Put down that BambiBurger. Venison may be suffering from a disease strikingly similar to Mad Cow disease. Now would be a good time to cancel that Deer or Elk hunting trip, too -- especially if you're hunting Deer or Elk that may have Ft. Collins, CO, Wisconson, or South Dakota.
(Moose and Squirrel hunting is still OK, at least this week.)
Remember, Mad Cow has never surfaced in the US, so that undercooked 100% pure beef burger should still be OK. (Note: most cows are slaughtered in the US before symptoms of Mad Cow Disease emerge.)
