Chronic wasting disease was reported at farms in three Wisconsin counties last month, according to releases from the Wisconsin Department of Agriculture, Trade and Consumer Protection.
An elk from a breeding farm in Sauk County tested positive for chronic wasting disease, according to a June 25 release from the DATCP. The farm, which has 15 elk, has been quarantined. No animals may move in or out of the farm.
A white-tailed deer from a breeding farm in Marinette County also tested positive for CWD, DATCP reported June 18. The farm, which had not been enrolled in the CWD Herd Status Program since May 2017, has been quarantined. The farm contains 320 whitetail deer, according to the owner's most recent registration.
The depopulation of an Iowa County deer farm in May 18 revealed that of the 79 whitetail deer old enough to test, 21 tested positive for CWD, according to the DATCP. The farm had been quarantined since October 2017, after a CWD-positive deer shot on a hunting ranch in Waupaca County was traced back to the Iowa County farm. In total, 103 whitetail deer on the Iowa County farm were depopulated.
CWD is a fatal, neurological disease of deer, elk and moose caused by an infectious protein that affects the animal's brain. Testing for CWD can only be performed after the animal's death.
Gov. Scott Walker pushed in May for more aggressive rules to contain the spread of CWD in the state, including a prohibition on the movement of live deer from CWD-affected counties, enhanced fencing at deer farms in the state and a ban on the movement of carcasses from CWD-affected counties.
