Cannabis microbial testing
Cannabis microbiology & microbial safety testing
Cannabis plants and products are not sterile, and a certain level of microbial presence is expected. However, microbial contamination must be carefully monitored and controlled to protect consumer health and meet regulatory requirements under the Cannabis Regulations. Effective microbial testing is essential to identify harmful bacteria, yeasts, and moulds that may pose safety risks.
Key services
Microorganisms are bacteria, yeasts and moulds that are “microscopic” and not typically visible to naked eye. Cannabis plants and products are not sterile, and some microbial contamination is expected; however, there are limits that prevent adverse human health effects. Microbial testing is a requirement under the cannabis regulations for all fresh, dried and oil based cannabis products. We have verified the appropriate compendial EP/USP methods for detection of the following:
- Total aerobic plate count (TAPC)
- Total yeasts and moulds (TYAM)
- Bile tolerant gram negative bacteria (BTGN)
- Escherichia coli
- Salmonella spp
- Pseudomonas aeruginosa (cannabis extracted oils)
- Staphylococcus aureus (cannabis extracted oils)
