundation of GMPs. In the same way the food industry is required to go beyond HACCP with a food safety plan, the cannabis industry must go beyond HACCP.

My thoughts will be shared in a webinar on May 2nd hosted by CIJ and NEHA. I encourage you to listen in to continue this discussion.Please comment on this blog post below. I love feedback!

Is There a Looming Supply Bottleneck in California?

By Aaron G. Biros
No Comments

California’s regulated adult use cannabis market has been up and running for around four months now and rumors of a potential supply bottleneck on the horizon are beginning to circulate. There are a number of factors that could have an impact on the cannabis supply in the market, most of which stem from changes in the distribution channels now that the state is implementing new regulations.

Those include a slow rollout in licensing cannabis businesses, new testing requirements, the supply carryover period prior to January 1stas well as new labeling and packaging regulations. In this piece, we are going to examine some of those rumors, see if there might be some truth to them and provide some guidance for what businesses can do to prepare for this.

A Slow Start to Licensing

This one is perhaps the most obvious factor to impact the supply chain in California. Much of the delays in licensing cannabis businesses came from the issue of local control, where businesses needed to get approval from their municipality before getting a state license. In the first month of the new market, it took Los Angeles weeks longer than other counties to begin licensing dispensaries. Whereas San Diego retailers saw a massive influx of customers right away, forcing them to buy up product to meet the high demand. Smaller producers also had trouble getting licenses as quickly as some of the larger ones.

Basically it all boils down to a slow start for the new market, according to Diane Czarkowski, co-founder of Canna Advisors. “The state is requiring businesses to get their local licenses before they can get their state license and that will create a delay in operators being able to bring products to market,” says Czarkowski. She says this is pretty typical of new markets, or when a market experiences dramatic changes quickly. “It could be a brand-new market, like in Hawaii, where the operators were ready with product, but there were no labs to test the products, which caused delays.” In addition to the licensing roll out being slow to start, the temporary licenses initially awarded to businesses are set to expire soon, by the end of April.

Stricter Rules to Come

The same logic goes for the testing regulations. New testing and labeling requirements, according to the Bureau of Cannabis Control regulating the market, will be phased in throughout 2018.

California’s plan for phasing in testing requirements.

The state has already phased in cannabinoids, moisture content, residual solvent, pesticide, microbial impurities and homogeneity testing to some extent. On July 1st, the state will add additional residual solvent and pesticide testing as well as foreign material testing. At the end of 2018, they plan on requiring terpenoids, mycotoxins, heavy metals and water activity testing. All of those tests cost money and all of those tests could impact suppliers’ ability to bring product to market. “Oftentimes regulations require different types of testing to be done to products without recognizing that adequately completing those tests requires different methods, equipment, and standards,” says Czarkowski. “Most labs do not have all of the necessary components, and they are very costly. Producers could wait weeks to get test results back before they know if they can sell their products.”

Back when we spoke with Josh Drayton, deputy director of the California Cannabis Industry Association, about the upcoming changes to the California market, he voiced his concerns with the coming testing rules. “A lot of testing labs are concerned they are unable to test at the state’s threshold for some of these contaminants and pesticides; the detection limits seem very low,” says Drayton. “The testing portion will take years to work out, I am sure we will remove and add different pesticides and contaminants to the list.” California’s testing industry is, however, capable of adapting to changing rules, as they’ve done in the past on more than one occasion. It should be noted that many labs in the state are on the cutting edge of testing cannabis, working with The Bureau to implement the new rules.

Roy Bingham, CEO of BDS Analytics

Cannabis products made prior to December 31st, 2017, did not need to comply with the stricter testing rules that are coming in the next few months. This carryover period allowed dispensaries to have products on the shelves when the new market launched in the beginning of 2018. Retailers knew this rule meant they needed to stockpile product in the event of a supply bottleneck, and it appears much of that product is now sold and running out, according to Roy Bingham, founder and chief executive officer of BDS Analytics. “The true impact of licenses is starting to be felt since the carryover from December buying prior to the licensed market has been sold,” says Bingham. “Some of the major brands have consciously not applied for licenses. Some of that has to do with the flexibility the government has given them to wait.”

A fourth reason for a potential bottleneck could also come from packaging and labeling rules. “There will have to be many modifications to products to ensure they follow the new potency regulations, and many formulations will have to be modified in order to meet new regulations,” says Czarkowski. Distributor licenses, according to The Bureau, have a number of compliance documentation requirements, such as arranging for all product testing, quality assurance and packaging and label accuracy. Everything has to be packaged before it gets to a dispensary, which is a new rule California businesses need to comply with.

