More screwworm cases identified in New Mexico

2 new screwworm cases in New Mexico

GRANT COUNTY, N.M. – New Mexico officials confirmed two more New World screwworm cases in Grant County, expanding response efforts and adding restrictions in two infested zones.

State and federal officials said they are expanding surveillance and fly-trapping around the affected locations to look for more cases and to determine whether the pest spread beyond the affected animals.

The new cases involve one horse and one calf. Officials said they set a minimum 12.4-mile radius infested zone around each affected animal’s location.

The northernmost zones are now combined into one larger zone, leaving two separate infested zones in New Mexico. Within those zones, animals must be inspected and treated if needed before they move within or out of the area.

“We are working closely with our state and federal partners to investigate these cases, increase surveillance and monitor for additional infestations,” said State Veterinarian Dr. Samantha Holeck with the New Mexico Livestock Board.

“We appreciate the continued cooperation of livestock producers, veterinarians and animal owners as we respond to these additional cases,” said New Mexico Secretary of Agriculture Jeff Witte.

Officials urged animal owners to watch for wounds that do not heal, worsening injuries, maggots in wounds, foul-smelling discharge or unusual irritation around an injury. They said anyone who suspects New World screwworm should contact the New Mexico Livestock Board right away and avoid moving the affected animal.
