Recent detections of New World screwworm (Cochliomyia hominivorax) in the US began with USDA APHIS confirmation of myiasis in a Zavala County, Texas calf on June 3, 2026, linked to northward spread from Mexico and Central America. As of mid-August 2026, APHIS data show 44 livestock cases (cattle, goats, sheep) confined to Texas counties plus one dog case in Lea County, New Mexico; no confirmed livestock infestations have occurred outside Texas. Enhanced surveillance via over 100 NWS-specific traps, drone flights, wildlife exams, and sterile insect releases continues across border states, with case counts updated daily on screwworm.gov. Key upcoming factors include the August 24, 2026 phased reopening of select southern ports for Mexican livestock imports and ongoing model runs assessing dispersal risk under current quarantine and movement controls. Trader sentiment reflects the absence of further geographic spread in livestock to date amid active containment.
