The second confirmed case of New World screwworm that was confirmed in Grant County on September 17, 2026, has now become inactive.  The infestation was found in a horse with a leg wound.  The horse had never left the property, nor had any of the other animals or people, therefore the case was determined to be locally acquired.  An infested zone and surveillance zone were established right away and will remain in place for at least 3 to 4 lifecycles of the NWS fly.  See screwwormNM.org to view the zone map and additional updates.
