The Missouri Department of Conservation said seven of the nearly 7,700 free-ranging deer tested for Chronic Wasting Disease were confirmed to have the fatal disease.
The new cases –– three in Adair, two in Macon and one each in Linn and Franklin –– bring the total to 33 deer that had the disease since it was first discovered in 2010. Twenty-one cases were found in Macon County.
CWD infects only deer and other members of the deer family by causing degeneration of the brain. The disease has no vaccine or cure and is 100‐percent fatal. According to MDC State Wildlife Veterinarian Kelly Straka, the department’s CWD‐testing efforts focus mostly on deer harvested by hunters and deer removed by MDC staff and landowners from specific private properties in northeast, central and east‐central Missouri around where the disease has been found, along with a small number of sick and road‐kill deer.
Straka said MDC also conducts broader CWD testing around the state each year as part of its ongoing monitoring efforts. Nearly 2,700 of the deer tested last fall and winter were part of this broader CWD monitoring and the focus was on the southern half of Missouri. No deer from southern Missouri were found to be positive for CWD.
The conservation department has collected more than 51,000 tissue samples for CWD testing from all around the state since it began testing for the disease in 2001.
This coming fall and winter, MDC said it will increase its testing efforts in its CWD management zones. The management zones consist of 29 counties within or that touch a radius of approximately 25 miles from where the disease has been found. Counties in the CWD management zones are: Adair, Boone, Callaway, Carroll, Chariton, Crawford, Cole, Cooper, Franklin, Gasconade, Jefferson, Knox, Linn, Livingston, Macon, Miller, Moniteau, Morgan, Osage, Putnam, St. Charles, St. Louis, Randolph, Schuyler, Scotland, Shelby, Sullivan, Washington and Warren.
MDC will require hunters to present their deer for CWD testing at an MDC testing location if they harvest it in one of these 29 counties during the opening weekend of the fall firearms deer season Nov. 12 and 13. The testing is free and hunters can also get free test results.
“We are in the process of working out the logistics for this important CWD‐testing effort and will have more details this summer and fall,” explained Straka. “We will be providing several locations in each of the 29 counties to help make getting their deer tested as convenient as possible for hunters.”
MDC will also continue to work with meat processors and taxidermists in the 29 counties to provide free CWD testing during other parts of the upcoming deer‐hunting seasons. The department will also continue its broader ongoing CWD monitoring efforts with a focus on the northern half of the state for the upcoming season.
