It was from a friend. Backstrap, roast(rump I think) and ground meat. He processed it. I think he's smart, skilled and experienced enough to do it effectively. I'm paranoid about this kind of stuff. Prions, rabies and botulism are the unholy Trinity of my fears.

So rabies you’re in the clear on. There have been no cases of transmission through ingesting tainted meat although it’s not suggested that you eat it. Point is you’re clear.
Botulism can be countered by pressure canning the meat. Your meat is likely safe & you have nothing to worry about, but if you’re still worried pressure can it & you’ll be fine.
Prion proteins are not killable in a pressure canning process. So some of your meat is very likely safe even if your deer had it, but the back straps are in the danger zone. For your hunter friend to be exposing you here he would have had to shoot a deer with the disease & mishandle the meat. If you’re buddy is smart & the deer was shot in your county - with no warnings. You’re likely in the clear. That said as of right now there are no reported transmissions of CWD from deer to humans
