Another person has died from listeriosis linked to tainted meat processed at the Maple Leaf Foods plant in Toronto.

Officials will only say the 15th victim was a resident of Ontario.

Thirteen people in total from Ontario have died from listeriosis, and there's one each in Alberta and British Columbia.

Another death in New Brunswick has not been conclusively linked to meats recalled by Maple Leaf Foods.

In total, there have been 42 confirmed listeriosis cases linked to the outbreak in Canada.

One person has died in Quebec from listeriosis contracted by eating cheese. Last week, the Quebec government ordered the recall of 11 cheeses.

Maple Leaf says the most likely cause of the outbreak associated with its products was bacteria embedded deep inside meat slicing equipment at the plant.

The slicers are made by Illinois-based Formax, which says there are almost 300 of the machines installed at plants around the world.

Formax says the machines have handled 2.3 billion kilograms of meat over the last 13 years with no incident.

There's no indication when the Maple Leaf meat plant in Toronto will be allowed to re-open, after it was closed three weeks ago for disinfection.