Pricing is the Indicator

There are a handful of reasons why prices could increase; some of them are more defined than others, the biggest factor being the tax burden passed on to consumers, where reports showed up to a 40% increase from last year. A price increase in the future could also come from The Bureau implementing testing regulations throughout 2018, as mentioned previously.

If prices were to surge enormously and very quickly, that might be an indicator that a shortage is fast approaching. A dramatic increase in price over this year could squeeze margins for smaller producers, forcing retailers to pass that burden on to consumers as well.“So yes, the rumors are true.”

According to Roy Bingham, there has been a significant increase in pricing in all categories at the retail level. “In January and February, we are seeing about 10% increases per month in average retail prices,” says Bingham. “If we look at concentrates in California during 2017, they averaged about $34 by the end of the year, whereas it was about $31 at the start of 2017. So in January, prices have increased up to $38, which is a bit above trend, but in fact we were seeing a trend upwards before January 1st as well.” Comparing that with edibles pricing, Bingham says we see a clear jump at the start of 2018. “It was basically flat in 2017, averaging $14 roughly almost straight-line across, dipped in December, then in January it jumped to $17 and then to $18 in February, a big increase and significantly more than concentrates,” says Bingham. He also says flower was hovering around $9 per gram in December 2017, but surged above $10 in February 2018.

According to Cannabis Benchmarks, the California wholesale averages surged in the summer of 2017 up to $1,631 by September, then reached their lowest point in December, with their spot index at $1,368. The Cannabis Benchmarks report underlines some important reasons for the changes in pricing, but they also attribute it to the new licensing system.

“Increasing operating expenses for businesses preparing to enter California’s licensed system in 2018 were key to propping up supply side rates in the first six months of 2017. New compliance requirements were being instituted to varying degrees by local governments, while market participants warily eyed draft regulations from state officials for guidance as to how to prepare their sites and facilities to meet under-construction regulatory mandates.”

Their report highlights some very important aspects of the supply chain. “Again, it is likely that the increased costs faced by operators up and down the supply chain exert some upward pressure on wholesale rates, preventing them from steep year-over-year declines that were observed in some of the other major Western markets,” reads the Cannabis Benchmarks report.

So How Can Businesses Prepare?

Well to start, producers should make sure their operations and product are clean and safe. Making sure your product will pass a pesticide test should be top of mind. Dispensaries should also be wise in selecting their suppliers, performing supplier quality audits or some form of verification that they meet your standards is key in a consistent supply chain.

Dr. Jon Vaught, chief executive officer of Front Range Biosciences, believes tissue culture could be a viable solution for some California producers. Using tissue culture, as a form of propagation instead of mothers and clones can be cleaner, cheaper and more efficient, thus allowing growers to keep up with demand and prevent a shortage.

Dr. Vaught says growers could look to tissue culture as a means to “mitigate risk to their supply chain and mitigate the risk of potential loss and improve their ability to efficiently grow their plant.” Maintaining a disease-free, sterile environment is a huge advantage in the cannabis market. “The real use of tissue culture is to provide disease free, clean, certified material, that has gone through a QA program,” says Dr. Vaught. “In greenhouses, the ability to control your environment is also critical because your margin of error is high. Variations in sunlight, weather, humidity all of these things have an impact in your plants. Technology can help monitor this.”

We’ve covered the basics of tissue culture previously on CIJ, with Dr. Hope Jones chief science officer of C4 Laboratories. She echoes many of Dr. Vaught’s points, firmly believing that, having existed for decades, tissue culture is an effective propagation tool for advanced breeders or growers looking to scale up.It is a complex supply chain that requires systems thinking.

It is important to note they don’t think growers should try this at home. Work with professionals, get the necessary funding, the training and facilities required if this is a project that interest you. “There’s a pretty big barrier to entry there,” Dr. Vaught urges. “The ability to manage thousands or millions of plants in a greenhouse increases risk, whereas in the lab, you’ve got a safe, secure, sterile environment, reducing risk of disease, making things easier to manage. The producers most successful at large scale are controlling those variables to the T.”

Ultimately, one segment of the market can’t prevent a bottleneck. It is a complex supply chain that requires systems thinking. Regulators need to work with producers, manufacturers, retailers, distributors, patients, consumers and laboratories to keep an eye on the overall supply chain flow.

