TORONTO – The Public Health Agency of Canada (PHAC) says it is investigating an outbreak of human illness linked to Listeria-contaminated chicken products.

In a public notice updated Wednesday, the PHAC says the outbreak of Listeria infections is likely linked to Rosemount brand cooked and diced chicken products.

The agency says there have been seven confirmed cases of Listeria illness in three provinces; one in British Columbia, one in Manitoba and five in Ontario.

Six people have been hospitalized and the PHAC says the affected individuals are between 51-97 years-old, and mostly female.

“The collaborative outbreak investigation was initiated because of an increase of Listeria illnesses that were reported in June 2019. Through the use of a laboratory method called whole genome sequencing, two Listeria illnesses from November 2017 were identified to have the same genetic strain as the illnesses that occurred between April and June 2019,” the public health notice says.

The PHAC says the U.S. Center for Disease Control (CDC) is also investigating a Listeria outbreak in several states, and the type of Listeria affecting the U.S. is genetically similar to one believed to be making people ill in Canada. The CDC and the PHAC are collaborating on the ongoing investigation.

The Canadian Food Inspection Agency (CFIA) first issued a food-recall warning for Rosemount brand cooked chicken meat on August 18, and has since issued six separate food-recall warnings Tuesday and Wednesday over chicken products distributed across Canada due to concerns of Listeria contamination.

Listeria monocytogene infections can have symptoms of vomiting, nausea, persistent fever, muscle aches, severe headache and neck stiffness.

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