Pennsylvania finds more deer with CWD

Harrisburg — Pennsylvania’s statewide deer seasons have come to a close, and all final chronic wasting disease test results will soon return from deer harvested by hunters in the 2017-18 seasons.

The Pennsylvania Game Commission collects samples from deer harvested across the state and tests them for chronic wasting disease, as part of the agency’s ongoing CWD surveillance.

Within the state’s disease management areas – where the disease has been detected in captive and free-ranging deer – intensified sampling occurs.

This past hunting season, the commission offered free CWD testing for hunters harvesting deer within disease management areas. Free testing offered hunters a way to have their deer tested prior to consuming it, and it provided the commission with additional samples to better pinpoint areas where the disease exists.

Successful hunters within disease areas dropped off heads from more than 1,500 deer in the boxes. About 1,000 of these samples already have been tested for CWD, with the results reported to hunters.

Additionally, Game Commission staff collected more than 3,000 other samples within disease management areas to test for CWD. In total, nearly 8,000 samples were collected statewide.

Slightly more than 5,700 whitetails were tested for CWD in 2016; 25 tested positive, all were in or near Disease Management Area 2, the only area of the state where CWD has been detected in the wild.

As of this report, 51 deer from the 2017-18 hunting seasons have tested positive for CWD. All have been within the disease areas. Forty-eight were within area 2, in southcentral Pennsylvania; and three were within area 3 in northcentral Pennsylvania.

But the majority of samples collected still are being analyzed.

Wayne Laroche, the Game Commission’s special assistant for CWD response, said the agency will continue to assess the incoming test results to evaluate the best response to confront CWD where it exists.

Disease management area boundaries regularly have been adjusted in relation to newly detected CWD-positive animals. And last year, the commission teamed with the U.S. Fish and Wildlife Service on a CWD surveillance effort where 30 deer were removed by sharpshooters and one CWD-positive deer was detected.

“By developing a control program where we go into these hotspots and remove the animals with a greater likelihood of carrying the disease, we might stand our best chance of controlling CWD on a larger scale, while minimizing the impact on the larger deer population or diminishing deer hunting opportunities,” Laroche said.

CWD is not a new disease, and other states have decades of experience dealing with CWD in the wild. It first was detected in Pennsylvania in 2012 at a captive deer facility, and it was detected in free-ranging deer soon after. To date in Pennsylvania, CWD has been detected in 98 free-ranging deer.

CWD is spread from deer to deer through direct and indirect contact. The disease attacks the brains of infected deer, elk and moose, and will eventually result in the death of the infected animal. There is no live test for CWD and no known cure.

There also is no evidence CWD can be transmitted to humans, however, it is recommended the meat of infected deer – or deer thought to be sick – not be consumed.
