Maryland Free of CWD Maryland Department of Natural Resources says no signs of chronic wasting disease were found in wild deer harvested during the 2004-2005 muzzleloader and firearms deer-hunting season. A total of 872 deer were tested out of nearly 75,000 deer harvested. The agency determined that if 1 percent of deer had CWD, there’s a 98 percent chance that it would have been detected in the sample.
