The U.S. Department of Agriculture (USDA) is continuing its phased reopening of southern border ports for livestock imports from Mexico. The latest step came on October 26, 2026, with the reopening of the Columbus, New Mexico, port of entry for cattle imports.
The restrictions were originally introduced to prevent the spread of New World screwworm (NWS), a pest that can severely impact livestock health. USDA has taken a cautious approach to restoring imports while ensuring protective measures remain effective.
The reopening of the Columbus port marks the third phase of the agency's plan. Earlier, the Douglas, Arizona, port reopened on August 24, followed by the Santa Teresa, New Mexico, port on September 24 , 2026.
USDA has also resumed imports of horses and other equines from Mexico. For now, these animals may only enter the United States through the Santa Teresa port under enhanced biosecurity requirements.
Before export, horses must undergo inspections and treatment procedures in Mexico. Once they arrive in the United States, they are required to complete a seven-day quarantine period before being released.
The quarantine process for equines will take place at USDA-approved facilities on the U.S. side of the border. Meanwhile, quarantine facilities previously operating in Mexico will remain closed as USDA evaluates the updated safeguards.
Officials say the gradual reopening allows the agency to assess whether the new inspection and quarantine measures are working effectively. Limiting equine imports to a single entry point also helps identify and address potential challenges before expanding operations.
The phased strategy is intended to support agricultural trade while maintaining strong protections against livestock diseases and pests. Producers, importers, and industry stakeholders are expected to benefit from the gradual restoration of cross-border trade.
USDA will continue monitoring the effectiveness of these protocols as reopening efforts move forward. Future decisions on additional border crossings will depend on the successful implementation of current biosecurity measures.
