California disease risk map.
California has no documented wild CWD detections to date. CDFW maintains import restrictions on cervid carcasses from CWD-positive states and runs ongoing surveillance of harvested deer. Hunters returning from out-of-state hunts must comply with import rules.
Disease detections, management zones, and transport rules change. Cross-reference this page with California Department of Fish and Wildlife and the USDA APHIS distribution map before relying on it for hunting decisions.
California county detections
0 counties with seeded CWD records. The agency may have additional positive counties — verify before each hunt.
No county-level CWD detections currently seeded for California in our database. This is not the same as no detections existing — always cross-reference with the state wildlife agency and the USDA APHIS distribution map for current data.
Carcass transport rules
No statewide carcass transport restrictions for CWD currently apply since the state has no detections to date. Confirm the latest rules with your state wildlife agency before transporting harvest from out of state.
CWD testing
The state does not require CWD testing because it has no detections to date. Hunters who hunt in CWD-positive states should follow that state's testing requirements before transporting harvest home.
EHD activity in California
California has historically experienced rare EHD activity. EHD is a viral disease transmitted by Culicoides midges and is not transmissible to humans — meat from EHD-affected deer is safe to consume per state agency guidance. Outbreak years correlate with hot, dry conditions; localized die-offs can reduce hunting opportunity for a season but do not persist year to year the way CWD does.
