KRWG Public Media • • nation
Key Points:
- New Mexico has confirmed its second case of New World screwworm in a horse in Grant County, prompting state and federal officials to expand surveillance and fly-trapping efforts in the area.
- A 12.4-mile radius infested zone has been established around the affected animal, where animals must be inspected and treated before moving to prevent the spread of the pest.
- A broader surveillance zone will support ongoing monitoring, with increased animal health checks and fly-trapping to detect additional cases beyond the infested zone.
- Routine animal movement is generally allowed unless a higher-risk situation is identified, in which case movement may be delayed or adjusted in coordination with livestock officials.
- Officials urge livestock producers, pet owners, and the public to remain vigilant for signs of screwworm infestation, such as non-healing wounds or maggots, and to report suspicious cases immediately to help contain the pest.
