A brand of dog treat is being recalled because it may contain salmonella bacteria, the Canadian Food Inspection Agency warned Thursday.

The Roll Over Pork Tenders Premium Dog Treats pose of risk of salmonella infection to people handling the treats or in contact with pets who have used the treats, the warning said. Any one who may have handled the treats should wash their hands with warm water and soap.

One illness has been reported in connection with the recalled treat, made by Alberta-based Rollover Premium Pet Food and sold in 50-gram packages across the country. The recall affects products dating back to March 2007 with UPC 060766 88138 1.

Consumers should dispose of the treats immediately, the agency said.

Common symptoms of salmonella infection include nausea, vomiting, abdominal pain and diarrhea, although more serious consequences are possible, especially in children, the elderly and those with weakened immune systems.
