Overview
- The Metapa facility has reached 75% completion and is expected to start producing sterile flies by late June to support long-term suppression of the cattle screwworm.
- Plan Noreste, which deploys more than 350 field technicians in Tamaulipas, Nuevo León and San Luis Potosí, has resolved 65% of regional incidents as of April 24, with 459 cases deactivated and 242 under specialized care.
- Mexico and the U.S. are releasing sterile flies across the affected states and along an 88.5‑kilometer strip in Texas, using a method that pairs non‑fertile males with wild females so no larvae develop and the pest declines.
- Emergency operations centers opened in March in Ciudad Victoria and San Luis Potosí, backed by sanitary sweeps on over 1,600 routes, checks on more than 80,000 animals, tighter livestock movement controls and training for about 10,000 producers plus 100 wildlife specialists.
- Since November 2024, authorities have logged 21,131 screwworm detections nationwide and resolved 93.8% of them, a scale that shows the risk to ranchers’ animals and to Mexico’s export-ready animal‑health status.
