NM shifts to regional screwworm map as cases grow

New Mexico animal health officials have shifted to regional New World screwworm-infested zone maps because detections have recently expanded in the southern part of the state. Expanding the infested zone will strengthen surveillance and help prevent the pest from spreading, according to a news release. This designation will not affect most residents’ dayto- day activities, but it will help animal owners understand when additional inspections or movement requirements may apply to livestock, horses, pets, and other animals. The new zone map encompasses all of Doña Ana, Grant, Hidalgo, Luna and Otero counties, and portions of Catron, Chaves and Sierra counties. An infested zone, extending at least 12.4 miles around an affected location, is established to support surveillance and prevent the pest from spreading, the release stated. Cases were confirmed in five counties over the weekend, including newly affected areas in Catron County and in northern Otero County.
