Overview
- Authorities confirmed a new active screw-worm case in Monterrey on Friday, the most northerly infection recorded so far in Mexico.
- Nuevo León now counts six cases since September, and recent infections in dogs point to local breeding rather than cases tied to cattle moved from the south.
- Mexican officials say talks with the United States on reopening some cattle crossings are very advanced after the first call between Foreign Minister Roberto Velasco and Secretary of State Marco Rubio raised the issue.
- Mexico is importing sterile flies and says a new sterile-fly plant in Chiapas will start producing in June as teams expand trapping and on-farm wound care to cut the parasite’s spread.
- SENASICA reports 20,028 total cases and 1,265 active nationwide, including 732 in cattle and 285 in dogs, and the ongoing export ban has driven heavy losses for ranchers and new quarantine upgrades at the Sonora border.
