Mexico Regulator Reports Drop in Active Screwworm Cases as Puebla Confirms 17 Infections

Overview

• Puebla authorities report 17 detections, mostly in the Sierra Negra, and have set up two sanitary fences with 12 brigades and eight itinerant verification routes.
• More than 2,300 producers in Puebla have received training and medicines, while outreach continues in markets and slaughterhouses.
• The farm bureau Ceagro urges tighter sanitary controls, noting past roadside checkpoints were removed and saying the pest’s arrival in the state was inevitable.
• Earlier reports cited a 32% rise in national infections between August 17 and September 13, but SENASICA now emphasizes a decline in active cases and notes 99.97% of recent cases remain in the south‑southeast.
• Longer‑term control plans include rehabilitating the Metapa sterile‑fly plant to begin operations in the first half of 2026, with $51 million in funding and capacity for 100 million sterile males weekly, as cattle exports to the U.S. remain severely curtailed after a May border closure.
