Public Health Notice

The Public Health Agency of Canada (PHAC) is collaborating with federal and provincial public health partners, the United States Centers for Disease Control and Prevention (U.S. CDC), and the U.S. Food and Drug Administration to investigate an outbreak of Salmonella infections occurring in seven provinces.

In Canada, based on the investigation findings to date, exposure to red onions imported from the USA has been identified as a likely source of the outbreak. Many of the ill individuals under investigation reported having eaten red onions before getting sick.

Since August 7, there have been 100 additional illnesses reported in the ongoing Canadian investigation. There are now 339 confirmed cases in Canada.

There is no evidence to suggest that onions grown in Canada are associated with this outbreak. Onions imported from the United States are under investigation.

Do not eat, use, sell or serve any red, white, yellow, and sweet yellow onions from Thomson International Inc. of Bakersfield, California, USA, or any products made with these onions. This advice applies to all individuals across Canada, as well as retailers, distributors, manufacturers and food service establishments such as hotels, restaurants, cafeterias, hospitals and nursing homes.

If you are not sure where a red, yellow, white, or sweet yellow onion was grown, do not eat it. This notice contains more advice on how to avoid getting sick.
