28 new cases: MDC tests reveal more deer with CWD

The Missouri Department of Conservation reports that 28 more deer from 11 Missouri counties have been found to have chronic wasting disease. This brings the number of cases of the deadly deer disease in Missouri to 103 since 2012.

None of the infected deer were from Ozark County. However, one of the 28 newly identified CWD deer was taken in Taney County, Ozark County’s neighbor to the west.

CWD is a deadly illness in white-tailed deer and other members of the deer family, called cervids. The disease is spread from deer to deer through direct contact and through contact with soil, food and water that have been contaminated through feces, urine, saliva or carcasses of infected deer. CWD kills all deer and other cervids it infects. 

The latest CWD-positive deer were from these counties: Adair (2), Crawford (1), Franklin (5), Jefferson (1), Linn (2), Macon (4), Mercer (1), Oregon (3), Ste. Genevieve (7), Stone (1) and Taney (1).

The results come after MDC collected tissue samples for CWD testing from more than 28,000 deer over this past summer and throughout the fall  2018 deer-hunting season. That number includes more than 20,000 tissue samples collected during MDC’s opening weekend “mandatory CWD sampling” in 31 designated counties in or near where the disease has been found. Ozark County was one of those counties. So far, CWD has not been found here.

 “Eight of the CWD detections were from hunter-harvested deer sampled by taxidermists or meat processors, who are all very important partners in helping us find cases of CWD,” said MDC wildlife disease coordinator Jasmine Batten. “Of the remaining 20 positives, 15 were from hunter-harvested deer sampled at our mandatory sampling stations, four were from hunter-harvested deer sampled by MDC staff outside of opening weekend through our voluntary sampling program and one was from a found dead deer.”

Batten added that CWD was detected in four new areas of the state this season:

Southwest Missouri in northeast Stone County near Reeds Spring and southern Taney County on the Drury-Mincy Conservation Area; southeast Missouri in west-central Oregon County near Alton; and  north- central Missouri in Mercer County north of Mercer, approximately 2 miles from the Iowa border.

MDC noted that hundreds of cases of CWD have been found in northwest Arkansas bordering southern Missouri, and CWD has also been found in Wayne County, Iowa, which borders northern Missouri.

“In the new areas, the number of CWD positives is low, indicating the disease was likely recently introduced in those locations,” said Batten. “Overall, where CWD occurs throughout the state, the number of infected deer also remains low, which indicates that CWD is relatively rare in the state – and we want to keep it that way. If left unchecked, CWD could dramatically decrease the overall health and number of deer in Missouri over time.”

MDC has tested nearly 130,000 deer for CWD since it began its efforts in 2001. For the most current CWD numbers and more information, visit the MDC website at mdc.mo.gov/cwd.

 

Next steps: Targeted culling

MDC is now focusing on managing CWD in the immediate areas where new and recent cases of the disease have been found. MDC staff are again working with landowners on a voluntary basis through mid-March in the immediate areas (approximately 1-2 square miles) around where recent cases of CWD have been found to harvest and test additional deer for the disease.

Batten added that MDC is modeling this management approach after similar effective efforts in Illinois, which “is showing success in stabilizing CWD prevalence through targeted culling and reports a steady 1 percent prevalence statewide over time. In contrast, since stopping its targeted-culling management efforts in 2007, the state of Wisconsin continues to see a steady increase in CWD prevalence. Some local areas of southwest Wisconsin are seeing over 50 percent of adult bucks with the disease.”

MDC staff and participating landowners have taken a total of about 4,600 deer through targeted culling since the department began the effort several years ago. Post-season targeted culling accounts for just approximately 4 percent of all CWD samples MDC has collected so far but has resulted in finding almost half of all CWD cases in Missouri.

Batten added that deer harvested through targeted culling that do not test positive for CWD are offered to the participating landowners or donated to the Share the Harvest Program for local food banks and food pantries. Deer that test positive for CWD are properly disposed of by MDC staff or meat processors.
