Salmonellosis Associated with Cheese Consumption -- Canada

Several hundred cases of salmonellosis caused by Salmonella typhimurium phage type 10 have been reported from Prince Edward Island, Newfoundland, New Brunswick, and Ontario, Canada, in recent months. These cases have been traced to eating cheese produced by Amalgamated Dairies, Ltd. (ADL) of Summerside, Prince Edward Island. Several different types of cheese, including colby, cheddar, mozzarella, and farmer's cheese, may have been contaminated. The cheeses, which were sold under many different labels, have been recalled in Canada. The brands packaged by ADL that have been recalled are Tyne Valley, Clover Cream, and ADL. In addition, mild and medium cheddar cheese bearing the registration number 1413 (Canada Packers Inc., Toronto, Canada) of the brand names Maple Leaf, Calbeck, Co-op., I.G.A., N & D, and Western Family have been recalled. Mild cheddar cheese bearing the registration number 1557 (Winchester Cheese, Inc., Winchester, Canada) of the brand names J. M. Schneider, Loblaws (including No Name and No Frills), Dutch Boy, Super Value, Quick Save, Dairy Pride, Zehrs, and Sunspun have also been recalled.

To date, CDC is not aware of any distribution of the cheeses in the United States, but it is possible that U.S. citizens have been infected by eating cheese in Canada or by bringing cheese back to the United States. Consumers are advised to discard the product or to return it to the place of purchase. Reported by Health Protection Br, Health and Welfare, Canada; Emergency and Epidemiology Operations Br, U.S. Food and Drug Administration; Enteric Diseases Br, Div of Bacterial Diseases, Center for Infectious Diseases, CDC.
