I've not seen or found any dead deer on my place or any neighboring places,but I know of at least 15 deer found dead in northern Pendleton county (I'm in southern Pendleton) and I've heard of several cows dying from it too,this was confirmed by UK's ag dept.
I think it's natures way of compensating for the drought and lack of food this year.The disease has been around a long time and isn't new so I wouldn't sweat it yet.

Meanwhile alot of livestock will suffer this year if we don't get some hay relief.
