Wisconsin (WQOW) - New state data shows nearly 1/4 of the cases of CWD at Wisconsin deer farms were reported in just the last year.
According to the Wisconsin Department of Agriculture Trade and Consumer Protection, 405 cases of CWD have been reported at deer farms in the last decade.
More than 100 of those cases were brought to the state's attention just this past year.
According to state records, there are 338 registered deer farms and hunting ranches in Wisconsin.
Wildlife officials could not point to a single factor as to why there was a sudden influx in cases.
The disease is fatal for deer, moose and elk but experts say there is no evidence it can cause people to get sick.
