An Italian-made cheese sold in Canada has been recalled over concerns it may be contaminated with listeria.

Mauri-brand Gorgonzola cheese has been sold in Alberta, New Brunswick, Nova Scotia, Ontario and Quebec, said the Canadian Food Inspection Agency.

Its importer, Arla Foods in Concord, Ont., is voluntarily recalling the product, which has the code L. 3100012 on its packaging and a best before date of Jan. 7, 2013.

Food contaminated with the bacteria listeria may not spell or look spoiled. Eating food tainted with the bacteria can cause listeriosis, which can lead to high fever, severe headaches, neck stiffness, nausea or death.

A 2008 listeria outbreak -- largely connected to sandwich meats -- infected hundreds of people in Canada and killed 22.

Pregnant women, the elderly and people with weakened immune systems are particularly at risk.

There have been no reported illnesses associated with the Gorgonzola recall.
