Extensively Drug-Resistant Salmonella Outbreak Linked to Raw Pet Food and Cattle Contact

The Public Health Agency of Canada (PHAC) has linked an ongoing outbreak of drug-resistant salmonella to raw pet food and contact with cattle. Forty confirmed cases, including thirteen hospitalizations, have been reported across six provinces from July 2020 to September 2023. Children under five account for forty-three percent of cases. While no human deaths are reported, some infected dogs and cattle have died. Investigations have not identified a common pet food supplier, but exposure to raw pet food and contact with cattle, especially calves, are cited as likely sources. The PHAC advises against feeding pets raw food due to the risk of bacterial transmission and underscores hygiene precautions.
