"The Wisconsin Medical Society on Thursday warned hunters that no test can tell them whether the venison from their deer is safe to eat," reports Ron Seely. Nevertheless, state officials are urging hunters to go all-out in harvesting (and consuming) deer in the hope that a special hunt will kill enough to halt the spread of chronic wasting disease (CWD). Like mad cow disease, CWD disease is a fatal brain illness caused by an infectious, malformed protein called a prion. To egg on hunters, the state Department of Natural Resouces is paying for an advertisement on area radio stations that features a jingle [3] with lyrics including "Bagem tagem dragem, freezem testem fryem. I ain't afraid of no twisted little prion."
