During an average week, 50,000 dairy cattle move across state lines here in the United States. Keith Poulsen, the director of Wisconsin’s Veterinary Diagnostic Lab says the testing requirement was the right call and can help stop the spread between states.
An outbreak of the virus in the U.S. poultry sector has been going on since early 2022, and researchers are hoping they can take what they have learned from those cases and apply it to what is happening with cattle.
So far, nine states have reported cases of HPAI in dairy cattle. None have reported any cases since the travel restrictions went into place. However, federal officials say the virus has likely been around cattle for some time, with tests showing an infection was likely present in one case late last year. The ag sector has been cautious since the first case, and NASDA says teamwork will help keep the industry safe.
