In an effort to prevent the spread of highly pathogenic avian influenza in dairy cattle, Wisconsin is requiring Influenza A testing prior to movement of lactating dairy cattle to fairs or exhibitions effective June 19.
USDA has recommended that measures be taken to minimize the potential spread of influenza.
HPAI (H5N1) has been detected in dairy cattle in 12 states including Iowa, Michigan, and Minnesota. In addition to the USDA Federal Order that requires Influenza A testing for interstate movement of dairy cattle, today’s announcement will limit the risk of commingling infected animals. Wisconsin does not have an HPAI case in dairy cattle at this time.
In order to move lactating dairy cattle to fairs or shows within the state, producers must receive a negative test for Influenza A virus at an approved National Animal Health Laboratory Network laboratory with samples collected no more than 7 days prior to movement to the fair or exhibition.
This testing is available to producers at no cost through USDA APHIS at NAHLN laboratories. Producers may also apply for reimbursement of shipping and veterinary fees for the collection of samples.
This intrastate order requiring a negative Influenza A test prior to traveling to a show or exhibition will remain in effect until 60 days after the last detection of H5N1 in cattle herds in the U.S.
Dairy producers and those working with dairy are strongly encouraged to continue practicing strict biosecurity to protect their herds.
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).
