A possible Listeria contamination has prompted the recall of sliced white mushrooms sold in Ontario and Quebec and possibly other provinces or territories.

The Canadian Food Inspection Agency says a recall has been issued by Carleton Mushroom for the mushrooms, which were prepared for Metro Brands.

The product was sold in 227-gram packages with a best before date of Oct. 25, 2021.

Customers are being told to either throw the mushrooms out or return them to the store where they were purchased.

There have been no reports of any illnesses linked to the product.

Food contaminated with Listeria may not look or smell spoiled and symptoms can include vomiting, nausea, persistent fever, muscle aches, severe headache and neck stiffness.
