Chronic Wasting Disease Surveillance

CWD has been detected in Inyo and Madera Counties. The Fish and Game Commission has adopted emergency regulations(opens in new tab) in response to these detections. All hunters who harvest a deer within zones D7, X9a, X9b, and X9c must provide a retropharyngeal lymph node or the head from their harvest for CWD testing.

Chronic Wasting Disease (CWD) is the most important disease affecting deer and elk populations in North America(opens in new tab). CWD was recently detected for the first time in California's mule deer. To protect California’s deer and elk populations, and our hunting traditions, we need your help.
