Agency clumsily flags products from “500-plus failed yeast and mold tests”
On Wednesday, the Massachusetts Cannabis Control Commission issued a “public health and safety advisory due to the identification of contaminated and potentially contaminated Marijuana flower and Marijuana Products that were tested between April 1, 2024 and April 15, 2025 and noted in the Summary Suspension Order (SSO) issued on June 30, 2025.”
In the referenced SSO, the agency “identified 544 lab samples that previously failed Total Yeast and Mold testing.” The CCC suspended the Independent Testing Lab allegedly responsible for those failures, but until now had not elaborated on the fate of the affected products. In the interim, the agency was sued by said lab which argues that it was denied “its basic due process rights of notice and opportunity to be heard.”
As for what those test results and/or the new public advisory actually mean for Mass cannabis buyers … It’s hard to tell. From this week’s CCC notice: “Consumers and Patients are urged to check the labels of any adult- or medical-use Marijuana and Marijuana Products in their possession to determine whether those products were tested during the relevant period … If so, please refer to the Commission’s Public Health and Safety Advisories portal for more information about impacted Metrc Package Tag/Batch numbers.”
In other words, it’s up to you to figure out if your weed was contaminated. The CCC is hardly here to help; like with its February announcement along similarly vague lines, the agency revealed little in this latest half-step. We simply learned that regulators report having “taken steps to prevent further sales of the contaminated and potentially contaminated products through Metrc, a third-party regulatory cannabis system to track every plant from seed to sale in Massachusetts.”
As for the products themselves, which regulators presumably do not recommend for consumption but which haven’t quite been recalled, it’s unclear what some of them even are. It takes a digital Magellan to navigate the footnotes and links in the announcement. The actual data set tells a much different story than the CCC announcement that simply notes “544 lab samples that previously failed Total Yeast and Mold testing.” The compendium of products that were potentially contaminated has more than 7,600 listings, items from dozens of cultivators of various sizes.
For those who do manage to crack the code, “Consumers and Patients that possess any of the affected products may destroy them or return them to the licensee where they were purchased for disposal and/or contact them for more information.”
