The BC Centre for Disease Control has confirmed that the outbreak strain of Listeria has been identified in a resident of Cranbrook, B.C.

The woman, who has an underlying health condition, may have consumed meat contaminated with the bacteria that cause the food-borne illness Listeriosis.

She contracted the disease prior to the Canada-wide recall of certain Maple Leaf products.

A second case of Listeria in a Cranbrook resident from May has shown not to be a match to the current outbreak Listeria strain, the BC Centre for Disease Control said.

There were already three confirmed cases in the province.

A patient who died on Vancouver Island had the outbreak strain, but the cause of death is still under investigation.

However, federal officials acknowledge Listeria contributed to that death.

Last week, the Canadian Food Inspection Agency (CFIA) issued a recall of some ready-to-eat deli meats that may be contaminated with Listeria monocytogenes, the bacteria that cause the Listeriosis

Listeria Monocytogenes bacteria is common in the environment. "Most people exposed to the bacteria will not get sick," adds Dr. Rob Parker, Medical Health Officer with Interior Health

"Those most at risk for developing infection are seniors and the elderly, those with weakened immune systems, pregnant women and newborns."

Health officials now say 12 deaths have been linked to a listeriosis outbreak from a Maple Leaf Foods plant. But it's unclear what exact role the bacteria may have had in six of those deaths.
