A recently published report has detailed the largest multi-provincial Salmonella outbreak in Canada in more than two decades, linking 515 confirmed cases to contaminated red onions imported from the United States.
The outbreak, which occurred between June and August 2020, affected residents across seven provinces, with 19 percent of those infected requiring hospitalization. The findings, outlined in a report from the Public Health Agency of Canada (PHAC) and other health agencies, underscore the complexity of foodborne illness investigations and the challenges posed by fresh produce contamination.
A separate report from the U.S. Food and Drug Administration in 2020, found that a sheep farm was likely a contributing factor in the contamination of the onions.
