Frequently Asked Questions for Hunters

Why test for CWD?

  • Testing deer and other susceptible species for CWD allows wildlife biologists and animal health officials to get a clearer picture of the prevalence and distribution of the disease across Texas.
  • Proactive monitoring improves the state's response time to a CWD detection and can reduce the risk of the disease further spreading to neighboring deer populations. With each discovery of a new CWD-positive area in the state, CWD zones are established as a strategy to manage and contain the disease.
  • Testing within established CWD zones will help determine the geographic distribution and prevalence of the disease or, in some cases, confirm that the disease has not been established outside of captive-deer breeding facilities.

How do I know if I am required to have my deer tested?

  • Testing all harvested susceptible species is required if harvested within the boundaries of one of the CWD zones. Since these CWD zones change, it's best to consult the TPWD website for the specific area of your hunt to determine if testing is required. Hunters who harvest mule deer, white-tailed deer, elk or other CWD-susceptible exotic species within a CWD Zone where mandatory sampling is required must have their animal tested for CWD.
  • Hunters are required to bring their harvested animal to the designated check station for that CWD zone within 48 hours of harvest.
  • To see if your hunting location is in a CWD zone, see the CWD zone map.
