Microbial Testing


Microbial Testing is a vital component when it comes to ensuring any major consumer product is free of bacteria and mold that could potentially cause illness or disease. We test for Shiga toxin-producing E.coli (STEC), Salmonella, and pathogenic Aspergillus species, all required under BCC regulations (pg 122).


How We Test for Microbial Growth


We use methods that involve quantitative polymerase chain reactions (qPCR) to determine the presence of harmful microbes within a sample.




  • STEC E. Coli


  • Salmonella


  • 4 Strains of Aspergillus (A. Flavus, A. Fumigatus, A. Niger, & A. Terreus)


  • Aerobic Bacteria


  • Yeast and Mold


If a microbe you'd wish to have analyzed doesn’t fall into one of these categories, let us know and we can provide you a solution.



All R&D results are unofficial. For information on certified testing please call the lab at (858) 623-2740.

We currently follow activity levels based on the 2018 California Cannabis Regulations. To view these, visit our 2018 CA Testing Regulations page.




Currently we have five testing focuses: potency, terpenes, residual solvents, microbials, and pesticides, but are willing to look into new categories that arise. Our goal is to raise the cannabis testing standards to a level at which the cannabis community can trust...

The term Cannabinoids originally referred to a class of oxygen containing aromatic compounds which contained 21 carbons that were produced by Cannabis sativa. Now cannabinoids have a broader definition referred to as phytocannabinoids...

Because pesticides are used in the cultivation of cannabis, they need to be tested for in flower, trim, and extracts. When flower or trim is extracted for cannabinoids and terpenes, the pesticides are extracted and concentrated as well. When this happens it leads to...

Terpenes are naturally occurring small organic molecules that are produced from plants. Terpenes are what makes plants smell a certain way, which is then extracted and sold as essential oils. In cannabis over 100 terpenes have been detected which give them their unique smell and taste...

Residual solvent testing is used to ensure that the cannabis products are safe to consume. Cannabis flower extraction of cannabinoids and terpenes is a very common method these days, so the need for residual...
