The Office of Management and Budget (OMB) has received a notice from USDA's Animal and Plant Health Inspection Service (APHIS) on the use of radio frequency identification (RFID) tags as “official identification in cattle and bison.”
In July 2020, APHIS published a notice seeking comment on moving to using RFID tags as the sole official eartags used in interstate movement of cattle and bison. Comments were due by Oct. 5, 2020. The agency proposed that starting Jan. 1, 2022, they would no longer approve venders to use the official USDA shield in producing metal eartags or other eartags that do not have RFID components.
They also suggested that starting Jan. 1, 2023, RFID tags would be the only identification devises for cattle and bison, but indicate cattle and bison with metal tags in place before that date would be grandfathered in.
Presumably the notice under review would finalize APHIS' plans on this topic.
