Microbiological Testing

Microbiological contamination testing is required for OMMA compliance to ensure cannabis products are free of bacteria, yeast, mold, and other toxins

Our microbiological team can rapidly screen for microorganisms potentially found in cannabis products through qPCR and genomic screening. All methods are compatible with guidelines set forth by A2LA.

We test for the following species:

Shiga-toxin producing E. Coli (STEC) – STECs are a type of disease-causing bacteria that produces shiga toxin. 

Salmonella spp. – Salmonella is a group of gram-negative, rod shaped bacteria that cause typhoid fever, gastroenteritis, and other illnesses.

Aspergillus spp. – Aspergillus is a type of mold that can cause severe respiratory infection, especially in those with compromised immune systems. The State of Oklahoma chosen to test for four different pathogenic species of Aspergillus that are known to be found in cannabis.

These six species include:

  • Aspergillus flavus
  • Aspergillus fumigatus
  • Aspergillus niger
  • Aspergillus terreus
  • Salmonella Spp.
  • Shiga toxin-producing Escherichia
