Health Canada has recently recalled a specific batch of recreational cannabis due to microbial contamination. This action highlights the importance of stringent cannabis quality controls and adhering to state guidelines on hemp testing to avoid costly recalls.
Recent Recall Underscores Testing Necessity
The contaminated cannabis, produced by a Alberta-based company was identified through Health Canada's random testing program. This initiative, started in 2023, aims to uphold product safety by regularly analyzing samples from licensed retailers.
The recall affected approximately 1,200 packages, each containing 28 grams, distributed in British Columbia and packaged in September 2023. The microbial contamination found in these packages surpassed the regulatory limits for yeast, mold, and bacteria, prompting immediate action from the authorities.
Recalls of this nature are relatively rare in Canada, where most cannabis recalls have traditionally been due to issues with product labeling.
The Vital Role of State Testing Guidelines
As the cannabis industry continues to expand, the implementation of state guidelines for hemp testing becomes even more crucial. These guidelines generally include a series of comprehensive tests designed to evaluate the safety and potency of cannabis products:
Cannabinoid Potency Tests: focus primarily on THC, CBD, and CBN levels. Two primary methods are utilized for this testing: High-Performance Liquid Chromatography (HPLC) and Gas Chromatography (GC). HPLC is preferred for its ability to measure cannabinoids separately without the need for heat, which is particularly important for products consumed without heating, like edibles.
Terpene Analysis: analyze terpenes due to their therapeutic properties and influence on the flavor and aroma profiles of cannabis. Advanced methods like the full evaporation technique (FET)-headspace (HS)-GC-FID are used for effective profiling.
Residual Solvents Testing: ensures that solvents used in the extraction processes are completely removed from the final product. Techniques like FET-HS-GC-FID and GC/MS are employed for efficient analysis.
Pesticide Detection: detect pesticide residues used in cultivation with analytical techniques such as GC-MS/MS and HPLC-MS/MS.
Heavy Metal Screening: test for metals like arsenic, lead, and mercury absorbed from contaminated soils by the cannabis plants. Methods such as inductively coupled plasma-mass spectrometry (ICP-MS) are used due to their sensitivity and accuracy in detecting trace amounts of these contaminants.
Microbial Contamination Tests: test for pathogenic bacteria and fungi, including species that produce toxins like mycotoxins and aflatoxins. Techniques such as quantitative polymerase chain reaction (qPCR) and culturing on selective media.
By ensuring adherence to rigorous testing protocols and managing operational costs effectively, laboratories can not only comply with legal standards but also enhance consumer trust and safety in the rapidly growing cannabis market.
Enhancing Lab Efficiency and Cost Management
For laboratories conducting cannabis testing or product research and development, managing costs is also crucial. Systems like the Yamato water purification system can dramatically reduce the total cost of ownership, potentially saving up to 50% compared to other systems. This is particularly beneficial for applications like HPLC, which require significant amounts of ultra-pure water.
Filter cartridges for the Yamato system are twice as big as other brands, saving you even more lab budget.
