If you are worried that you have taken a chronically wasted whitetail you can always have it tested. As for cleaning your knives and other butchering tools you can use a strong bleach. Still no chronic wasting disease here in chronically wasted new york..
As for the Prion business - you can get those in Squirrel brains. Some fellow down south cooked up a meal of squirrel brains and died from something related to the Prions in the squirrel brains, so they think.
So far, no humans have become chronically wasted from coming into contact with Whitetail or Elk so the research says if you look it up in the Greybeard search thingy up at the top of the page.
So, you can stew all you want or you can make stew all you want. I think if you are going to suffer from being in contact with a critter that is suffering from chronic wasting disease you probably will if you ever do - come into contact with them that is, but you may not catch anything contagious. These research 'findings' seem to suggest that we will all suffer from this worse than the last plague but I don't know of any who have died of this disease. Of course, someone with multiple medical issues might possibly pick something up but will it kill he or she any faster than what they already suffer from?
When you think of all the other deadly dangerous gonna killya right then and there diseases humans are supposed to have suffered from over the last two centuries it is a miracle we are even still standing as a distinct species. I'm no fan of a lot of 'focused' research but yet there is no proof that people have died from this. Just sayin'
