The chemical, melamine, is believed to have contaminated rice protein concentrate used to make a variety of Natural Balance Pet Foods products for both dogs and cats, the Food and Drug Administration said Wednesday.
Previously, the chemical was found to contaminate another ingredient, wheat gluten, used by at least six other pet food and treat manufacturers (see related stories).
Natural Balance said it was recalling all its Venison and Brown Rice canned and bagged dog foods, its Venison and Brown Rice dog treats, and its Venison and Green Pea dry cat food.
The Pacoima, Calif., company said recent laboratory tests showed the products contain melamine. It believes the source of the contaminant was rice protein concentrate, which the company recently added to the dry venison formulas.
