Animal Disease Traceability (ADT) Program

USDA Rule for Traceability of Livestock Moving Interstate

On May 9, 2024, USDA-APHIS published into the Federal Register the Final Animal Disease Traceability Rule “Use of Electronic Identification Eartags as Official Identification in Cattle and Bison” making visually and electronically readable tags the only form of official identification for sexually intact cattle and bison 18 months of age and older, all rodeo, exhibition cattle, and dairy cattle moving interstate. This new rule will go into effect Nov. 5, 2024. USDA’s Final 2024 Animal Disease Traceability rule only changes the type of tag that can be used, it does not change the class of animals that are required to be tagged.
