Two additional cases of New World screwworm have been confirmed in New Mexico, raising concerns about the spread of the flesh-eating livestock parasite. The latest cases involve a horse and a calf in Grant County, bringing the state's reported total to four since the pest returned to the United States this summer. Agriculture officials have established infested zones extending at least 12 miles around the affected locations. Livestock within those zones must be inspected and treated when necessary before being moved. 

New Mexico State Veterinarian Samantha Holeck says officials are increasing surveillance and working with state and federal partners to investigate the cases. Livestock owners should watch for wounds that fail to heal, foul-smelling discharge and unusual irritation. Officials emphasize that early detection and reporting are critical to preventing additional spread.
