The USDA’s Animal and Plant Health Inspection Service (APHIS) suspended imports of live cattle and bison from Mexico on November 22, 2024, following the discovery of New World screwworm (NWS) near Mexico’s southern border. This action was taken to prevent the spread of NWS, a pest that poses significant risks to cattle health. Since the suspension, U.S. and Mexican authorities have worked together to develop enhanced screening measures for live animal imports.
Imports of Mexican feeder cattle are expected to partially resume during the week of January 20. This initial phase will proceed cautiously to allow for the implementation and testing of new safety protocols. Full-scale live animal imports are anticipated to follow at a later date as safety measures are refined and proven effective.
Several factors are influencing the reopening timeline. These include facility inspections, as protocol agreements are in place but require inspections and approvals for implementation. Additionally, animals will need to undergo a seven-day quarantine after health checks, ensuring they meet safety standards. The Santa Teresa, New Mexico, port has been prioritized for resuming operations, reflecting its importance in cross-border livestock trade.
The suspension has had a notable impact on the U.S. cattle market. An estimated 250,000 to 300,000 fewer cattle were imported during the suspension period, contributing to higher feeder cattle and calf prices in the United States. Despite these disruptions, live animal movements are expected to normalize following the initial reopening.
