types of live animals from countries where mad cow disease is known to

addition, prohibiting high-risk animals from entering the food supply and the
removal of central nervous system tissue from the food supply helps assure that
BSE is not a risk to consumers.
In addition, the FDA stops the importation of cosmetic and dietary
