Tissue samples collected from more than 4,700 Iowa deer in 2010 and 2011 have all tested negative for chronic wasting disease (CWD).

The majority of the samples were collected during the fall firearms season from seven counties in northeast Iowa, which is the area nearest to the CWD outbreaks in Wisconsin and Illinois.

The DNR also focused on collecting samples in south central Iowa, north of the area where the positive CWD deer was found in the captive facility in Missouri.

Since 2003, Iowa has tested 38,031 wild deer and 1,350 captive deer and elk. All tests have been negative.
