Additional Facility in Pottawatamie County Under Quarantine for Chronic
The following a press release from the Iowa Department of Natural Resources
and Iowa Department of Agriculture and Land Stewardship regarding additional
chronic wasting disease detections at confined deer breeding facilities and the
continuing efforts being made to stop the spread of the disease.
DES MOINES – Five deer at a breeding facility in Pottawattamie County have
tested positive for chronic wasting disease (CWD) placing that operation under
Three of the five deer in Pottawattamie County along with a single
white-tail deer at a hunting preserve in Davis County – Iowa’s first confirmed
positive CWD sample – have been traced back to a breeding facility in Cerro
In addition, 14 deer from the breeding facility in Cerro Gordo County have
been sampled for CWD with one yielding a positive result for CWD. The Cerro
Gordo facility is also currently under quarantine meaning live animals are not
allowed to come or go from the operation.
After the first positive sample of the deer in Davis County was confirmed
in July, both the Iowa Department of Natural Resources (DNR) and Iowa Department
of Agriculture and Land Stewardship (IDALS) have been working to trace back deer
that have moved to and from the Cerro Gordo County facility.
Once the initial positive detection of CWD was found in Davis County, the
DNR worked with several other states that had clients of the facility to
determine which deer was the carrier of the disease. Through DNA testing, it was
determined that the affected deer had originated from the Cerro Gordo County
The DNR has regulatory authority on hunting preserves while IDALS regulates
captive breeding herds.
“It’s important for us to gather as much information as possible as to
where these deer have come from and gone to if we are going to be successful in
containing the spread of CWD. Our primary concern is to keep CWD from spreading
to the wild herd,” said Bruce Trautman, deputy director of the DNR.
The 330-acre Davis County facility is currently surrounded by an eight-foot
high fence and routine inspections are being conducted by the DNR to ensure the
integrity of the fencing system so that no deer are coming or going from the
The DNR will increase testing of wild deer in the area by working with
hunters and landowners to collect samples from hunter harvested deer beginning
this fall. A goal of 300 samples within a five-mile radius of the Davis County
facility has been established.
There is no evidence that CWD can spread to humans, pets or domestic
livestock such as pork, beef, dairy, poultry, sheep or goats.
Iowa has tested 42,557 wild deer and over 4,000 captive deer and elk as
part of the surveillance program since 2002 when CWD was found in Wisconsin.
CWD is a neurological disease that only affects deer, elk and moose. It is
caused by an abnormal protein, called a prion, which affects the brains of
infected animals, causing them to lose weight, display abnormal behavior and
lose bodily functions. Signs include excessive salivation, thirst and urination,
loss of appetite, progressive weight loss, listlessness and drooping ears and
The prions can attach to soil and spread the disease among deer. Chronic
wasting disease was first identified in captive mule deer at a research facility
in Colorado in 1967. Prior to the positive detection in Iowa, CWD had been
detected in every bordering state.

Diagnostic accuracy of rectal mucosa biopsy testing for chronic wasting
disease within white-tailed deer (Odocoileus virginianus) herds in North America
The overall diagnostic specificity was 99.8%. Selective use of antemortem
rectal biopsy sample testing would provide valuable information during disease
investigations of CWD-suspect deer herds.
*** Spraker suggested an interesting explanation for the occurrence of CWD.
The deer pens at the Foot Hills Campus were built some 30-40 years ago by a Dr.
Bob Davis. At or abut that time, allegedly, some scrapie work was conducted at
this site. When deer were introduced to the pens they occupied ground that had
previously been occupied by sheep.
