CWD Testing Requirements for Hunters: What You Need to Know
Chronic Wasting Disease (CWD) is reshaping how hunters transport harvested animals across state lines. Many states now have mandatory testing requirements and carcass transport restrictions that apply to hunters before, during, and after their hunt.
What Is CWD and Why Does It Affect Your Hunt?
Chronic Wasting Disease is a fatal prion disease affecting deer, elk, moose, and caribou. It spreads through direct contact between animals and through the environment. CWD has been detected in 32 states and 4 Canadian provinces as of 2025. There is no cure and no vaccine.
CWD does not currently pose a confirmed risk to humans, but the CDC recommends against consuming meat from CWD-positive animals.
How CWD Affects Hunters
Mandatory Testing Before Transport
Many states with CWD zones require hunters who harvest a deer or elk in an affected management unit to have the animal tested before transporting the carcass out of the zone or state. Testing is done at state check stations, cooperating taxidermists, or through mail-in sampling kits. Results typically take 3–10 business days.
Carcass Transport Restrictions
Most states with CWD regulations prohibit importing whole carcasses or high-risk parts from affected areas. Permitted items typically include: boned-out meat (no spinal column or brain tissue attached), antlers (cleaned), and processed or commercially packaged meat.
