MONTGOMERY, Ala. – The Alabama Division of Wildlife and Freshwater Fisheries (WFF) has received confirmation from the Mississippi Department of Wildlife, Fisheries and Parks (MDWFP) that a white-tailed deer from Pontotoc County, Mississippi, tested positive for Chronic Wasting Disease (CWD). According to MDWFP, a 1.5-year-old, free-ranging male white-tailed deer, that appeared to be emaciated and was behaving abnormally, was euthanized on October 8, 2018. The sample was confirmed CWD-positive by the National Veterinary Services Lab in Ames, Iowa, on October 30, 2018. This is the second case of CWD documented in Mississippi.
WFF has tested nearly 8,000 deer since 2002 and has not detected CWD within Alabama. As part of WFF’s CWD Strategic Surveillance and Response Plan, WFF will increase its CWD surveillance sampling efforts beyond typical surveillance rates in those counties within the 50-mile radius of the Pontotoc County CWD-positive white-tailed deer. These counties include Franklin, Lamar, and Marion counties. Standard CWD surveillance methods will be used to collect additional samples for these counties including, but not limited to, voluntary samples from hunter-harvested deer as well as focused efforts on road kills and abnormally behaving deer.
CWD is a neurodegenerative disease found in most deer species, including moose, elk, mule deer and white-tailed deer. It is infectious and always fatal. It is part of a group of diseases known as transmissible spongiform encephalopathies and is similar to mad cow disease in cattle and scrapie in sheep. These diseases cause irreversible damage to brain tissue that leads to neurological symptoms, emaciation and death of the animal.
Deer infected with CWD can spread the disease to other deer even before symptoms develop. It can take one to two years for infected animals to become symptomatic. When symptoms appear, they can include emaciation, lethargy, abnormal behavior, and loss of bodily functions. Other signs include excessive salivation, loss of appetite, progressive weight loss, excessive thirst and urination, and drooping head/ears.
