The state of Wisconsin is now requiring a negative highly pathogenic avian influenza (HPAI) (H5N1) test in order for exhibitors to showcase lactating dairy cows at local fairs and exhibitions within the state. This comes off the heels of a recent announcement made by the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP), stating that the requirement will go into effect on June 19.
According to Wisconsin officials, producers wishing to exhibit lactating dairy cows must receive a negative test for Influenza A at an approved National Animal Health Laboratory Network Lab, with samples collected no more than seven days prior to the event.
Currently, the tests are available at no cost through the USDA Animal and Plant Health Inspection Service (APHIS). Officials say the order will remain in place until 60 days after the last detection of the pathogen in cattle herds in the U.S.
DATCP notes that it is important to check requirements prior to importing animals from any state, as requirements can change. Requirements such as official identification and certificates of veterinary inspection (CVIs) help ensure cattle entering Wisconsin are healthy prior to import.
In summary, exhibitors wishing to exhibit lactating dairy animals at Wisconsin fairs and exhibitions should know the following:
- Lactating dairy cattle must receive a negative test for Influenza A virus at an approved National Animal Health Laboratory Network (NAHLN) laboratory prior to moving to fairs or exhibitions.
- The samples must be collected no more than 7 days prior to movement to the fair or exhibition.
- Testing is available to producers at no cost through USDA APHIS at NAHLN laboratories.
- Producers may apply for reimbursement of shipping and veterinary fees for collection of samples.
- This intrastate order requiring a negative Influenza A test prior to travelling to a show or exhibition will remain in effect until 60 days after the last detection of H5N1 in cattle herds in the United States.
