Overview
- Tamaulipas reported its first gusano barrenador del ganado case in Llera in a six-day-old calf with an umbilical lesion, marking the most northerly active detection roughly 306–317 km from the U.S. border.
- Sader and Senasica inspected 10 nearby production units and 325 animals with no additional positives, verified that the 21 cattle on the affected premises were clear, reinforced trapping and found no GBG flies, and coordinated with APHIS for sterile-fly releases.
- Analysts warned the Tamaulipas finding could complicate efforts to resume U.S. imports of Mexican feeder cattle, a trade already curtailed in 2025 with estimated sector losses of about $642–650 million.
- Authorities in the State of Mexico confirmed the first local case in a goat in Tlatlaya and activated preventive surveillance, producer training, and wound-care guidance across the high-priority southern region of the state.
- Nationally, officials reported hundreds of active infections across multiple species and states at year’s end, and a binational sterile-fly plant in Metapa, Chiapas, is slated to start in early 2026 with capacity of about 100 million flies per week.
