Utah disease risk map.
Utah confirmed its first wild CWD detection in 2002. UDWR runs ongoing surveillance focused on mule deer in affected hunt units. Verify current testing requirements per hunt unit.
Disease detections, management zones, and transport rules change. Cross-reference this page with Utah Division of Wildlife Resources and the USDA APHIS distribution map before relying on it for hunting decisions.

From first publicly-reported detection to the most recent year on record. Verify current detection counts with Utah Division of Wildlife Resources.
Utah county detections
5 counties with seeded CWD records. The agency may have additional positive counties — verify before each hunt.

Carcass transport rules
If hunting in a CWD-positive area, follow your state agency's carcass transport rules — most agencies prohibit moving whole carcasses with brain or spinal tissue across designated zone boundaries. Verify the current rules with your state wildlife agency before transporting any harvest.
CWD testing
Most state wildlife agencies offer free or low-cost CWD testing of harvested deer at check stations or sample-drop locations during season. Contact the state agency for current testing locations and turnaround times.
EHD activity in Utah
Utah 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.
