Recent detections of New World screwworm (Cochliomyia hominivorax) in New Mexico, including a horse in Grant County, signal ongoing northward expansion from the June 2026 Texas index case linked to Central American resurgence. USDA APHIS reports over 50 U.S. confirmations, primarily in Texas livestock (cattle, sheep, goats) with limited New Mexico spread, amid sterile insect technique releases exceeding one billion flies and enhanced border surveillance. Trader focus centers on whether additional laboratory-verified livestock infestations occur outside Texas before October or December deadlines, given model projections of warm-climate suitability and animal movement risks. Upcoming APHIS dashboard updates and state quarantine reviews will provide key data on containment efficacy.

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.
