The Canadian Food Inspection Agency has issued a recall for Enoki mushrooms distributed by WK Produce due to a possible Listeria contamination.
The product was sold in 150-gram packages in British Columbia, Alberta and Ontario and may also have been distributed nationally.
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 but can still make you sick.
Symptoms can include vomiting, nausea, persistent fever, muscle aches, severe headache and neck stiffness.
