There are currently no viable treatment options available for Hop Latent Viroid (HLVd) infected cannabis plants. Meristem tissue culture can be used to rescue infected plants, but the process can [...]

We continue to see several conflations and misconceptions voiced in the discussion about microbial safety standards for cannabis products. The foundation for these misconceptions is the idea that [...]

The State of Michigan is in the process of scrutinizing molecular methods and culture based methods for the detection of Total Yeast and Mold (TYM) on cannabis. They chose to run this study on [...]

30 live organisms were ordered from ATCC and tested for inclusion and exclusion testing on our TYM and TAC. All bacteria are positive for TAC and negative for TYM. 30 live organisms (fungal) were [...]

In 2019, AOAC developed an SMPR for Aspergillus, E.coli, Salmonella detection on cannabis. These are three separate SMPRs. AOAC does not have an official SMPR for TYM but we can take what we have [...]

In 2020, a Michigan lab contacted us claiming our CFU/cq calculations were not matching their samples, nor did they match a recently released Candida albicans NSI Total Yeast and Mold (TYM) [...]

In 2015 we published a microbiome survey of medicinal cannabis flowers. We followed up this study with another publication in 2016 in the open access and open peer review platform F1000. Both of [...]

Cannabis testing labs are being presented with a wide variety of microbial testing solutions, each claiming they can shorten test times, increase sensitivity, and lower costs. Given microbial [...]
