Marijuana packages sold at several Michigan dispensaries have been recalled due to chemical contamination at a processing facility.
The Michigan Marijuana Regulatory Agency said several batches of marijuana from Kalkaska-based Glo contained residues of the banned chemicals bifenthrin and chlorfenapyr.
Officials said the batches were run through a mechanical trimmer contaminated with those chemicals.
The voluntary recall affects packages of bud, pre-packaged buds and pre-rolls sold during select intervals from late August through early September.
The agency advised consumers who purchased the products in question to return them to the seller for proper disposal.
The products were sold at dispensaries in Cheboygan, Manistee, Grand Rapids and Kalamazoo.
