The 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. And that has led to another recall.
The Food and Drug Administration says 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 chemical was earlier found to taint another ingredient, wheat gluten, used by at least six other pet food and treat manufacturers.
Natural Balance says it is 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 California-based company said recent lab tests showed the products contained melamine.
