Test Benefits

Microorganisms found in cannabis products have the potential to be very harmful when consumed or inhaled. Aspergillus species cause respiratory infections, while Shiga-toxin producing E. coli and several species of Salmonella can cause gastroenteritis and diarrhea. We utilize quantitative polymerase chain reaction (qPCR) to screen for the presence of these fungi and bacteria to ensure your products are clean and safe. Our microbiological testing methods can detect specific species of organisms and significantly reduce false positive results compared to traditional plating methods.

What We Test For

Regulation

Microbial Impurities Testing

  1. The laboratory shall analyzes a sample of cannabis or cannabis product to determine whether microbial impurities are present.

  2. The laboratory reports the result of the microbial impurities testing by indicating “pass” or “fail” on the COA.

  3. Depending on the type of product being analyzed, the following conditions may be tested and reported by the lab:

    1. The detection of Shiga toxin-producing Escherichia Coli in one gram of sample;
    2. The detection of Salmonella spp. in one gram of sample; and
    3. The detection of Pathogenic Aspergillus species A. fumigatus, A. flavus, A. niger, and A. terreus in one gram of sample.
  4. If a sample fails microbial impurities testing, the batch from which the sample was collected fails microbial impurities testing and canot be released for retail sale.
