Unless it is a prion, proper cooking will kill it. Mad Cow, and it's "cousin" Creutzfeldt-Jakob disease are prions. I also suspect that the other neurological wasting diseases common to hoofed game animals are. Though... that is speculation on my part.
You're correct about CWD, Chronic Wasting Disease in deer population. It is a prion disease. DH tries to harvest young animals (less chance of them having it) and we get ours tested for CWD. Have not gotten a positive, and hope we never do!
