The human death toll from British mad cow disease is doubling every three years. A version of mad cow disease unique to the U.S. is killing deer across North America; young hunters are dying from it.

With a new chapter of their 1997 book, Rampton and Stauber reveal a terrifying tale of governmental neglect and industry malfeasance.
