Mexico Reports Cattle Screwworm Contained in South, Signals Readiness to Restart U.S. Exports

Officials cite 941 active cases concentrated in the south, with sterile-fly releases under a joint plan with the United States.

Overview

  • Authorities report 941 active cases, equal to about 0.003% of the national herd, with 99.9% located in the south–southeast and none currently active in northern states.
  • Mexico’s field operation includes inspections and treatments for 2.2 million animals, reinforced checkpoints, and 1,195 personnel deployed for surveillance and rapid response.
  • A Senasica–APHIS Action Plan signed on August 19, 2025 guides binational inspection, trapping, in-transit verification, and large-scale release of sterile flies.
  • Mexico says exports to the U.S. can resume under agreed protocols, while reporting from Excélsior notes the border remains closed for now, with estimated losses of over $25 million per month.
  • Funding tightens with a 10.7% cut to Senasica’s 2026 budget, even as a $51 million sterile-fly plant in Chiapas is slated to start operations in the first half of 2026 with capacity for 100 million flies per week.
