The Food and Drug Administration (FDA) continues to implement more stringent
regulations to thwart the potential spread of bovine spongiform encephalopathy
(BSE, or "mad cow" disease) in the United States after the discovery of an
infected Holstein in December. The agency has now imposed several bans that
will affect human food, including dietary supplements, and cosmetics.
Material from "downer" cattle (animals too sick or injured to stand)
or cattle that die before slaughter will be banned, along with other bovine-derived
material, including risk materials from any cows 30 months or older (such
as brain, skull, eyes, and spinal cord), as well as a portion of the small
intestine and tonsils from all cattle.
