U.S. makers of pet food and all other animal feed will be prevented from using certain materials from cattle at the greatest risk for spreading mad cow disease under a rule that regulators finalized on Wednesday.
The U.S. Food and Drug Administration, which oversees animal feed, said excluding high-risk materials from cattle 30 months of age or older from all animal feed will prevent any accidental cross-contamination between ruminant feed (intended for animals such as cattle) and non-ruminant feed or feed ingredients.
