Gun Tramp, that's a great question. In Minnesota, during the normal firearms season, the DNR is providing special dumpsters stationed around the CWD hunting zones for all carcasses or disposal of infected deer. Now...what they do after that I don't know. Just to give you an idea of how resistant these prions are, here's more info I've found:
In general, prions are quite resistant to proteases, heat, ionizing radiation, and formaldehyde treatments, although their infectivity can be reduced by such treatments. Effective prion decontamination relies upon protein hydrolysis or reduction or destruction of protein tertiary structure.
Prions cannot be destroyed by boiling, alcohol, acid, standard autoclaving methods or radiation, he said. ... Right now it is not clear what it takes to destroy prions, Moench said, but tests have shown some types may survive cremation temperatures of 2,000 degrees.
On one infected elk farm about 20 miles from me, after they destroyed the entire herd...at taxpayer expense...they proceeded to remove 6" to 10" of soil off the entire farm that was hauled away to some facility for decontamination. BTW...that was all at taxpayer expense as well. I don't even want to imagine what that cost.
Get the picture why these deer farms are getting under my skin??? All this so some hunter can put some urine on the ground to attract a deer or some guy in China can consume some dried antler velvet in lieu of a Viagra pill??? Considering the effects on our wild animal populations, the long-terms effects this is and will continue to have on our hunting, and all the cost, I just don't know how deer farms can be justified anymore. The risk/reward balance is now way out of proportion.
