USDA's National Veterinary Services Laboratories (NVSL) has now confirmed the presence of HPAI (H5N1) in dairy herds in Idaho, Kansas, Michigan, New Mexico, North Carolina, Ohio, South Dakota, and Texas. Access the full list of H5N1 detections in livestock.
DATCP is closely monitoring this issue with state and federal counterparts. DATCP recently launched a HPAI (H5N1) in Cattle webpage to provide resources. Included in these resources are links to the updated recommendations from USDA Animal and Plant Health Inspection Service (APHIS):
As a reminder, DATCP encourages producers that notice unusual clinical signs in their cattle to work with their herd veterinarian. To report herds with unexplained symptoms, veterinarians should contact DATCP at (608) 224-4872 (business hours) or (800) 943-0003 (after hours and weekends).
Wisconsin does not currently have additional movement restrictions on cattle coming from states or counties impacted by this condition; however, cattle entering the state must meet the state's standard import requirements. Animals included on the certificate of veterinary inspection (CVI) should not be known to be infected with or exposed to contagious diseases, or showing signs of contagious or infectious disease, including the HPAI (H5N1) virus. Understanding of this disease continues to evolve and requirements may be updated as new information is received. Current import rules for cattle can be found on the DATCP: Cattle & Bison Movement webpage.
Dairies should continue to segregate sick cows; their milk should not enter the bulk tank. Per USDA, there is no concern about the safety of the commercial milk supply or consumer health as products are pasteurized prior to entering the market. Pasteurization has been proven to inactivate bacteria and viruses, like influenza, in milk. DATCP encourages producers to practice good biosecurity, including minimizing animal movements as much as possible and isolating new additions to the herd.
