If you have any red onions in your cupboard grown in the United States you should not eat them, but throw them out immediately.

That’s according to the Public Health Agency of Canada who are in an ongoing investigation into a salmonella outbreak that has made 55 Albertans sick.

The illness’ have been linked to red onions imported from the US in Alberta, British Columbia, Saskatchewan, Manitoba and Ontario.

Individuals should check food packaging that might contain raw red onions and ensure the place of origin; if the food was packaged in the US it should be thrown out.

Red onions grown in Canada are still fine to use.

Salmonella symptoms include fever, chills, diarrhea, abdominal cramps, headache, nausea and vomiting.
