Biological samples reveal 70 new cases of CWD, no new counties affected

Seventy new cases of chronic wasting disease have been found in Arkansas since deer season opened in September, according to samples collected by Arkansas Game and Fish Commission biologists, taxidermists and veterinarians. Although the number of positive cases is high, no samples from new areas of the state have been found so far. The disease has been found in Boone, Carroll, Madison, Marion, Newton, Pope and Searcy counties since September.

Cory Gray, manager of the AGFC’s Research, Education and Compliance Division, says overall the results have been as good as can be expected.

“We have taken more than 2,400 samples so far this season, and we have several batches of samples still at the laboratory,” Gray said. “But most of the positive cases are reinforcing where we believe the disease is most prevalent. Once we have completed this year’s sampling, we hopefully will have a clearer picture of disease distribution.”

Gray says hunters who turn in samples that come back positive for CWD are being notified as soon as possible, and any hunter can check www.arkansascwd.com to look up their sample’s status to have some added piece of mind. Biologists will work with hunters to collect and dispose of any meat from CWD-positive animals and reinstate their game tag if possible.

“If a positive sample is returned from a county which doesn’t currently have CWD, we will follow our standard protocol and confirm that sample through an additional test,” Gray said. “If that test also comes back positive, we will issue a release to make sure hunters in that area are informed.”

Gray says the AGFC’s partnership with taxidermists around the state continues to be invaluable to both the hunters and the agency.

“Last year we worked with taxidermists to gather samples from deer turned in to be mounted, but this year we’ve really tried to advertise to people that any deer can be taken to one of our participating taxidermists to have a CWD sample pulled for free,” Gray said. “We don’t have the manpower to pull samples all over the state throughout the entire deer season, so this partnership really helps give hunters peace of mind about their deer and helps us continue to monitor for the disease outside the focal area, where we know we have it.”

Any hunter who harvests a deer still can have the animal tested by taking the head with about 6 inches of neck attached to one of the participating taxidermists listed on www.arkansascwd.com.

CWD is a fatal neurological disease that affects members of the deer/elk family. It was first described in 1967 in Colorado and since has spread to 23 additional states, Canada, South Korea, and Norway. It was discovered in Arkansas in February 2016, and has since been found in 288 deer or elk in Arkansas after thousands of deer have been tested from across the state.

It is similar to “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. Infected animals will not show signs of disease at first, but late in the disease process, they will be thin and may demonstrate weakness, abnormal behavior, excessive thirst or drooling.

There has been no confirmed case of CWD affecting humans or livestock, but with an abundance of caution, the Centers for Disease Control recommends hunters test their harvested game and warns that people should not consume any deer or elk known to have CWD.
