Update: Pet food recall widened

The pet food recall expanded further Tuesday to include products made at a Canadian factory recently found to have used an ingredient tainted by an industrial chemical.

Menu Foods previously had recalled only cat and dog food made at its plants in New Jersey and Kansas, saying they were its only facilities to have taken delivery of imported wheat gluten later found contaminated with melamine.

However, Menu Foods discovered Monday that some of the tainted wheat gluten had made it to Canada. It was prompted to account for the ingredient by the U.S. Food and Drug Administration, which told the company that tests had detected the chemical in pet foods made at its Streetsville, Ontario, plant.

Among the products covered by the expanded recall is Royal Canin Canada's Medi-Cal Feline Dissolution Formula canned diet, made by Menu Foods and sold only through veterinarians. A single production lot contained the contaminated wheat gluten, the company said.

Natural Balance Pet Foods recalled two kinds of pet food after receiving reports of animals vomiting and experiencing kidney problems, the Food and Drug Administration said Monday.

The recall includes all date codes of Venison & Brown Rice Dry Dog Food and Venison & Green Pea Dry Cat Food.

The company does not know the cause of the problem, but said it is focused on one particular lot.

Natural Balance Pet Foods is working with the FDA to investigate the matter and is urging consumers to not feed either pet food product to their animals.
