Overview

• USDA Secretary Brooke Rollins ordered an immediate halt to phased live cattle, bison and horse imports from Mexico on July 9.
• The suspension follows Senasica’s report of a new New World screwworm case in Ixhuatlán de Madero, Veracruz.
• US officials have faulted Mexican authorities for not providing accurate and timely information on the pest’s spread.
• The USDA is insisting on strict animal-movement controls, expanded trapping and surveillance and plans to reinstate sterile-fly production in Metapa, Chiapas, while building a contingency facility in south Texas by mid-2026.
• Border closures have cost over $400 million this year as Mexican live-cattle exports fell 64 percent in volume and 53 percent in value, prompting the National Agricultural Council to pledge full binational cooperation.
