Canadian officials confirm outbreak of Listeria infections linked to plant-based beverages

At least nine people have been infected with Listeria monocytogenes in relation to recalled Silk brand almond milk, coconut milk, almond-coconut milk and oat milk, as well as Great Value brand almond milk.

The Canadian Food Inspection Agency reported on the infections on July 9.

On July 8 the agency posted a recall notice for the implicated products.

As of July 8, 2024, there were nine confirmed cases of listeriosis reported in Ontario as part of an ongoing investigation that is linked to the recalled products. There have been five hospitalizations associated with this outbreak investigation.

I strongly advise the public, especially those at high risk for listeriosis, such as the elderly, pregnant women and those with weak immune systems, to make sure they do not consume these recalled products, said Kieran Moore, Chief Medical Officer of Health.

The Ministry of Health is working closely with Local Public Health Agencies, Public Health Ontario, the Canadian Food Inspection Agency, Health Canada and the Public Health Agency of Canada regarding the recall of these products.

Anyone who thinks they got sick from consuming one of the recalled products, most of which have best-before dates up to and including Oct. 4, should seek medical advice from their health-care provider.

About Listeria infections
Food contaminated with Listeria monocytogenes may not look or smell spoiled but can still cause serious and sometimes life-threatening infections. Anyone who has consumed any of the recalled products and developed symptoms of Listeria infection should seek medical treatment and tell their doctors about the possible Listeria exposure.

Also, anyone who has eaten any of the recalled products should monitor themselves for symptoms during the coming weeks because it can take up to 70 days after exposure to Listeria for symptoms of listeriosis to develop. 

Symptoms of Listeria infection can include vomiting, nausea, persistent fever, muscle aches, severe headache, and neck stiffness. Specific laboratory tests are required to diagnose Listeria infections, which can mimic other illnesses. 

Pregnant women, the elderly, young children, and people such as cancer patients who have weakened immune systems are particularly at risk of serious illnesses, life-threatening infections, other complications and death. Although infected pregnant women may experience only mild, flu-like symptoms, their infections can lead to premature delivery, infection of the newborn, or even stillbirth.
