USDA's Animal and Plant Health Inspection Service (APHIS) is continuing its phased reopening of southern border ports for livestock imports from Mexico, supported by enhanced safeguards against New World screwworm (NWS) and ongoing evaluations of animal health conditions.

On October 26, 2026, APHIS will reopen the Columbus, New Mexico, port of entry to cattle imports. If conditions continue to support safe trade and all required inspection arrangements and infrastructure are in place, the next port scheduled to reopen to cattle imports will be Nogales, Arizona, on November 30, 2026.

Additionally, on October 26, 2026, APHIS will resume the importation of equines from Mexico via land crossing through the Santa Teresa, New Mexico, port of entry.

Under APHIS' updated protocols, horses and other equines imported from Mexico will continue to undergo a rigorous inspection and treatment process prior to export, followed by a seven-day quarantine period before being released into the U.S.??

Equines entering through Santa Teresa will complete quarantine at a USDA-approved facility located on the U.S. side of the border. Quarantine facilities on the Mexican side of the port of entry will remain closed at this time.??

USDA is taking a measured approach to reopening equine imports. Beginning operations at Santa Teresa will allow the agency to evaluate the implementation of the updated safeguards and confirm they are working as intended before expanding to additional locations.??

Following this evaluation, USDA will consider resuming equine imports through other approved ports of entry and approved quarantine facilities, including USDA-approved facilities in Mexico, as conditions warrant and animal health safeguards continue to be met.??Additional information on equine import requirements is available on the APHIS website.

USDA will continue to assess conditions at additional ports of entry and will make further reopening decisions based on animal health risks, operational readiness, and the continued effectiveness of mitigation measures.
