**Current USDA APHIS surveillance data through mid-August 2026 show all 44 livestock detections confined to Texas counties, with the single New Mexico case limited to a dog.** The outbreak, linked to northward spread from Mexico since late 2024, prompted sterile fly releases, 20-km infested zones, movement controls, and temporary southern port closures. No confirmed livestock cases have occurred outside Texas, supporting trader consensus around containment via the sterile insect technique and active trapping across border states. Key variables include ongoing model runs for fly dispersal efficacy, any new detections reported on screwworm.gov dashboards, and surveillance updates from Texas and New Mexico partners that could shift odds if cases appear in adjacent states’ livestock.

Any laboratory-confirmed screwworm infection identified within a U.S. state other than Texas will qualify, regardless of where exposure or symptom onset occurred.
The primary resolution source for this market will be official government information (e.g., the CDC or USDA); however, an overwhelming consensus of credible reporting will also suffice.
