Humphreys County, Tennessee, is now positive for chronic wasting disease (CWD), the Tennessee Wildlife Resources Agency (TWRA) disclosed in a press release yesterday.
The hunter-harvested deer was the first in the county to test positive for the fatal neurodegenerative disease. Humphreys County is in the northwest quadrant of Tennessee, which just wrapped up its 2025-26 deer season over the weekend. The TWRA submitted roughly 11,000 samples for CWD testing during the season.
“Hunter's participation in CWD testing has been critical for the continued surveillance and monitoring of CWD throughout the state,” the release said. “Hunters were able to access CWD testing through participating taxidermists and meat processors or by using drop-off freezers.”
The Tennessee Fish and Wildlife Commission will meet in March to finalize any deer-management changes prompted by the discovery, the release said.
CWD found in 36 US states
Caused by infectious misfolded proteins called prions, CWD affects cervids such as deer, elk, and moose. Since it was first documented in 1967 in a captive mule deer at a Colorado research facility, CWD has spread to at least 36 states, five Canadian provinces, South Korea, Finland, Norway, and Sweden.
Hunter's participation in CWD testing has been critical for the continued surveillance and monitoring of CWD throughout the state.
There is no vaccine or treatment for CWD. While no human infections have been documented, health officials warn against eating the meat of sick or infected cervids and urge caution when handling carcasses.
