As the Canadian Food Inspection Agency expanded its warning about beef that may be contaminated with E. coli, the family of a four-year-old Calgary girl says the child became sick after eating tainted beef patties on Labour Day.

CTV Calgary reports that Sarah Demoskoff suffered kidney failure and is on dialysis at Alberta Children’s Hospital, where she has been since Sept. 11.

Sarah’s family told CTV that the girl became very sick shortly after eating prepackaged beef patties.

Health officials in Alberta said Thursday they are investigating five cases of E. coli, including one in Calgary, but they are not linking them to the beef recall.

The Canadian Food Inspection Agency issued a warning Sunday that beef from Edmonton-based XL Foods may be contaminated with E. coli. Since then, the list of stores where the beef may have been sold has expanded several times.

The CFIA said Thursday the voluntary recall now includes beef sold at Sobeys/IGA locations in Alberta, Saskatchewan and Manitoba; Presto and Club Entrepot locations in Quebec; and Co-op locations in Alberta, British Columbia, Manitoba, Ontario, Saskatchewan, the Northwest Territories and Yukon.

The warning could also affect beef sold at various other locations such as small retailers, local meat markets and butcher shops.

Beef products sold between Aug. 24 and Sept. 16 are affected.

Three earlier warnings issued by the food inspection agency since Sept. 16 flagged beef products sold at various branches of Foodland, Metro, Safeway, Giant Tiger, Reddi Food Solutions and other food retailers across the country.

Loblaw Companies Ltd. said some of the recalled meat was sold at its corporate and franchised stores, but not at Loblaws stores themselves.

The company said the stores include locations of Extra Foods, No Frills, Real Canadian Wholesale Club, Shop Easy, SuperValu, Real Canadian Superstore, Westfair and Your Independent Grocer from Manitoba to British Columbia. It also includes these stores in Ontario: No Frills, Kenora; Extra Foods in Marathon, Dryden and Geraldton; Real Canadian Superstore in Thunder Bay; and Real Canadian Wholesale Club in Kenora and Thunder Bay.

Food contaminated with E. coli may not look spoiled, but can cause serious and possibly life-threatening illness. The CFIA said anyone who believes they may have purchased a contaminated product should check with their retailer or discard the product if they are unsure.
