Dairy Cattle & Highly Pathogenic Avian Influenza (HPAI)

Update on Lactating Dairy Cattle Movement

4/30/2026 - The United States Department of Agriculture (USDA) has shared an important update about moving lactating dairy cattle across state lines.

At this time, pre-movement influenza testing is no longer required for lactating dairy cattle coming from states that the USDA has officially declared free of livestock Highly Pathogenic Avian Influenza (HPAI).
You can read the full USDA update.

However, some states may still have their own testing rules.
Veterinarians and producers should always check with the destination state’s animal health office before moving animals.
The USDA also provides weekly updates, including:

The New England Fairs and Shows CVI Agreement (March 27, 2026) will be updated to match this new USDA guidance. Once the updated version is ready, the revised New England Fairs and Shows CVI Agreement will be posted and available for download in the 2026 Animal Health Fairs Packet on the Maine Department of Agriculture, Conservation and Forestry Animal Health website.

Please watch for updates and continue to follow all current animal health rules to help keep livestock safe.

CVI Requirements

As noted in the APHIS Requirements and Recommendations for Highly Pathogenic Avian Influenza (HPAI) H5N1 Virus in Livestock, dairy cattle moving direct to slaughter on a CVI must have individual official identification recorded.

USDA’s final rule on Use of Electronic Identification Eartags as Official Identification in Cattle and Bison was released in April, 2024. During this transition window over the next 180 days metal, non-electronic identification (EID) tags for animal identification will continue to be allowed, but soon only RFID tags as the official eartag for use in interstate movement of cattle will be allowed.

DACF Animal Health can provide producers, veterinarians, and others with RFID tags for cattle. Before we can send tags, a Premises Identification Number (PIN, also commonly called a "Prem ID") is required. A PIN is a unique code that is permanently assigned to a single physical location.

USDA HPAI Cattle

On May 23, 2024, USDA released support options to include dairy producers whose herds have not tested positive for H5N1. Financial support will be available to:

  • Support biosecurity planning and implementation
  • Reimburse producers for veterinary costs associated with sample collection for H5N1 testing.
  • Offset shipping costs for influenza A testing at laboratories in the National Animal Health Laboratory Network.

More information is available here: USDA, HHS Announce New Actions to Reduce Impact and Spread of H5N1 | USDA.

Please note that we don’t yet have specifics from USDA on accessing this funding. As we receive additional information we will be sure to post it here. Feel free to reach out to us using the contact information at the bottom of this page.
