The Canadian Food Inspection Agency says green onions sold at five Highland Farms supermarkets in the GTA have tested positive for salmonella bacteria.
The outbreak is suspected of making 25 young people sick in the area where they were sold.
The onions were unmarked and unwrapped and don't contain a lot code sticker, UPC or product name.
The onions were sold at the Highland Farms supermarkets at 4750 Dufferin St., 3300 Rutherford Rd. in Vaughan, 850 Ellesmere Rd. and 148 Bennett Rd. in Scarborough and 50 Matheson Blvd. in Mississauga.
Anyone who purchased onions at these stores is being warned to throw them out.
The Ontario Ministry of Health meanwhile, is continuing to investigate the outbreak to see if other sources or foods might have been involved.
Food contaminated with Salmonella may not look or smell spoiled. Consumption of food contaminated with these bacteria may cause serious illness in young children, the elderly and people with weakened immune systems. In otherwise healthy people, salmonellosis may cause short-term symptoms such as high fever, severe headache, vomiting, nausea, abdominal pain and diarrhea. Long-term complications may include severe arthritis.
