HARRISBURG, Pa.,  March 1, 2013 — The Pennsylvania Game Commission today confirmed three hunter-killed deer taken in the 2012 general firearms deer season have tested positive for Chronic Wasting Disease (CWD). Two were from  Blair County; the other was from  Bedford County. 

“These are the first positive cases of CWD in free-ranging deer in  Pennsylvania,” confirmed Pennsylvania Game Commission Executive Director  Carl G. Roe. “The disease was first documented in early October, 2012, by the state Department of Agriculture in a captive deer on an  Adams County  deer farm.”

The three hunter-killed deer tissue samples were collected by Game Commission personnel during annual deer aging field checks during the general firearms season for deer. The samples were tested and identified as suspect positive by the Department of Agriculture as part of an ongoing annual statewide CWD surveillance program. The tissue samples were confirmed to be positive for CWD by the National Veterinary Services Laboratories in  Ames, Iowa, as part of an established verification process. 

“The three CWD-positives were part of 2,945 deer sampled for the disease statewide,” explained Roe. “To date, we have received test results from 1,500 samples, including these three positive samples.  Results from the remaining samples should be available in the next few weeks.”

An additional 2,089 deer were sampled and tested from within the designated Disease Management Area in  Adams  and  York  counties; CWD was not detected in any of those deer samples. Since 1998, the Game Commission has gathered and submitted more than 43,000 samples from wild deer and elk for CWD testing. The three CWD-positives announced today are the first to be confirmed in 15 years of testing.

“Pennsylvania  has an active Interagency CWD Task Force and a dynamic CWD surveillance program,” Roe noted, “and we will continue to be vigilant and initiate steps included in the Commonwealth’s CWD Response Plan. We will continue to work diligently with the Department of Agriculture and other members of the task force to better manage the threat of this disease to the state’s captive and wild deer populations.”

The Game Commission is working to identify and engage the hunters who harvested these CWD-positive deer to confirm where the whitetails were killed. A meeting of the Interagency CWD Task Force is being convened this afternoon to discuss the new CWD-positive deer and possible additional actions to determine the prevalence and distribution of the disease within  Pennsylvania, as well as to contain its spread. 

The latest information and updates to existing CWD information can be accessed on the Game Commission’s website (www.pgc.state.pa.us). Public meetings will be held in the  Blair-Bedford County  area in coming weeks to share what we know about these CWD-positive deer and CWD in  Pennsylvania, and to answer questions the public might have about this disease. How these latest developments may influence hunting regulations and other deer policies are at this time still contingent upon the results of ongoing testing of samples from hunter-killed deer, additional surveillance and fieldwork, and Game Commission and task force deliberations.

CWD is a degenerative brain disease that affects elk, mule deer and white-tailed deer. It is transmitted by direct animal-to-animal contact through saliva, feces and urine. CWD is fatal in deer and elk, but there is no evidence that CWD can be transmitted to humans, according to the Centers for Disease Control and Prevention and The World Health Organization.

Signs of the disease include weight loss, excessive salivation, increased drinking and urination, and abnormal behavior such as stumbling, trembling and depression. Infected deer and elk also may allow unusually close approach by humans or natural predators. There is no known treatment or vaccine.

CWD was first discovered in  Colorado  captive mule deer in 1967, and has since been detected in 22 states and Canadian provinces, including  Pennsylvania’s neighboring states of  New York,  West Virginia  and  Maryland.
