The DNR announced that nine of 358 deer shot during a special August hunt in the zone had tested positive. One of the nine was shot about one mile northwest of Cross Plains and was close enough to the boundary of the zone so that it was expanded by 22 square miles.

The DNR has widened its eradication zone by 43% since May as more cases have been found. The bigger zone means that more deer will have to be killed.

Within the CWD eradication zone the total of infected wild deer is 40 out of 1557 tested, or a 2.57% infection rate.
