A quarantine has been lifted on a Bayfield County hunting ranch that was depopulated in 2018 in response to a positive chronic wasting disease test in Washington County.

With no remaining deer on the Copper Hills Hunting Hunting Preserve near Oulu and no evidence of disease, the Wisconsin Department of Agriculture, Trade and Consumer Protection announced the release of the quarantine Friday, May 10.

The hunting ranch was placed under quarantine March 7, 2018, when a trace investigation showed the animals came from a Washington County deer farm that tested positive for CWD. The deer had been transferred to the Oulu farm in December 2017 and 2018 prior to the positive CWD result in Washington County.

CWD was not detected in any of the Bayfield County deer, and animal health officials have found no remaining deer on the property over the past year.

CWD is a fatal neurological disease of deer, elk and moose. Testing for CWD can only be performed after the animal's death. More information about CWD is available at https://datcp.wi.gov/pages/programs_services.
