USDA Updates on HPAI

Animals moving interstate to an exhibition, show, or sale may pass the 7-day testing window; is it possible to skip additional testing to return to the first farm?

These animals may travel to their home herd using the same negative test result provided the exhibition, show, or sale does not exceed 10 days of length.
Limit animal comingling of animals and follow biosecurity protocols.
Please check with each exhibition event to understand individual guidelines in place for dairy cattle.