Diane Czarkowski says the California market should prepare for this now if they haven’t already. “We have seen supply issues in every market going through a change. Other potential bottlenecks will occur because former distribution channels will be required to change,” says Czarkowski. “So yes, the rumors are true.”

Washington Lab Conducts Transparency Study

Earlier this week Capitol Analysis Group, a cannabis-testing laboratory based in Lacey, Washington, announced they are conducting a “data-driven Lab Transparency Project, an effort to improve accuracy of cannabis testing results in the state through transparency and a new third-party auditing process,” according to a press release. They plan to look through the state’s traceability data to find patterns of deviations and possible foul play.

The project launch comes after Straightline Analytics, a Washington cannabis industry data company, released a report indicating they found rampant laboratory shopping to be present in the state. Lab shopping is a less-than-ethical business practice where cannabis producers look for the lab that will give them the most favorable results, particularly with respect to higher potency figures and lower contamination fail rates.“Lab shopping shouldn’t exist, because it is a symptom of lab variability,”

According to the press release, their report “shows that businesses that pay for the highest number of lab tests achieve, on average, reported potency levels 2.71% higher than do those that pay for the lowest number of lab tests.” They also found labs that provide higher potency figures tend to have the largest market share.

The goal of The Lab Transparency Project is to provide summaries of lab data across the state, shining a light in particular on which labs provide the highest potency results. “Lab shopping shouldn’t exist, because it is a symptom of lab variability,” says Jeff Doughty, president of Capitol Analysis. “We already have standards that should prevent variations in lab results and proficiency testing that shows that the labs are capable of doing the testing.” The other piece to this project is independent third party auditing, where they hope other labs will collaborate in the name of transparency and honesty. “Problems arise when the auditors aren’t looking,” says Doughty. “Therefore, we’re creating the Lab Transparency Project to contribute to honesty and transparency in the testing industry.”

Dr. Jim McRae, founder of Straightline Analytics, and the author of that inflammatory report, has been a vocal critic of the Washington cannabis testing industry for years now. “I applaud Capitol Analysis for committing to this effort,” says McRae. “With the state’s new traceability system up and running following a 4-month breakdown, the time for openness and transparency is now.” Dr. McRae will be contributing to the summaries of lab data as part of the project.

According to Doughty, the project is designed to be a largely collaborative effort with other labs, dedicated to improving lab standards and transparency in the industry.

The Necessity of Food Safety Programs in Cannabis Food Processing

By Gabe Miller
No Comments

When processing cannabis, in any form, it is critical to remember that it is a product intended for human consumption. As such, strict attention must also be paid to food safety as well. With more and more states legalizing either medical or recreational cannabis, the potential for improper processing of the cannabis triggering an illness or death to the consumer is increasing.

The FDA Food Safety Modernization Act (FSMA) is the new food safety law that has resulted in seven new regulations, many which directly or indirectly impact the production and processing of cannabis. Under FSMA regulations, food processors must identify either known or reasonably foreseeable biological, chemical or physical hazards, assess the risks of each hazard, and implement controls to minimize or prevent them. The FSMA Preventive Controls for Human Foods (PCHF) regulation contains updated food “Good Manufacturing Practices (cGMPs) that are in many cases made a requirement in a state’s medical or recreational cannabis laws. These cGMPs can be found in 21 CFR 117 Subpart B.

It is imperative that cannabis manufacturers have a number of controls in place including management of suppliers providing the raw material.Food safety risks in cannabis processing could originate from bacteria, cleaning or agricultural chemicals, food allergens or small pieces of wood, glass or metal. The hazards that must be addressed could be natural, unintentionally introduced, or even intentionally introduced for economic benefit, and all must be controlled.

It is unlikely that high heat, used in other food products to remove bad bacteria would be used in the processing of cannabis as many of its desirable compounds are volatile and would dissipate under heating conditions. Therefore, any heat treatment needs to be carefully evaluated for effectiveness in killing bacterial pathogens while not damaging the valuable constituents of cannabis. Even when products are heated above temperatures that eliminate pathogens, if the raw materials are stored in a manner that permits mold growth, mycotoxins produced by molds that have been linked to cancer could be present, even after cooking the product. Storage of raw materials might require humidity controls to minimize the risk of mold. Also, pesticides and herbicides applied during the growth and harvesting of cannabis would be very difficult to remove during processing.

