What is CWD?
Chronic wasting disease is a fatal neurological disease that affects members of the deer/elk family (cervids). It was first described in 1967 in Colorado and since has spread to 26 states, Canada, South Korea, Finland and Norway. CWD is similar to scrapie in sheep/goats and “mad cow disease” in cattle. These diseases are caused by misshapen proteins called prions, which accumulate in the tissues of affected animals, especially the brain, spinal cord, and lymph nodes. CWD is a slowly progressing disease. Infected animals will not show signs of disease for a long period of time, but late in the disease process, they will be thin and may demonstrate weakness, abnormal behavior, excessive thirst, or drooling. Animals generally die soon after the onset of these signs.
Where in Arkansas Has CWD Been Found?
In February 2016, an elk harvested in the fall of 2015 near Pruitt in Newton County tested positive for CWD. This was the first documented case of the disease in the State of Arkansas. Also in February 2016, a white-tailed deer was found sick near Ponca in Newton County and tested positive CWD. An initial sampling effort in the vicinity of these cases found a total CWD prevalence of 23 percent in white-tailed deer from northern Newton County. Additional CWD positives have been found in Benton, Boone, Carroll, Independence, Johnson, Logan, Madison, Marion, Pope, Scott, Searcy, Sebastian and Washington counties. Surveillance for this disease continues statewide. AGFC continues their surveillance activities and encourages Arkansans to report all sick deer and elk, 1-800-482-9262.
Can CWD Spread to Humans or Livestock?
Currently, there is no scientific evidence of CWD transmission to humans, pets or livestock under natural conditions. However, feeding domestic animals any meat from sick or diseased wildlife is not recommended.
The Centers for Disease Control and Prevention strongly recommends having your deer or elk tested when hunting in areas where CWD is known to be present before eating the meat.
Visit the Centers for Disease Control and Prevention for more information about CWD from the Centers for Disease Control.
What Can Be Done to Manage CWD?
Research suggests the CWD prion can be passed from infected cervids to healthy cervids through contact with feces, urine, or saliva as well as contact with CWD-infected carcasses or contaminated soil. Practices which unnecessarily congregate cervids or the improper disposal of carcasses both have the potential to increase CWD transmission. Therefore, steps to reduce the spread of CWD include avoiding activities which congregate deer and elk, reducing deer and elk densities, limiting the movement of potentially infected materials (i.e. carcasses) around the state, and limiting the dispersal of infected animals. In order to slow the spread of CWD within Arkansas, the AGFC has enacted regulations to help slow the spread of CWD in Arkansas.
