This market will resolve to "Yes" if there is a case of Screwworm in any livestock animal in a state of the United States other than Texas confirmed between market creation and the specified date at 11:59 PM ET. Otherwise, this market will resolve to "No". 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.Recent USDA APHIS confirmations of New World screwworm in U.S. livestock began June 3, 2026, with initial detections in south Texas calves followed by additional cases including a goat in Gillespie County, marking geographic spread within the state but remaining confined to Texas as of June 10. A separate case was confirmed in a dog in New Mexico, though no livestock infestations have been reported beyond Texas borders. The parasite, eradicated domestically in 1966 via sterile insect technique, has advanced northward through Mexico amid an ongoing regional outbreak tracked by official surveillance. Containment now includes expanded sterile fly releases, active monitoring across border zones, and veterinary response protocols. Future case reports from USDA or state animal health agencies could directly influence resolution criteria tied to confirmed livestock detections outside Texas.
