Disease not detected in latest round of CWD tests for farmed deer herd in Crow Wing County
ST. PAUL, Minn. — Chronic wasting disease was not detected in deer tissue samples from Minnesota’s only currently quarantined farmed deer herd, in Crow Wing County, according to the latest test results involving the herd.
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, according to a news release announcing the results Thursday, Nov. 9 by the Board of Animal Health, which added that it 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, the release said. 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 Dr. Linda Glaser, Board of Animal Health assistant director. “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 release said: 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, according to the release.
