 Iowa has detected additional positive tests because of increased testing, and it is likely that we will continue to report new positives as more tests are conducted. The department encourages dairy farms not subject to mandatory testing to continue to voluntarily participate in testing to help with the broader research effort. Farms with cattle displaying clinical signs are required to report them. While the final details are still pending, the department encourages Iowa farmers to participate in USDA's Voluntary Herd Status Program.
