As of Monday, April 29, 2024, USDA APHIS put into effect mandatory testing prior to interstate (across state lines) movement of lactating cattle via a federal notice issued last week. Testing for other classes of dairy cattle will continue to be evaluated as the situation evolves. Dairy farmers should continue to work with their herd veterinarian to monitor cattle and report any related symptoms. To report herds, veterinarians should contact DATCP at (608) 224-4872 (business hours) or (800) 943-0003 (after hours and weekends).

Stay Informed

Please continue to visit USDA, DATCP, NMPF, and CDC websites for updates and recommendations.
