20 Denver marijuana dispensaries fail mold and yeast tests

Random tests for mold and yeast at more than two dozen Denver-area cannabis dispensaries resulted in 20 stores being ordered to hold or quarantine their cannabis flower, shake or pre-rolled joints.

The Denver Department of Public Health and Environment conducted 25 tests over a two-day period in September, according to alt-weekly newspaper Westword, which analyzed the results.

The failure rate amounted to 80% of the dispensaries that underwent testing.

Denver has hundreds of cannabis retailers. And the random inspections were part of a research project, announced in August, aimed at learning more about the shelf life and packaging of marijuana and did not target specific stores.

Most dispensaries that failed microbial testing got their product from wholesale providers, which were not identified in the reports.

It isn’t clear whether a voluntary recall of marijuana plant-material products issued by Denver-based Bonsai Cultivation is tied to the random inspections.

The Department of Public Health and Environment declined to provide the reports to Marijuana Business Daily because the study was confidential, said Tammy Vigil, manager of media relations.

“We believe the Westword reporter may have invested significant time searching our online database to draw the conclusions he did,” Vigil wrote in an email to MJBizDaily.

    So…it’s okay to say that 80% of the product being sold in CO dispensaries is contaminated w/ mold or yeast. That is hilarious! But keep on beating that drum about how black-market is more dangerous and we all need government oversight and corporate ownership to be safe! I will definitely be citing this article everywhere…

    How company’s cure there bud is not the govs doing! Proper drying, curing and packaging is the responsibility of the the company. Then the company’s that sell it, need to make sure they do a good job preserving the product. If the company’s buy bulk then they need to get that packaged and sealed quickly in a very clean environment. This industry isn’t nearly as easy to contaminate the product as brewing craft beer. That is very very sensitive to contaminants.

    Thanks for sharing. The mold inspector must understand and clearly distinguish between the mold with which the products of the store were created and mold that appears as a result of hidden leaks, etc. I think a special approach is needed here.