It is imperative that cannabis manufacturers have a number of controls in place including management of suppliers providing the raw material. Other controls that must be implemented include proper cannabis storage, handling and processing as well as food allergen control, and equipment/facility cleaning and sanitation practices. Processing facilities must adhere to Good Manufacturing Practices (GMP’s) for food processing, including controls such as employee hand washing and clothing (captive wear, hair nets, beard nets, removal of jewelry, and foot wear) that might contribute to contamination. A Pest Control plan must be implemented to prevent fecal and pathogen contamination from vermin such as rodents, insects, or birds.

Processing facilities must be designed for proper floor drainage to prevent standing water. Processing air should be properly filtered with airflow into the cannabis processing facility resulting in a slightly higher pressure than the surrounding air pressure, from the clean process area outwards. Toilet facilities with hand washing are essential, physically separated from the process areas. Food consumption areas must also be physically separate from processing and bathroom areas and have an available, dedicated hand sink nearby. Employee training and company procedures must be effective in keeping food out of the processing area. Labels and packaging must be stored in an orderly manner and controlled to prevent possible mix-up.Cleaning of the processing equipment is critical to minimize the risk of cross contamination and microbial growth.

Written food safety operational procedures including prerequisite programs, standard operating procedures (SOP’s), etc. must be implemented and monitored to ensure that the preventive controls are performed consistently. This could be manual written logs, electronic computerized data capture, etc., to ensure processes meet or exceed FSMA requirements.

A written corrective action program must be in place to ensure timely response to food safety problems related to cannabis processing problems when they occur and must include a preventive plan to reduce the chance of recurrence. The corrective actions must be documented by written records.

Supply chain controls must be in place. In addition, a full product recall plan is required, in the event that a hazard is identified in the marketplace to provide for timely recall of the contaminated product.

Cleaning of the processing equipment is critical to minimize the risk of cross contamination and microbial growth. The processing equipment must be designed for ease of cleaning with the minimum of disassembly and should conform to food industry standards, such as the 3-A Sanitary Standards, American Meat Institute’s Equipment Standards, the USDA Equipment Requirements, or the Baking Industry Sanitation Standards Committee (BISSC) Sanitation Standards ANSI/ASB/Z50.2-2008.

Serious food borne contaminations have occurred in the food industry, and cannabis processing is just as susceptible to foodborne contamination. These contaminations are not only a risk to consumer health, but they also burden the food processors with significant costs and potential financial liability.

Anyone processing cannabis in any form must be aware of the state regulatory requirements associated with their products and implement food safety programs to ensure a safe, desirable product for their customers.

Multi-analyte Configuration for Cannabis Testing Services

Managing Cannabis Testing Lab Workflows using LIMS

Multi-analyte Configuration for Cannabis Testing Services

With the state led legalization of both adult recreational and medical cannabis, there is a need for comprehensive and reliable analytical testing to ensure consumer safety and drug potency. Cannabis-testing laboratories receive high volumes of test requests from cannabis cultivators for testing quantitative and qualitative aspects of the plant. The testing market is growing as more states bring in stricter enforcement policies on testing. As the number of testing labs grow, it is anticipated that the laboratories that are now servicing other markets, including high throughput contract labs, will cross into cannabis testing as regulations free up. As the volume of tests each lab performs increases, the need for laboratories to make effective use of time and resource management, such as ensuring accurate and quick results, reports, regulatory compliance, quality assurance and many other aspects of data management becomes vital in staying competitive.

Cannabis Testing Workflows

To be commercially competitive, testing labs offer a comprehensive range of testing services. These services are available for both the medical and recreational cannabis markets, including:

  • Detection and quantification of both acid and neutral forms of cannabinoids
  • Screening for pesticide levels
  • Monitoring water activity to indicate the possibility of microbiological contamination
  • Moisture content measurements
  • Terpene profiling
  • Residual solvents and heavy metal testing
  • Fungi, molds, mycotoxin testing and many more

Although the testing workflows differ for each test, here is a basic overview of the operations carried out in a cannabis-testing lab:

  1. Cannabis samples are received.
  2. The samples are processed using techniques such as grinding and homogenization. This may be followed by extraction, filtration and evaporation.
  3. A few samples will be isolated and concentrated by dissolving in solvents, while others may be derivatized using HPLC or GC reagents
  4. The processed samples are then subjected to chromatographic separation using techniques such as HPLC, UHPLC, GC and GC-MS.
  5. The separated components are then analyzed and identified for qualitative and quantitative analysis based on specialized standards and certified reference materials.
  6. The quantified analytical data will be exported from the instruments and compiled with the corresponding sample data.
  7. The test results are organized and reviewed by the lab personnel.
  8. The finalized test results are reported in a compliant format and released to the client.

