The Missouri Department of Health and Senior Services (DHSS) recently conducted an investigation of a complaint that medical cannabis sold in the state contained mold growth, and has concluded that the product batch is safe for consumption, according to a KY3 report.

Retesting of the product confirmed that the batch falls within acceptable limits for relevant tests, including microbial screening, and presents no health or safety concerns, the news outlet reported.

On Oct. 20, the DHSS notified more than 200 patients who had purchased the product in question that a complaint was being investigated.

“We encourage all patients to alert us to any concerns they have about any product they purchase,” Lyndall Fraker, director of the DHSS Section for Medical Marijuana Regulation, said in a public statement. “If there are concerns, we would advise that they do not consume any of the product until the situation can be properly investigated.”

Missouri’s medical cannabis market launched Oct. 17, when the state’s first dispensary, N’Bliss, opened its doors to patients.
