2nd New World screwworm case confirmed in New Mexico

(KVIA) -- New Mexico animal health officials confirmed a second New World screwworm case in the state. It was found in a horse in Grant County, which is west of Deming.

State and federal officials expanded surveillance and fly-trapping around the location to find any additional cases and determine whether the pest spread beyond the horse.

The New Mexico Department of Agriculture said a 12.4 mile radius is under establishment around the horse's location. Within the zone, animals have to be inspected and, if needed, treated before moving.

An additional surveillance zone will support monitoring and early detection.

NMDA said signs of New World screwworm may include:

• Wounds that fail to heal or worsen over time
• Presence of maggots in a wound
• Foul-smelling or draining wounds
• Animals persistently licking, biting or aggravating a wound
• Irritation, discomfort or unusual behavior around an injury site

Anyone who observes a suspicious wound or suspects NWS should immediately contact the New Mexico Livestock Board and avoid moving the affected animal.

Producers should also keep an eye on open wounds, keep them clean and cover them. Infested animals should be treated under a veterinarian's direction.

As of Friday, the U.S. Department of Agriculture recorded 50 animal cases of NWS. Three of those are active, including the horse in Grant County. The other two are a horse and dog in Texas.
