*NEW* Total Aerobic Count (TAC)
Total Aerobic Count
Still, many cannabis regulators require cannabis samples pass TAC testing before they can be sold in dispensaries. The most current version of the Cannabis Inflorescence and Leaf monograph published by the American Herbal Pharmacopoeia, which many states use to determine pass or fail criteria for microbial testing, recommends less than 100,000 CFU/g on cannabis plant material and 10,000 CFU/g on extracts.
Who requires TAC testing on cannabis?
- New Hampshire
- New Mexico
- North Dakota
- Rhode Island
*Only required for select matrices, view MGC’s Cannabis Microbial Testing Regulations by State page for more information
Why Use qPCR for TAC testing on Cannabis?
Peer-reviewed studies have shown that qPCR testing methods are able to more accurately detect and quantify bacteria species present on a cannabis sample than culture-based methods. The Total Aerobic Count test looks for a specific DNA sequence that exists in all aerobic bacteria. Because of this, the Total Aerobic Count test can detect all aerobic species, regardless of whether they grow in culture. Culture-based tests can only detect the species that grow in a given medium and timeframe. Conversely, qPCR can more effectively exclude off-target microbial species, such as yeasts and molds, which have been shown to grow in TAC culture medium.
Test for TAC with Confidence
We can test for Total Yeast and Mold in a variety of cannabis matrices. The PathoSEEK® Platform is the only method designed for and validated on cannabis flower, extracts, and a variety of infused products. We proudly partner with Medicinal Genomics to provide several of our validated cannabis testing services.
We’e developed a simple method to collect microbal DNA samples from your plants. This enables anyone in the world to take advantage of our services because our kits produce a purified DNA sample which is 100% legal to mail. All you need are the same materials (tweezers, alcohol, etc) required for any of our other tests. If you would like to test something other than plant material please contact us before placing your order.
All testing is offered for research purposes only and not valid for regulatory certification.
