Minnesota’s only currently quarantined farmed deer herd in Crow Wing County continues testing deer harvested on the farm for Chronic Wasting Disease.

Disease not detected in latest round of CWD tests

Minnesota’s only currently quarantined farmed deer herd in Crow Wing County continues testing deer harvested on the farm for Chronic Wasting Disease.

The latest results released by the Veterinary Diagnostic Laboratory did not detect CWD in deer tissue samples.

The Minnesota Board of Animal Health quarantined the herd in December 2016 when two white-tailed deer tested positive for CWD.

When the herd was quarantined, it consisted of 110 white-tailed deer and 33 mule deer.

Samples have been taken from 51 white-tailed deer and five mule deer in the herd to date in 2017; all have been “not detected.” Despite the continued “CWD not detected” results, the herd remains quarantined and the owner is restricted from moving animals.

The Board will report any additional testing.

The owner continues to uphold a herd plan agreement with the Board and the USDA, and declined an offer of indemnity to depopulate the entire herd. Instead, the herd will remain under quarantine until 2021 when it expires.

“Deer remain on this farm, and as long as we continue receiving ‘CWD not detected’ results, we’ll stick to the herd plan we have with the owner,” said Board Assistant Director, Dr. Linda Glaser.

“We hope to keep this trend going, and obviously 2021 is a long time from now, so the chance of a positive test result remains on our radar.

If CWD is detected again in this herd, we will re-examine the herd plan with the owner.”

The Crow Wing County farm owner has made infrastructure improvements since the initial CWD detection in 2016.

The owner installed additional exclusionary fencing to prevent contact between the farmed deer and wild deer.

This practice is widely recognized to reduce the risk of disease spread.

CWD is a disease of deer and elk caused by an abnormally shaped protein, a prion, which can damage brain and nerve tissue.

There is no danger to other animal species.

The disease is most likely transmitted when infected deer and elk shed prions in saliva, feces, urine, and other fluids or tissues.

The disease is always fatal, and there are no known treatments or vaccines. Consuming infected meat is not advised.
