DNR Confirms CWD In Wild Deer In Trempealeau County

MADISON, Wis. – The Wisconsin Department of Natural Resources (DNR) confirms a wild deer tested positive for chronic wasting disease (CWD) in Trempealeau County. The deer was harvested in the town of Hale. 

This detection will cause the following:

• Trempealeau and Jackson counties will renew the baiting and feeding bans already in place.
• Eau Claire County currently has a baiting and feeding ban in place from positive detections within the county. The ban in Eau Claire is not renewed by this detection because it is longer than the two-year ban that would result from this detection.

The deer was a hunter-harvested 3-year-old doe and is the first confirmed wild deer CWD-positive detected in Trempealeau County.

State law requires that the DNR enact a three-year baiting and feeding ban in counties where CWD has been detected, as well as a two-year ban in adjoining counties within 10 miles of a CWD detection. If additional CWD cases are found during the lifetime of a baiting and feeding ban, the ban will renew for an additional two or three years.

The DNR also reminds the public that it is illegal to hunt over an area previously used for legal baiting and feeding until that area is completely free of bait or feed for 10 consecutive days.

More information regarding baiting and feeding regulations is available on the DNR’s Baiting and Feeding webpage.

Baiting or feeding deer encourages them to congregate unnaturally around a shared food source where infected deer can spread CWD through direct contact with healthy deer or indirectly by leaving behind infectious prions in their saliva, blood, feces and urine.

Hunters Can Help

The DNR asks deer hunters in Trempealeau, Jackson and Eau Claire counties to help with efforts to identify where CWD occurs on the landscape by having their deer tested for the disease. The collection of CWD samples is essential for assessing the presence of CWD in the deer population across the state.

In addition to submitting samples for CWD testing, hunters are also encouraged to properly dispose of deer carcass waste by locating a designated dumpster, transfer station or landfill location. Proper carcass disposal helps slow the spread of CWD by removing potentially infected deer carcasses from the landscape. A map of CWD sampling and carcass disposal locations is available on the DNR’s CWD sampling webpage.

CWD is a fatal, infectious nervous system disease of deer, moose, elk and reindeer/caribou. It belongs to the family of diseases known as transmissible spongiform encephalopathies (TSEs) or prion diseases. The DNR began monitoring the state's wild white-tailed deer population for CWD in 1999. The first positives were found in 2002.
