Microbial count (TPC): A measure of the number of microorganisms present in a cannabis sample, ensuring product safety and quality.
Also called / Category:
Total plate count (TPC) / Lab Testing & QA/QC
Key takeaways:
- Microbial count ensures cannabis safety by checking for harmful microbes.
- TPC includes bacteria, yeast, and mold counts.
- High microbial counts can indicate contamination or poor handling.
- Testing is important for consumer safety and product quality.
What it is / How it shows up:
Microbial count (TPC) is often found on Certificates of Analysis (CoAs) accompanying cannabis products. It indicates the total number of microorganisms, like bacteria or fungi, present in a sample. This count is crucial for ensuring the safety and quality of cannabis products, as excessive microbial presence can result in health hazards. Consumers might see this term when reviewing product lab results to verify safety compliance before purchase. Microbial counts are especially important in the cannabis industry, where product purity directly impacts user safety and regulatory compliance.
How it’s measured or identified:
- Plating techniques to count colonies.
- Automated systems for rapid detection.
- DNA-based methods for specific microbes.
Use in context:
- "The microbial count on this batch was low, indicating good quality control."
- "We ensure our products have a low TPC to meet health standards."
- "A high microbial count can lead to product recalls."
Safety & compliance in Canada:
