More detail please.
We leave their heads when we take them in to be tagged. The DNR will test them for free. They just need a sample of the brain or spinal cord fluid. The deer hangs in the shed for a few days, while we're awaiting the results. And if it has a really nice rack, we hang around and WAIT for the results, LOL!
The deer we harvest are on our own land. The nearest CWD deer are a few counties over, but we just want to stay ahead of this.
I don't consider testing our deer for CWD to be any more of a hassle than washing purchased fruits and vegetables well after they come home from the grocery store. I don't buy much 3/4 of the year because I do have a 1/4 acre organic garden and an orchard. It just makes sense to me all the way around, to be safe about your food, CWD or not. :)
(I'm not a freak about it; I have just gotten into the habit about being smart about what I feed myself and my family. The exceptions to that rule would be Cheetos and inexpensive beer, LOL!)
