I'm sure the DNR folks are looking at all the info and research available to curb the spread, but it is a tenacious problem in the deer herds, fortunately, a fairly low infection rate in most places. Our testing program is a "no news is Good news", CPW(DNR) only responses to positive cases, but you get a free replacement tag. They also recommend not eating the meat or feeding it to pets. It sort of seems to be making a loop, I understand the first cases were in the Great Lakes region and it came west and north. Good luck!
