Yeast & mold are fungi that can contaminate cannabis, affecting its safety and quality.
Also called / Category:
Yeasts and molds / Lab Testing & QA/QC
Key takeaways:
- Yeast & mold can spoil cannabis, leading to health risks.
- Testing for yeast & mold is part of quality assurance in cannabis production.
- High levels of these fungi indicate poor storage or cultivation practices.
What it is / How it shows up:
Yeast & mold are common terms in cannabis quality testing, often seen on Certificates of Analysis (COA). These fungi thrive in moist environments and can grow on cannabis plants if not properly dried and cured. The presence of yeast & mold in cannabis can indicate improper handling or storage conditions. Consumers rely on lab testing to confirm that cannabis products are free from these contaminants, ensuring a safe consumption experience. In Canada, regulations require cannabis to undergo rigorous testing to ensure low levels of yeast & mold, contributing to consumer safety.
How it’s measured or identified:
- Lab tests measure colony-forming units (CFUs) per gram.
- Microbiological assays identify specific strains of yeast & mold.
- Testing ensures compliance with health regulations.
Use in context:
- "This batch failed the yeast & mold test, so it can't be sold."
- "Ensure your storage area is dry to prevent mold."
- "Our products are tested for yeast & mold to guarantee quality."
Safety & compliance in Canada:
