Licensed medical cannabis producer Mettrum announced a recall of their product, in a press release sent out earlier today.

Mettrum said the recall was due to a foliar spray, purchased from the third party supplier, used to wash plants which, after review by Health Canada was found to contain an ingredient called pyrethrin. Pyrethrin is used as an insecticide on crops in Canada, but is not approved for use on medical cannabis.

“Quality, purity and transparency are Mettrum’s top priorities, which is why we have initiated a voluntary recall of the exposed product and are reaching out directly to all impacted clients,” said Mettrum Health Corp director and CEO Michael Haines. “While the ingredient is not harmful and there is no negative effect on product quality and safety, we are doing everything possible to ensure client satisfaction and confidence is upheld.”

Mettrum stated that cannabis samples were inspected by third-party testing facilities and no traces of pyrethrin residues were found on growing plants or finished products.

Health Canada classifies this type of recall as “Type III: a situation in which the use of, or exposure to, a product is not likely to cause any adverse health consequences.”

“Clients who have previously purchased affected products are being contacted directly with additional information and next steps,” Mettrum’s release stated.
