- Regulations · CWD and diseaseDeer with CWD shed prions in urine, and lure rules differ by stateLab studies found prions in urine from CWD-infected whitetails, with detection tied to genotype and disease stage. Virginia and Vermont ban natural urine lures, and Pennsylvania lifted its outdoor ban for 2026-27.
- Regulations · CWD and diseaseAmong Wisconsin's 21 Counties Without a CWD Detection, Median Testing Was 60 Deer for 2025Since 1999, each county has tested at least 371 deer. During the 2025 CWD year, county samples ranged from 20 to 183. Ten missed the 59-deer cutoff for excluding 5% prevalence; all missed the 299 needed to exclude 1%.60median deer tested in 2025 in Wisconsin counties with no CWD detection
- Regulations · CWD and diseaseCWD Areas: A Hunter's Plan for Cooling, Sampling, Transport and Carcass WasteWild CWD appears in the USGS county records for 37 states, including 76% of Nebraska's counties. Here is the sequence to follow after a kill, using agency-published timing and three studies that inform venison handling and carcass disposal.37states with wild CWD detections, per the USGS release
- Regulations · CWD and diseaseEHD and CWD: Recognizing the Differences in DeerThe time of year, physical signs and circumstances in which deer are discovered distinguish hemorrhagic disease from chronic wasting disease. County harvest figures cannot distinguish the diseases: decreases of at least 15% from the preceding season were about equally common in Wisconsin's 11 highest-CWD counties and the 50 other counties examined.63Illinois counties with a harvest drop of 15% or more in 2013
- Regulations · CWD and diseaseTwo States, Opposite Bets: How Wisconsin and Missouri Manage CWDWisconsin ramps up CWD efforts with extensive sampling and generous antlerless harvest rules. For 2026 to 27, Missouri drops its CWD zone, antler-point limits and separate CWD firearms portion. Here is how their policies compare.83counties in Missouri's CWD zone for 2025 to 26
- Regulations · CWD and diseaseThe Two-Disease State: Mapping Michigan's Bovine TB and CWDMichigan's fight against both deer diseases is rare among states: bovine tuberculosis is entrenched within its northeast Lower Peninsula, while chronic wasting disease surveillance spans the Lower Peninsula and the Upper Peninsula.18Michigan counties with confirmed CWD as of February 2026
- Regulations · CWD and diseaseThe Density Paradox: Wisconsin's High-Harvest Farmland Is Its SickestWisconsin's Southern Farmland zone has high rates of harvest registration, and every license includes antlerless harvest authorizations at no cost for use in farmland zones. Southern Farmland is also the center of the state's CWD problem. That leaves a paradox: the land hunters want to hunt most is where Wisconsin most needs to reduce deer numbers.12.4deer registrations per square mile in Central Farmland, 2024
- Regulations · CWD and diseaseOne in Three: Wisconsin's CWD, RecalculatedWisconsin's headline figure puts lifetime positivity among tested deer at about 5%. Pooling twenty-six years masks a rising rate. In 2025 sampling-year tests, 11.1% were positive; roughly a third were positive in the southern core.35.7%CWD positivity in Richland County in 2025
- Regulations · CWD and diseaseMissouri's CWD Doesn't Creep. It Jumps.933 positive deer by kill section, 2011 to 2025. Three years: positives within half a mile of a Macon County spot. Most mapped positive counties (39 of 55) first detected CWD over 75 miles from origin; farthest about 240 miles.39 of 55mapped counties whose first detection landed over 75 miles from the start
- Regulations · CWD and diseaseThe On-Ramp: Captive Deer and the 69-County Watch ListDeer carry CWD a few miles yearly; people move it much farther. 58% of counties with infected captive facilities have wild CWD. April 2025 data record captive CWD but no wild detection in 69 counties. Start looking there.58%of captive-CWD counties also have wild CWD
- Regulations · CWD and diseaseThe Crash That Hasn't Come: CWD Prevalence vs. the Wisconsin HerdThrough 2024, Wisconsin's core had less decline in crashes than counties below 5% prevalence. Harvest dropped 7% against 3%, a small gap without a collapse. The lag still calls for caution.−6%median drop in collision rate in the highest-prevalence counties, 30% elsewhere
- Regulations · CWD and diseaseThe CWD Epicenter: Wisconsin's Southern Herd at the ThresholdDuring 2025 sampling, southern Wisconsin had 87% of CWD detections. Some southwest areas top 30% prevalence among adult bucks. DNR research sets the herd-decline threshold at about 29% in females. Spread north threatens northern herds.87%of Wisconsin's CWD detections come from the Southern Farmland zone
