New Mexico has confirmed a second case of New World screwworm in a horse in Grant County, prompting expanded surveillance, a 12.4-mile infested zone, and broader monitoring with increased fly-trapping and animal inspections to detect and contain any spread, while keeping most animal movements allowed unless risk is identified.
