A pet food company is recalling batches of nine brands of dry pet food sold across Canada and the U.S. because of potential salmonella contamination.

U.S.-based Diamond Pet Foods said in a statement released Saturday it has withdrawn several different brands of dry pet food.

The company says there have been no reported cases of infections, but has voluntarily issued the recall as a precaution. The bags affected were manufactured between Dec. 9, 2011, and April 7, 2012.

They include the following brands:

• Chicken Soup for the Pet Lover's Soul
• Country Value
• Diamond
• Diamond Naturals
• Premium Edge
• Professional
• 4Health
• Taste of the Wild
• Kirkland Signature

The recalled bags have the number two or three in the 9th or 10th digit on the item code followed by an "X." The best before dates are between Dec. 9, 2012, and April 13, 2013.

Jeff Kelly, who runs three Global Food pet stores in New Brunswick, said the threat isn't just for animals.

Salmonella can cause nausea, vomiting, diarrhea, stomach cramps and fever in both pets and humans.

"Handling the foods, not cleaning your hands after handling to food or a dog could transmit it to a person," he said.

Diamond ships its product to New Brunswick, but it is then distributed throughout the region, he said.

"It's not just in our stores. It's virtually in any store, including grocery stores."

Kelly said pet owners can return the dry food to retailers for a refund.
