There is no way to prevent cwd, cwd is a natural social contact disease that has been around for many many years. In the last Deer & Deer Hunting issue, theres a very large article on CWD In Wi. The DNR OPENLY admits that their efforts to erradicate the disease has fallen through the cracks. They spent more than 3 Million dollars of tax payers money on a losing battle. They banned baiting in may areas and reduced the baiting limit in the rest of the areas down to 2 gallons. Baiting is a very good management tool and it should be up the to the hunters to decide whether or not they want to bait or not.
