A new study shows that hunter-killed deer in Pennsylvania are clear of disease. The New Bolton Center, a veterinary diagnostic laboratory at the University of Pennsylvania, conducted tests on hunter-killed deer and elk in Pennsylvania and found no trace of c-w-d. C-w-d is known as chronic wasting disease. The study comes in light of c-w-d being found in New York and West Virginia in 2005. Each year, the number of samples tested for the disease increases, giving doctors a better chance of finding the disease in the deer and elk. The testing done on the animals cost seventy-five-thousand, and was paid for by a grant from the U.S. Department of Agriculture.
