Additional disease monitoring and management are planned after the Feb. 14 confirmation that chronic wasting disease has been found outside southeastern Minnesota.
When the Department of Natural Resources confirmed CWD in a wild deer in Crow Wing County, the test result marks the first time the fatal neurological disease has been found outside of the southeastern part of the state.
Previous discoveries of the disease in wild deer have been concentrated predominantly in Fillmore County, with additional discoveries in Houston and Winona counties in the past two months.
As a result of these discoveries, the DNR is planning additional disease response actions. Gov. Tim Walz is proposing new funding of $4.57 million over the next two fiscal years, with $1.1 million annually thereafter to combat the disease, including surveillance and response, enforcement, and outreach to landowners.
“We take every discovery of CWD very seriously,” said Sarah Strommen, commissioner. “It is our hope that we discovered the Crow Wing County infection early and can respond quickly with actions to eliminate the disease in this area. With this critical new funding, we will continue to work with private landowners, hunters and others to achieve our goal of maintaining a healthy deer herd and Minnesota’s treasured deer hunting experience.”
The Crow Wing County deer, an adult female, was found on Jan. 23 in Merrifield, north of Brainerd. A conservation officer responded to a report of a deceased deer. The DNR tests suspect deer when possible, especially in areas of high risk.
The DNR began surveillance around a CWD-positive captive cervid facility near Merrifield starting in the 2017 hunting season. Over the last two years, the DNR has sampled more than 8,600 deer in this north-central surveillance zone, with no previous detections of CWD-positive deer.
“Thanks to our deer hunters, we have done a lot of surveillance in this area over the past two years, and it’s our hope the disease is isolated within this area,” said Lou Cornicelli, wildlife research manager.
As next steps, the DNR will determine where deer are located in the area by working with conservation officers and wildlife staff, and conducting an aerial survey. The DNR also will explore the possibility of late-season deer removals, and work closely with the Board of Animal Health, which regulates the state’s captive deer and elk.
In the southeast, the DNR has also intensified its management efforts, adding several special hunts in late 2018 and early 2019 to identify areas of CWD-infected wild deer. During the January/February special hunts in deer permit area 346, a hunter harvested a wild deer in Winona County that tested positive for CWD.
The positive deer was a 1 1/2-year-old buck harvested 2.5 miles east of a Winona County deer farm that tested positive for CWD in 2017 and 8 miles from the wild CWD-positive deer in Houston County found this fall. It was the first detection of CWD in wild deer in Winona County since testing began in Minnesota in 2002.
Within the disease management zone in deer permit area 603, targeted culling through the U.S. Department of Agriculture Wildlife Services has removed 154 deer as of Feb. 12. Four were CWD-positive and results are pending for 35 deer.
In response to these detections, DNR will activate additional response steps that include conducting an aerial survey to determine deer distributions in the area and working with landowners on deer removal options.
