Second Chronic Wasting Disease Case Found in Maryland Deer
The Maryland Department of Natural Resources received laboratory confirmation on February 28 that a second white-tailed deer harvested in Maryland tested positive for chronic wasting disease (CWD). The adult female deer was harvested in Allegany County in December 2013 during firearm season.
The first confirmed case of CWD in Maryland was reported in February 2011, also from Allegany County. Maryland is one of over 20 states and Canadian provinces with CWD documented in deer, elk or moose.
“Chronic wasting disease has become firmly established in the region since it was initially found in West Virginia in 2005,” said Karina Stonesifer, acting director of DNR Wildlife and Heritage Service. “The department has followed this outbreak closely and has been prepared to find additional infected deer in Maryland. We have sampled intensively for this disease since 2002 and see this as an unfortunate but inevitable outcome. We will continue to manage CWD with the best available science to minimize the impact on our deer population and the people who enjoy these great animals.”
Concerns over CWD should not stop anyone from deer hunting and enjoying venison. There is no evidence that the disease can be transmitted to humans, livestock or other animals. As always, hunters are advised to never consume the meat of sick animals. Hunters should also avoid the brain, spinal column or lymph nodes of deer — all of which are normally removed during the butchering process.
This is the second positive sample out of nearly 7,500 deer tested in Maryland since 1999. Since 2010, sampling efforts have been focused on Allegany and western Washington counties due to the presence of CWD in nearby West Virginia, Virginia, and recently, Pennsylvania.
CWD is a fatal disease that attacks the brain and spinal cord of deer and elk, specifically white-tailed deer, moose, mule deer and Rocky Mountain elk. While the exact cause is not known, it is believed to be a prion disease. A prion is an altered protein that causes other normal proteins to change and cause sponge-like holes in the brain. The disease appears to be passed between animals via saliva, feces or urine. For more information on CWD in Maryland, click here.
