The Canadian Food Inspection Agency is warning the public not to eat a number of products containing peanut butter over concerns they may be contaminated with salmonella.

The products, sold under the brands Harry & David, Wolferman's, Fairytale and Justin's, range from peanut butter spreads, cookies, brownies and gift baskets. They may have been sold across Canada through internet sales from the United States.

The CFIA warning says there have been no reported illnesses associated with consumption of the items, which have been recalled in the U.S.

Food contaminated with salmonella may not smell or look spoiled, the CIFA said in a release, but can cause serious and sometimes deadly infections in young children, the elderly and those with weakened immune systems.

For healthy people, eating salmonella contaminated foods can cause short-term symptoms including high fever, severe headache, vomiting, nausea, abdominal pain and diarrhea. It can also cause long-term complications including severe arthritis.

A complete list of the products can be found on the CFIA website.
