WASHINGTON - An industrial chemical that led to a nationwide recall of more than 100 brands of cat and dog foods has been found to contaminate a second pet food ingredient, expanding the recall further.
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.
