A 3-year-old deer in Wisconsin tested positive for Chronic Wasting Disease, triggering a quarantine and investigation.

A 3-year-old buck at a Portage County, Wisconsin, deer farm has tested positive for Chronic Wasting Disease (CWD), prompting a quarantine and investigation by state and federal officials. The disease, caused by infectious prions, affects deer, elk, and moose but is not known to infect humans. Wisconsin’s DATCP oversees deer farms through registration and testing, and the farm’s status remains under review. Meanwhile, Illinois is launching an automated alert system for CWD test results, requiring hunters in 25 endemic counties to provide harvest location details to receive notifications and maintain eligibility for replacement tags.
