Des Moines, Iowa — Fourteen tissue samples from wild Iowa deer tested positive for chronic wasting disease, bringing the total deer testing positive to chronic wasting disease in Iowa to 44. The Iowa Department of Natural Resources is waiting for results on follow up tests for two suspect samples that could raise the total positives for the year to 16.  The deer tissue was collected primarily during the fall from hunter harvested and road killed deer.

The way that this disease moves, these results were not unexpected,according to  Todd Bishop, chief of the Iowa Department of Natural Resources Wildlife Bureau.

Eight positive deer were confirmed in Allamakee County, four in Clayton County, one (plus two suspects) in Wayne County and, for the first time, one in Dubuque County. The Dubuque County deer was a roadkill, 2-1/2 miles southeast of the city limits.

Bishop says hunters are doing an excellent job harvesting deer and providing samples in DNR’s priority areas, areas where the disease had been confirmed before. The DNR wants to slow this down as best they can while still having high quality deer hunting, hoping science can provide some solutions down the road, according to Bishop

More than 6,800 tissue samples have been collected during the 2018 deer season. The DNR contacted each hunter whose deer tested positive and offered to collect the meat and any remaining bones and tissue. Hunters turned over the meat in every case. The collected material was bagged, sealed, then disposed in a local landfill.

Chronic wasting disease was first confirmed in the Midwest in Wisconsin in 2001 about 75 miles from the Iowa state line, and has since been confirmed in every other state bordering Iowa. The Iowa DNR began monitoring for the disease in 2002 with an emphasis on counties nearest where it was confirmed in the wild and has tested more than 74,000 deer since. The disease was first confirmed in Iowa near Harpers Ferry in Allamakee County in 2013.

CWD is a neurological disease belonging to the family of diseases known as transmissible spongiform encephalopathies (TSEs) or prion diseases.  It attacks the brain of infected deer causing the animal to lose weight, display abnormal behavior, lose body functions and die. It is always fatal to the infected animal.

The Iowa DNR has more information about CWD and other infectious disease online at www.iowadnr.gov/cwd.
