New World Screwworm Case Identified in a Working Horse in Texas
A flesh-eating parasite case found in a horse in southern Texas has prompted authorities working to control the outbreak into action.
A New World screwworm case has been detected in a working horse located in Presidio County, southern Texas. This development marks the first horse case in the country for health authorities trying to halt the flesh-eating parasite outbreak.
Detected on the Horse's Leg
The United States Equestrian Federation announced on Thursday that the pest was discovered on the hind leg of a ranch horse in Presidio County.
Warning to Owners for Daily Checks
The foundation warned horse owners to inspect their animals daily for wounds, foul odors, or maggots.
This screwworm, which is a blowfly larva, can settle inside open wounds and lead to infection.
Restrictions on Animal Movements
The Texas Animal Health Commission restricted the movement of warm-blooded animals out of infested areas in parts of Presidio and Jeff Davis counties to prevent new infestations.
Spread Trajectory of the Outbreak
The screwworm, which was eradicated decades ago, was re-detected in June on a calf in Zavala County near the US-Mexico border, and the parasite has spread throughout Mexico.
According to United States Department of Agriculture data, all 49 cases recorded this year occurred in the state of Texas, with the exception of one found in a dog in New Mexico.
Threatening Ranchers
The re-emergence of the parasite, which can cause severe injuries or death in animals, has heightened concerns that it holds the potential for financial devastation for Texas ranchers.
Texas Governor Greg Abbott issued a disaster declaration in June to mobilize state resources to combat the surging screwworm presence.
