I hunt deer in a CWD unit and have never bothered getting a CWD test. The CDC has a lot of information on the disease. http://wwwnc.cdc.gov/eid/article/10/6/03-1082_article I have read through the material and decided, for myself, that the risk of transmission to humans is low to non-existent. Everyone needs to make their own decision on the matter but I feel safe with it. I do avoid the brain and spine as much as possible.

By the way, elk can carry CWD as well as deer.
