Total Aerobic Count (TAC)
Total Aerobic Count
Still, many cannabis regulators require cannabis samples pass TAC testing before they can be sold in dispensaries. Many states use pass or fail criteria for microbial testing, recommending less than 100,000 CFU/g on cannabis plant material and 10,000 CFU/g on extracts. It is up to you to determine the current local regulations in your area.

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.
We developed a simple method to collect microbial 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.
