Ontario’s top doctor says nine people in the province have become sick with listeriosis and five have been hospitalized in an outbreak that triggered a national recall of certain plant-based milks.

While the cases reported so far are all in Ontario, the Canadian Food Inspection Agency is urging people across the country not to drink Silk oat, almond, coconut or almond and cashew milk and Great Value almond milk with expiry dates up to and including Oct. 4., as they could be contaminated with Listeria bacteria.
