Deer in Northern Illinois Test Positive for CWD, Free Testing Available to Hunters

As the 2024 deer hunting season approaches, the Illinois Department of Natural Resources (IDNR) is reminding hunters to take advantage of free chronic wasting disease (CWD) testing for their harvested deer.

Free Testing for Chronic Wasting Disease (CWD) Available

CWD, a fatal neurological disease affecting deer and elk, remains a significant concern for Illinois' deer population, particularly in the northern counties.

First identified in Boone County in 2002, CWD has since spread across a 21-county area in the northern part of the state. Since its discovery, more than 170,000 deer have been tested statewide, with over 2,100 confirmed cases.

While CWD has no known impact on human health, agencies such as the Centers for Disease Control and Prevention (CDC) and the World Health Organization (WHO) advise against consuming CWD-positive venison.

Testing Locations and Methods

Hunters are encouraged to have their deer tested, especially if hunting in CWD-positive counties.

The IDNR offers multiple options for testing, including self-serve drop-off sites, participating vendors such as taxidermists and meat processors, and on-site testing at mandatory firearm deer check stations.

Hunters can locate testing sites via the Hunt Illinois app or the IDNR website.

Firearm Season and Results

During the firearm seasons on November 22-24 and December 5-8, hunters in CWD counties can have their deer tested at check stations, where biologists will collect samples.

Hunters can expect results within two to four weeks, with priority given to counties with confirmed CWD cases.
