As its production rapidly grows, the threat of fungal and bacterial contamination increases as well. Considering that testing can detect any aerobic yeast or mold on your product, limits for all Microbial Contamination tests are fairly strict. Because cannabis is a non-sterile product, careful cultivation and processing must be employed.

Our microbial testing suite examines contaminants of concern following protocols consistent with United States Pharmacopeia (USP) Chapters <61>, <42>, and <561>.

Viridis provides easy to understand results of total viable aerobic bacteria, total yeast and mold, total coliforms, and bile-tolerant gram-negative bacteria are given in colony forming unit (CFU) counts per mass of product sample using aseptic microbial plating techniques.

Strict limits are also set for two pathogenic bacteria, E. Coli and Salmonella. A sample can fail if a single live cell of these bacteria is detected. Viridis uses enzyme-linked immunosorbent assay (ELISA) techniques to ensure your products are tested free of those pathogens.

Mycotoxins (Aflatoxins B1, B2, G1, G2, and Ochratoxin A), which are toxic metabolites produced by fungus, are examined to ensure they do not exceed limits. We provide both a qualitative screen for Aflatoxins and a measure of absolute concentrations using high-performance liquid chromatograph equipped with a variable wavelength detector (HPLC-VWD).

Viridis will work closely with you to help find the root of any failed microbial contamination test.
