Overview
- The infection was found in a six‑day‑old calf in Llera, where SENASICA inspected the herd of 21 and confirmed no additional animals were affected.
- Targeted surveillance expanded to 10 nearby production units with 325 animals checked and no further positives, and trapping to date has not captured the pest in the area.
- Authorities say Tamaulipas becomes the 14th state with detections since late 2024, as the outbreak totals have surpassed 13,000 cases nationwide with hundreds currently active, largely in the south.
- USDA/APHIS and Mexican officials are coordinating immediate sterile‑fly releases to suppress local transmission, while trade analysts warn the finding could slow efforts to reopen U.S. imports of live cattle.
- Longer‑term control hinges on a new Metapa, Chiapas facility slated to produce up to 100 million sterile flies weekly in the first half of 2026, with producers in Chiapas also deploying low‑cost artisanal traps as an interim measure.
