I spend a lot of time studying CWD and have also not heard of a single transmission of CWD by bring an infected animal head/carcass into another state.
Just something to think about--back when England had that BSE (mad cow) prion outbreak in the cows, only a few hundred people got it. When you look at how many cows had it, and estimate how many were slaughtered and put into the food supply before they knew what was happening, in all probability all the beef-eaters in England got some of that meat. Most of them never showed any symptoms. In all liklihood, a few of us will eventually die from eating CWD carrying deer, but most of us are probably immune.
