It's known as Chronic Wasting Disease, and it's been around for more than a decade. In recent years, however, it has spread across Canadian prairies and animals at an alarming rate. In some places, up to 80 percent of deer populations tested may be infected. The illness makes animals like deer and elk waste away from the inside, looking like something from a horror movie (hence 'Zombie Deer').So far the disease has not moved to humans, or other unrelated animals. But it is certainly possible. Meanwhile, funding for testing, research and potential vaccines is tough to come by. So why aren't we taking this seriously? Should we? How urgent is this crisis?GUEST: Debbie McKenzie, University of Alberta professor and prion disease researcher
