Listeria Outbreak Linked to Plant-Based Milk Alternatives in Canada Results in Two Deaths

The implicated products, which include varieties made from almonds, oats, coconuts, and cashews, were sold under the Silk and Great Value brands, prompting a nationwide recall last week.

Silk, a subsidiary of the French multinational Danone, reported that the contaminated products were manufactured at a third-party facility in Ontario. Danone has stated that production at this plant will remain halted pending an investigation into the source of the contamination. Importantly, the affected products were not distributed outside of Canada.

Health Canada has reported a total of 12 cases of listeria infection—10 in Ontario, one in Quebec, and one in Nova Scotia—with the majority of cases involving women over the age of 60. The time frame for these illnesses stretches from August 2023 to July 2024, with Health Canada cautioning that additional cases may still be reported.

Symptoms of listeriosis can surface as soon as three days after consuming contaminated food, though more severe manifestations, such as meningitis and blood poisoning, may not appear until up to 70 days post-exposure. This infection is particularly dangerous for individuals with weakened immune systems, older adults, and pregnant women, with unborn and newborn babies also being highly susceptible to severe outcomes.

In light of these events, Health Canada has advised Canadians to check their homes for any products listed in the recall, noting that contaminated products may not necessarily exhibit any visible signs or odors of spoilage. The ongoing investigation aims to prevent further cases and ensure public safety by identifying and addressing the source of the listeria contamination.
