Cattle and Bison Movement

​
Movement Alert: New World Screwworm (NWS) has been identified in the southern U.S. It has not been identified in Wisconsin. In response to cases of NWS​ in other states, Wisconsin has additional requirements for warm-blooded animals moving from states with active NWS infested zones. Visit the NWS website for additional information on movement requirements and resources.

​​​​​​​​​​​​​​Highly Pathogenic Avian Influenza (HPAI) ​Detections in Cattle​

Effective April 27, 2025, the U.S. Department of Agriculture (USDA) updated the Federal Order designed to reduce the risk of HPAI spreading among cattle and poultry. The updated Federal Order allows the interstate movement of lactating dairy cattle without individual influenza A tests from states with 'Unaffected' state status under the National Milk Testing Strategy. Check your state status.​ 

For lactating dairy cattle from states with ‘Affected’ or ‘Provisionally Unaffected’ status, the Federal Order continues to require: 
  • ​Mandatory influenza testing for interstate movement of individual dairy cattle: 
    • ​A negative influenza A test for individual lactating dairy cattle is required prior to import. 
    • For imports of more than thirty (30) lactating dairy cattle moving in a group, contact the department. 
    • For imports of lactating dairy cattle from herds actively participating in the USDA HPAI Dairy Herd Status Program, contact the department. 
    • For beef cattle and other classes of dairy cattle, there are currently no influenza A testing requirements. Future requirements, if any, will be based on scientific factors concerning the virus and its evolving risk profile. 

Access a summary of additional requirements.

Additionally, cattle entering the state must meet import requirements which in most instances will include a certificate of veterinary inspection (CVI), official identification, and may include other testing. See "Import Rules by State" below. Animals included on the CVI should not be known to be infected with or exposed to contagious diseases, or showing signs of contagious or infectious disease, including highly pathogenic avian influenza (HPAI). For further information on the current situation in cattle, utilize the DATCP webpag​e on HPAI in Cattle.​

Additional Considerations for Cattle and Bison

  • The cattle and bison requirements are for bison and domesticated cattle breeds [Bos taurus or Bos indicus (such as Zebu and Brahman)].
  • For bovid animals that are not bison or domesticated cattle breeds such as yaks, water buffalo, and antelope species, please visit the exotic species webpage and click on "Exotic Ruminants".
  • Cattle from quarantined herds are ineligible for import into Wisconsin.
  • Lactating dairy cattle from herds with a positive influenza test result within the last 30 days are ineligible for import.
  • Lactating dairy cattle with clinical signs consistent with influenza are ineligible for import.
  • If you wish to import animals from several different states, or if the animals have been in the state of origin for fewer than 120 days, please contact us.​
  • No M-branded bovines/cattle from other states may be imp​orted to Wisconsin except directly to a slaughter facility. 
  • For bovines that are part of a rodeo, circus,​ or menagerie, also visit the circuses, rodeos, and menageries webpage.
