**USDA surveillance data through early August 2026 show all confirmed New World screwworm (Cochliomyia hominivorax) livestock cases remain limited to Texas counties, with the single New Mexico detection occurring in a dog rather than livestock.** This geographic pattern, combined with intensified sterile insect technique releases and southern border port closures, underpins current market-implied probabilities around 36% for an August 30 livestock case beyond Texas. Ongoing APHIS dashboard updates track individual animal confirmations by county and species, while model-based risk assessments guide sterile fly dispersal zones. Key upcoming catalysts include the August 24 phased reopening of the Douglas, Arizona port and continued weekly case reporting that could signal northward spread or successful containment before fall livestock movements intensify.

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.
