Several people in Ontario have become sick with listeriosis in an outbreak that triggered a national recall of certain plant-based milks that may have been contaminated with Listeria.
What is listeria?
The Listeria bacterium is found in soil, sewage and untreated water. It can also be found in foods such as meat, seafood, fruits, vegetables and dairy products.
How does the bacterium get into food?
Listeria can get into fruits and vegetables if contaminated water is used on crops. They can also become contaminated from Listeria in soil and manure-based fertilizers.
Food manufacturing and processing facilities can also spread the bacteria if contaminated water or contaminated ingredients are used there, Health Canada says.
McMaster University microbiologist Lori Burrows says Listeria can also get into food or liquids if surfaces or equipment in processing plants aren’t sufficiently disinfected.
What is listeriosis?
Listeriosis is an illness caused by consumption of Listeria-contaminated food or water.
It can also be passed from mother to baby during pregnancy.
