The Canadian Food Inspection Agency (CFIA) says a national recall of frozen beef burgers has expanded to some products sold at Loblaws stores.
The CFIA warns the 4-ounce President's Choice Thick and Juicy Burgers could be contaminated with E. coli.
The burgers may be sold at Dominion, No Frills and Save Easy stores in Newfoundland and Labrador.
The meat, which was produced by Belmont Meats, has a best before date of February 25, 2014.
Loblaws has since removed the products from the shelves.
The company has not received any reports of illness from the burgers.
The recall began last week when Sobeys issued a recall for their Compliments brand Super 8 Beef Burgers.
The CFIA said the burgers may not look or smell spoiled but could cause serious illness.
Symptoms of E. coli contamination include severe abdominal cramping and diarrhea, and in more serious causes, could cause seizures or strokes.
