Canada's food watchdog says certain Les Fumet Sylvestre dried and smoked duck products may be tainted with bacterium listeria monocytogenes.

Ste-Marguerite-based manufacturer Les Fumet Sylvestre is recalling the products, which were distributed in Quebec, from the marketplace.

The recall applies to the Dried and Smoked Duck Magret sold in 56 g packages with the UPC code 6 96437 40423 0 and the lot code 270 10.

Foods contaminated with Listeria monocytogenes may not appear or smell spoiled but may cause listeriosis, the agency said.

Symptoms include high fever, severe headache, neck stiffness and nausea. Pregnant women, the elderly and people with compromised immune systems are particularly vulnerable.

Listeria monocytogenes can be found in dairy products, vegetables, fish and meat products. The bacterium can be spread by contact with a contaminated product or during food preparation.

No associated illnesses have been reported.
