Many people who became sick reported handling dog food and treats prior to becoming ill, including kibble, and dehydrated and freeze-dried treats. A single common supplier of dog food or treats has not been identified. The investigation is ongoing and this notice will be updated as the investigation evolves.
More recent illnesses may continue to be reported in the outbreak because there is a period between when a person becomes ill and when the illness is reported to public health officials. For this outbreak, the illness reporting period is between 15 and 101 days.
This notice only includes laboratory-confirmed cases. The actual number of sick people in Canada is likely much higher. Many people have mild symptoms and don't go to the doctor, so they aren't tested. Researchers estimate that for each case of Salmonella reported to public health, there are 26 more cases that are not reported.
