Wildlife managers report encouraging results in their efforts to keep chronic wasting disease out of the deer herd in Minnesota.
The Department of Natural Resources says none of the more than 2,300 deer sampled last year tested positive for the disease.
Tests on nearly 1,200 deer taken in the Pine Island area of southeastern Minnesota turned up no infected deer for the second year in a row. The only deer from that area that's tested positive to date was one discovered in the 2010 hunting season.
Deer also were tested as a precaution in east-central Minnesota, because the disease was discovered in nearby Wisconsin, and in the north metropolitan area, because a captive herd in North Oaks tested positive. All those tests came back negative as well.
