Denver-based Bonsai Cultivation has voluntarily recalled a series of cannabis products for elevated levels of mold and yeast.

The recalled cannabis was sold throughout Colorado and affects as many as 144 dispensaries in the state, which sold the marijuana prior to Oct. 14. The recall also affects three cultivation facilities in Colorado and 11 manufacturing facilities in the state.

The recall was made in conjunction with the Denver Department of Public Health & Environment (DDPHE) for Bonsai Cultivation’s dried marijuana, including flower, shake, trim, and pre-rolls, which were identified to contain potentially unsafe levels of yeast and mold.

The affected cannabis products have an OPC code of 403R-00228. The recalled cannabis has been distributed since April 30. The 144 retail locations were the recalled cannabis was sold can be viewed here.

Consumers or business that have purchased the recalled cannabis should dispose of the products or return them to the place of purchase.

Questions about the cannabis recall can be directed to Bonsai Cultivation at voluntaryrecall@bonsaicultivation.com or DDPHE, Public Health Investigations Division at phicomments@denvergov.org or 720-913-1311.

According to the DDPHE, high levels of mold or yeast in cannabis can cause health impacts through inhalation that are dependent on the specific product, duration, frequency, and level of exposure. Consumers that have symptoms of illness from smoking, vaping, or other consumption method of cannabis should contact their healthcare provider as well as the DDPHE at phicomments@denvergov.org.

The DDPHE said in a statement that it “is investigating this issue and overseeing the recall process to remove potentially contaminated products from commercial circulation.
