A massive voluntary recall of beef that began in Western Canada has now spread to the Maritimes.

Beef and beef products sold at several large chain stores over the last three weeks may contain E. coli.

“I’ll definitely check my freezer,” says Halifax resident Margaret Taylor. “I'd rather be safe than suffer the consequences.”

The Canadian Food Inspection Agency has expanded a voluntary recall for various beef products possibly contaminated with E. coli. The warning came from XL Foods, a distributor based in Edmonton.

The recall is for ground beef, meatballs, hamburger patties, meatloaf and stuffed green peppers at various grocery stores such as Walmart, Costco and Sobeys. Distribution areas extend to New Brunswick, Nova Scotia and Prince Edward Island.

The beef in question was packaged between August 27 and September 16 and could have a best before or freeze by date ranging from August 29 to September 23.

“As an individual, if you consumed ground beef that had E. coli and you cooked it properly, you'd have nothing to worry about,” says Mike Horwich of Nova Scotia Agriculture and Food Protection.

Meat contaminated with E. coli might not look or smell spoiled. Although no one has reported feeling ill, the recall is being treated very seriously because of how harmful the bacteria can be.

Symptoms include severe abdominal pain and diarrhea. It can cause seizures, strokes and kidney damage and even death in extreme cases.

“The symptoms usually take between one day to 14 days,” says Horwich. “They start mild and can progress. So, if you feel that way please consult your medical practitioner.”

The CFIA will continue its investigation and work with recall firms and distributors to verify all affected products. Consumers are being encouraged to contact grocery stores directly.
