The regs said 5100 animals tested .4% positive in 2010. It does say that there is no scientific proof of it infecting humans, and WHO states it shouldn't enter the food chain.
I've also read that when butchering you should refrain from allowing spinal fluids from contaminating meat. It apparently isolates itself to the brain and spinal cord.
I haven't had an animal that was positive yet, but it has always been to the butchers and eatin before test results returned. They can't be too concerned; wouldn't there be lots of cross contamination through the wild game processors?
