Wisconsin officials have confirmed that a white-tailed deer harvested from a Portage County hunt ranch has tested positive for chronic wasting disease. The 3-year-old buck was purchased from a Portage County breeding farm, according to a Nov. 15 news release from the Wisconsin Department of Agriculture, Trade and Consumer Protection..

Both ranch and farm have been quarantined. No animals may move in or out of the farm and the movement of carcasses has been further restricted.

The 11-acre breeding farm has 42 whitetail deer, is double-fenced and is enrolled in the CWD herd status program. The hunt ranch as 156 deer and elk and will have additional testing requirements to better monitor and analyze the spread of the disease.

CWD is a fatal, neurological disease of deer, elk and moose caused by an infectious protein called a prion that affects the animals brain. Testing for the disease can only be performed after the deer's death.
