Canada warns of salmonella outbreak tied to dog food
Public health alert issued nationwide
The Public Health Agency of Canada (PHAC) has confirmed 27 cases of salmonella infection linked to handling dog food and treats. The illnesses span multiple provinces, with 13 cases in Alberta, 12 in British Columbia, one in Ontario and one in the Northwest Territories. Six people have required hospitalization, though no deaths have been reported.
Cases reported across age groups
According to PHAC, those affected became ill between mid-February and mid-August 2025, ranging in age from infants to 87 years old. Women represent about 59 per cent of the cases. Officials say many of the sick individuals reported handling kibble, dehydrated, or freeze-dried dog treats before experiencing symptoms.
No single source identified
Investigators have not yet traced the outbreak to a single supplier or brand. PHAC said its probe remains ongoing and updates will be shared as new information emerges. Infectious disease specialists caution that symptoms can range from mild stomach upset to severe gastrointestinal illness requiring hospital care.
How transmission occurs
Health experts emphasize that even healthy dogs can carry salmonella without showing symptoms. The bacteria can be passed to people through direct contact with a dog, its stool, contaminated food, or surfaces. “Dogs can shed the infection in their stool and humans can contaminate their hands … or even through licking,” said Dr. Isaac Bogoch, an infectious diseases specialist in Toronto.
Reducing the risk at home
To lower the risk of infection, PHAC advises Canadians to:
- Wash hands thoroughly with soap and water after handling dog food, treats, pets, or their waste.
- Sanitize containers, bowls, utensils, and surfaces that come into contact with dog food.
- Store pet food separately from human food and keep it away from children.
- Follow package instructions for proper storage, refrigeration, or freezing of dog food and treats.
Broader risks from pet products
Raw pet foods, whether frozen, dehydrated, or freeze-dried, carry higher risks of bacterial contamination, experts warn. Past outbreaks of E. coli, listeria, and campylobacter have been linked to such products. The B.C. Centre for Disease Control notes that close pet-owner interactions—such as sharing beds or being licked—can also increase the chance of infection, especially for children, seniors, and immunocompromised individuals.
Ongoing investigation
PHAC says Canadians should remain vigilant until the investigation determines the source. While salmonella infections are often self-limiting, public health officials stress the importance of preventive measures to protect both families and their pets.
