it's probably more likely that you'd get infected with some prion by breathing the dust from the bone meal you fertilize your roses with than eating the flesh of wild deer or sensibly raised cow, pig, or chicken. reality is that even if you are infected, you probably won't know it for 20 years. I'm not going to stop killing and eating deer or squirrels. I'm not going to stop buying quality beef, pork or chicken, but I am going to go out of my way to find clean, reputable, local sources for the meat I do buy from now on. I won't being eating any brain matter. not that I ever would, but I read a rather disturbing excerpt in a book about a very localized outbreak of CJD in Western Kentucky where eating squirrel brains was a common tradition. it was not a coincidence. the way I understand it, there is greater risk in consuming things that contain meat and bone by-products. the kind of stuff born in rendering plants and found in processed foods, fast foods, etc, and gelatin, of all things, is one of those things.
