Hershey Canada has recalled many chocolate bars and baking products — including Hershey bars, Reese's Peanut Butter Cups and Oh Henry! bars — because they may be tainted with salmonella.

Hershey Canada Inc. and the Canadian Food Inspection Agency (CFIA) released a list on Sunday of 25 products they saycould be contaminated with the bacteria.

Foodcontaminated with salmonella may not look or smell spoiled, but the bacteria can cause symptoms such as high fever, severe headache, vomiting, nausea, abdominal pain and diarrhea.

There have been no reported illnesses associated with the consumption of the candy or chocolate chips on the recall list, the company said.

But the agency is warning people not to eat any of thoseproducts, which are listed on itswebsite.

The company'splant in Smith Falls, Ont., was closed Friday after the salmonella was discovered.

The company, which is based in Mississauga, Ont.,said the products carry dates between Oct. 15 and Nov. 10. It said they do not include candy soldin bags for Halloween or Christmas items.

CFIA said the products were sold across Canada and that Hersheyis voluntarily recalling themfrom the marketplace.
