A white tail doe infected with Chronic Wasting Disease was reported by state officials in October, according to Agriculture Department Spokeswoman Donna Gilson. The deer lived on a Portage County hunting preserve. After six weeks of negotiations with the herd's owner, the remaining 64 others were recently killed off.
"Our regulations require that when we find a positive case that the remainder of the herd be tested," says Gilson.
Gilson says there is no way to way to do "live testing" for the disease.
CWD is a disease that affects the brains of deer, elk and moose. It's believed to be spread through contaminated soil.
The area where the herd lived will be quarantined for five years. This is first case of a new herd infected on Wisconsin farm since 2005.
