The Michigan Regulatory Agency issued a recall Aug. 6 for nearly 3,200 pre-rolls processed in a Bay City facility after a processing plant employee was accused of licking the product, according to an MLive.com report.

Although it’s unclear how regulators learned of the allegations, the Michigan Regulatory Agency told the news outlet that the processing plant employee “licked a pre-roll marijuana product while making the product.”

The owners of the processing facility also operate Dispo, a medical and adult-use dispensary located in Bay City, according to MLive.com, and the processing license has been suspended for 14 days due to the incident.

The recall includes various brands, and the affected pre-rolls were sold through medical and adult-use retailers in Bay City, Hazel Park, Detroit, Traverse City, Ann Arbor, Lansing, River Rouge, Ferndale, Quincy, Lowell, Negaunee and Lapeer, the news outlet reported. Sales of the recalled product took place between June and Aug. 3.

The Michigan Regulatory Agency has indicated that consumers should return affected products to the retailer where they were purchased so they can be disposed of, and dispensaries must notify customers who purchased recalled products, MLive.com reported.

State officials told the news outlet that an ongoing investigation began July 31, and the processor has agreed to halt its operations until it receives further instructions from regulators.
