Mexican anti‑barrenador campaign advances

Entities: New World screwworm (Cochliomyia hominivorax) · Claudia Sheinbaum · U.S. Department of Agriculture · Brooke Rollins · Chiapas sterile‑fly production facility

Overview

Mexico’s sterile‑fly programme against the New World screwworm is progressing. President Claudia Sheinbaum confirmed that releases of sterile male flies will start within two weeks, moving from the northern cattle‑producing states toward the south. The Chiapas production plant is already operating, initially outputting about 28 million flies per week with a goal of reaching 100 million by the end of 2026, and a newly evaluated strain is under Cofepris review.

The U.S. Department of Agriculture has scheduled a phased reopening of livestock border crossings, beginning with the Douglas, Arizona port on 24 August 2026, followed by additional points in New Mexico (Santa Teresa and Columbus) and later the Agua Prieta crossing in Sonora, with two further sites in Chihuahua. A formal letter from USDA Secretary Brooke Rollins confirmed the timetable.

The coordinated effort among Mexico, the United States and Panama aims to satisfy U.S. sanitary requirements, revive the cattle export trade, and mitigate the more‑than‑$1 billion economic loss caused by the year‑long suspension.
