The listeria outbreak has sickened more than a dozen people and resulted in one confirmed fatality. Health officials are investigating other deaths to see if they are linked to the outbreak and more related illnesses are anticipated, officials have indicated.


“We are yet to confirm the source of the outbreak and the investigation is ongoing,” a CFIA official told just-food. “We are advising consumers to avoid pre-cooked deli meats. Other high-risk foods are soft cheese, pâtés and smoked fish or meats.”


It is believed that the probable source of the outbreak is deli meat manufactured at Maple Leaf’s factory in Toronto. Listeria monocytogenes has been detected in two Maple Leaf products. However, testing has not confirmed that it is the same strain that caused the outbreak.


Maple Leaf has recalled all products made on the same production lines as the contaminated products since June and temporarily closed the facility as a “precautionary measure”, the company said.