In order to ensure that cannabis testing laboratories function reliably, they are obliged to follow and execute certain organizational and regulatory protocols throughout the testing process. These involve critical factors that determine the accuracy of testing services of a laboratory.

Factors Critical to a Cannabis Testing Laboratory 

  • Accreditations & Regulatory Compliance: Cannabis testing laboratories are subject to regulatory compliance requirements, accreditation standards, laboratory practices and policies at the state level. A standard that most cannabis testing labs comply to is ISO 17025, which sets the requirements of quality standards in testing laboratories. Accreditation to this standard represents the determination of competence by an independent third party referred to as the “Accreditation Body”. Accreditation ensures that laboratories are adhering to their methods. These testing facilities have mandatory participation in proficiency tests regularly in order to maintain accreditation.
  • Quality Assurance, Standards & Proficiency Testing: Quality assurance is in part achieved by implementing standard test methods that have been thoroughly validated. When standard methods are not available, the laboratory must validate their own methods. In addition to using valid and appropriate methods, accredited laboratories are also required to participate in appropriate and commercially available Proficiency Test Program or Inter-Laboratory Comparison Study. Both PT and ILC Programs provide laboratories with some measure of their analytic performance and compare that performance with other participating laboratories.

    CloudLIMS Cannabis Testing LIMS: Multi-analyte Configuration for Cannabis Testing Services
  • Real-time Collaboration: Testing facilities generate metadata such as data derived from cannabis samples and infused products. The testing status and test results are best served for compliance and accessibility when integrated and stored on a centralized platform. This helps in timely data sharing and facilitates informed decision making, effective cooperation and relationships between cannabis testing facilities and growers. This platform is imperative for laboratories that have grown to high volume throughput where opportunities for errors exist. By matching test results to samples, this platform ensures consistent sample tracking and traceability. Finally, the platform is designed to provide immediate, real-time reporting to individual state or other regulatory bodies.
  • Personnel Management: Skilled scientific staff in cannabis-testing laboratories are required to oversee testing activities. Staff should have experience in analytical chromatography instruments such as HPLC and GC-MS. Since samples are often used for multi-analytes such as terpenes, cannabinoids, pesticides etc., the process often involves transferring samples and tests from one person to another within the testing facility. A chain of custody (CoC) is required to ensure traceability and ‘ownership’ for each person involved in the workflow.

LIMS for Laboratory Automation

Gathering, organizing and controlling laboratory-testing data can be time-consuming, labor-intensive and challenging for cannabis testing laboratories. Using spreadsheets and paper methods for this purpose is error-prone, makes data retrieval difficult and does not allow laboratories to easily adhere to regulatory guidelines. Manual systems are cumbersome, costly and lack efficiency. One way to meet this challenge is to switch to automated solutions that eliminate many of the mundane tasks that utilize valuable human resources.. Laboratory automation transforms the data management processes and as a result, improves the quality of services and provides faster turnaround time with significant cost savings. Automating the data management protocol will improve the quality of accountability, improve technical efficiency, and improve fiscal resources.

Real Time Test Status in CloudLIMS

A Laboratory Information Management System (LIMS) is a software tool for testing labs that aids efficient data management. A LIMS organizes, manages and communicates all laboratory test data and related information, such as sample and associated metadata, tests, Standard Operating Procedures (SOPs), test reports, and invoices. It also enables fully automated data exchange between instruments such as HPLCs, GC-FIDs, etc. to one consolidated location, thereby reducing transcription errors.

How LIMS Helps Cannabis Testing Labs

LIMS are much more capable than spreadsheets and paper-based tools for streamlining the analytical and operational lab activities and enhances the productivity and quality by eliminating manual data entry. Cloud-enabled LIMS systems such as CloudLIMS are often low in the total cost of acquisition, do not require IT staff and are scalable to help meet the ever changing business and regulatory compliance needs. Some of the key benefits of LIMS for automating a cannabis-testing laboratory are illustrated below [Table 1]:

For about a month now, California’s adult use market has been open for business and the market is booming. About thirty days into the world’s largest adult use market launch, we are beginning to see side effects of the growing pains that come with adjusting the massive industry.

