The U.S. Food and Drug Administration issued a final regulation barring certain cattle materials from all animal feed, including pet food. The final rule further protects animals and consumers against bovine spongiform encephalopathy.
The new measure builds on FDA’s 1997 feed regulation, which prohibited the use of certain mammalian proteins in ruminant feed. The materials that can no longer be used in animal feed are the tissues that have the highest risk for carrying the agent thought to cause BSE. These high-risk cattle materials are the brains and spinal cords from cattle 30 months of age and older. The entire carcass of cattle not inspected and passed for human consumption is also prohibited, unless the cattle are less than 30 months of age, or the brains and spinal cords have been removed. The risk of BSE in cattle less than 30 months of age is considered to be exceedingly low.
The removal of high-risk materials from all animal feed will further protect against inadvertent transmission of the agent thought to cause BSE, which could occur through cross-contamination of ruminant feed (intended for animals with four-chambered stomachs, such as cattle) with non-ruminant feed or feed ingredients during manufacture and transport, or through misfeeding of non-ruminant feed to ruminants on the farm. The added measure of excluding high-risk materials from all animal feeds prevents any accidental feeding of such ingredients to cattle.
The regulation finalizes a proposed rule that the FDA issued for public comment in October 2005. The final rule is effective 12 months from the issue date (April 24, 2008) to allow the livestock, meat, rendering, and feed industries time to adapt their practices to comply with the new regulation.
