Hundreds of frozen waffle products — including many on Canadian store shelves — are being recalled by the U.S. manufacturer because of the risk of listeria contamination.

In Canada, the waffles are sold under various brands including Great Value, Compliments, No Name and others.

TreeHouse Foods, Inc. said in a statement that it is “voluntarily recalling certain frozen waffle products” due to possible Listeria monocytogenes contamination..

“Listeria monocytogenes is an organism that can cause serious and sometimes fatal infections in young children, the frail or elderly, and others with weakened immune systems,” the company said in a statement.

“Healthy individuals may only experience short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea. Infection with Listeria monocytogenes can cause miscarriages and stillbirths in pregnant women.”

To date, there have been no reports of illnesses associated with the recalled products. According to the company, the problem was discovered through routine testing at the production facility.

However, people are urged to check their freezers for the recalled waffles and either throw them away or return them for store credit at the store where they purchased them.
