The Middlesex-London Health Unit officials in southwestern Ontario say laboratory tests have linked three cases of E. coli O157:H7 to recalled Compliments brand Super 8 Beef Burgers.

However, a spokesman for Ontario’s health ministry said Thursday there have been six confirmed cases of illness in that province associated with the beef in question. Of the six people, four were hospitalized; of the four, one is still in hospital. All are recovering, the ministry said.  The onsets of the six cases of illness in Ontario were between Aug. 16 and Sept. 15.

The recall of the burgers began on Wednesday and covers eight-ounce burgers that were sold frozen in packages of six (with a UPC code of 0 55742 37055 3).  The burgers were distributed in Newfoundland and Labrador, Prince Edward Island, Nova Scotia, New Brunswick and Ontario, and sold through Foodland, Sobeys, FreshCo and Price Chopper stores.
