Question 6.14: Would the laws of Kashrut prevent Mad Cow Disease?

                                  Answer:
   
   Mad Cow disease is believed to result from the consumption of cattle
   that have been fed food that unwittingly included tissue of diseased
   beef. The laws of Kashrut do not forbid feeding cattle food containing
   beef products (although Judaism would prohibit knowingly feeding the
   cattle diseased food).
