The Canadian Food Inspection Agency warned the public on Wednesday not to eat the Atkins Advantage Peanut Butter Granola Bar because it may be contaminated with salmonella.

The granola bar, manufactured in Canada, comes in 48-gram packages and carries best-before dates of June 6, 2009, and July 19, 2009.

The agency said the granola bar contains peanut products that have been recalled in the U.S. and Canada by the Peanut Corporation of America as a result of a salmonella outbreak that has made 600 people sick in the U.S. The outbreak may be linked to eight deaths.

Canadians were also warned not to consume chocolate-covered peanuts, including sugar-free ones, sold in unmarked, clear plastic, cone-shaped containers with gold foil tops, by Golden Chocolate in Lakeshore, Ont.

The chocolate-covered peanuts, manufactured in the U.S., come in 220-gram and 440-gram packages.

The warning also applies to Sunbird Snacks yogurt trail mix, health mix and chocolate peanut butter blast, all manufactured in the U.S. but which may have been available in Canada.

"This is an ongoing food safety investigation," the agency said in a news release Wednesday.

The agency said it is working with the U.S. Food and Drug Administration to identify and remove all affected products imported into Canada from the U.S.

CFIA is also working with Canadian manufacturers to recall foods containing affected U.S. peanuts.

The salmonella outbreak has led to the recall of more than 1,800 products in the U.S. and more than 200 products in Canada.

Peanut Corp. is currently being investigated by the Federal Bureau of Investigation in the U.S. Its corporate headquarters in Lynchburg, Va., were raided by the FBI on the weekend, and two of its plants, one in Georgia and the other in Texas, have been closed while the investigation continues.

It makes only about one per cent of U.S. peanut products, but its ingredients are used by dozens of other food companies.