Consumers are also feeling sticker shock as the new taxes add up to a 40% increase in price.While the regulatory and licensing roll out has been relatively smooth, some municipalities are slower than others in welcoming the adult use cannabis industry. It took Los Angeles weeks longer than other counties to begin licensing dispensaries. Meanwhile, retailers in San Diego say the first month brought a huge influx of customers, challenging their abilities to meet higher-than-expected demand.

Businesses are struggling to deal with large amounts of cash, but California State Treasurer John Chiang may have a solution in store. Yesterday, his department announced they are planning to create a taxpayer-backed bank for cannabis businesses.

Reports of possible supply shortages are irking some businesses, fearing that the state hasn’t licensed enough growers and distributors to handle the high demand. Consumers are also feeling sticker shock as the new taxes add up to a 40% increase in price.

In the regulatory realm, some are concerned that a loophole in the rules allows bigger cultivation operations to squeeze out the competition from smaller businesses. The California Growers Association filed a lawsuit against the California Department of Food and Agriculture to try and close this loophole, hoping to give smaller cultivators a leg up before bigger companies can dominate the market.

The Bureau of Cannabis Control (known as just “The Bureau”) began holding meetings and workshops to help cannabis businesses get acquainted with the new rules. Public licensing workshops in Irvine and San Diego held last week were designed to focus on information required for licensing and resources for planning. The Bureau also held their first cannabis advisory committee meeting, as well as announcing new subcommittees and an input survey to help the Bureau better meet business needs.

On the lab-testing front, the state has phased in cannabinoids, moisture content, residual solvent, pesticide, microbial impurities and homogeneity testing. On July 1, the state will phase in additional residual solvent and pesticide testing in addition to foreign material testing. At the end of 2018, they plan on requiring terpenoids, mycotoxins, heavy metals and water activity testing as well.

Colorado Issues Recall, Pesticides Found In Cannabis

Last week, the Colorado Department of Revenue (DOR), the Colorado Department of Agriculture (CDA) and the Colorado Department of Public Health and Environment (CDPHE) announced a health and safety advisory for a large number of cannabis products grown and produced by Tree of Wellness Inc., doing business as Tree of Wellness. The health and safety advisory, synonymous with a product recall, was issued due to the detection of off-label pesticides in cannabis grown by Tree of Wellness.

Tests found Myclobutanil present in batches going all the way back to May, 2017, with some contaminated batches as recent as late October.

According to the press release, the CDA confirmed the presence of Myclobutanil, a near-ubiquitous fungicide used in a wide range of agricultural practices. The chemical has been a thorn in the side of the cannabis industry for being used off-label, or inappropriately, on cultivating cannabis.

Here are the batch numbers included in the recall

Myclobutanil is the active ingredient in Eagle 20, a pesticide used frequently in other agricultural fields like grapes, apples and spinach. According to UC Davis professor and Steep Hill scientist Dr. Don Land, Myclobutanil becomes significantly more dangerous when heated, or smoked. That chemical reaction produces hydrogen cyanide, an extraordinarily toxic chemical. Because of this, and the lack of research on what happens when these chemicals are burned or heated, there is a growing public concern that cannabis laced with a chemical like Myclobutanil can cause adverse health reactions.

The public health and safety advisory says they detected Myclobutanil in cannabis flower, trim, concentrates, and infused-products from Tree of Wellness. The CDPHE and DOR recommend consumers that have the affected products return them to where they were purchased for proper disposal.

Consumers in Colorado should check their labels to see if their products fall under the recall. Look for the Medical Optional Premises Cultivation License 403-00664 and/or Medical Marijuana Center License 402-00443. The recall includes batches of 23 different strains grown by Tree of Wellness.

According to a press release issued on Friday, September 22nd, the Colorado Department of Public Health and Environment (CDPHE), along with the Colorado Department of Revenue (DOR) and the Colorado Department of Agriculture (CDA), issued a public health and safety advisory for cannabis products tainted with pesticide residue.

The advisory was issued after the detection of pesticide residues on retail cannabis plant material and products with cannabis grown by RK Enterprises LTD, doing business as Rocky Mountain Remedies. The CDA confirmed that they detected the pesticide, Avermectin, an insecticide with a relatively high acute toxicity.

When pesticides like this are not on the list approved for use in cannabis cultivation, it is considered an off-label use. According to the press release, some of the products affected include flower, trim, concentrates and infused-products.

Consumers are advised to look at the label of their products and check to see if it matches the license number 403R-00180 and harvest batch numbers r206goldenkush9.11.17 and m206larryog9.11.17. Consumers are told to either dispose of the product properly or bring it back to the retail store where they purchased it.
