The U.S. Department of Agriculture (USDA) has confirmed the first case of New World screwworm detected in a dog in the United States, along with a new case in a Texas goat, as federal and state officials race to contain the flesh-eating parasite’s spread near the Texas-New Mexico border.

Local Impact

According to a June report from USDA’s Animal and Plant Health Inspection Service, the dog case was initially reported in Andrews County, Texas, but was later reclassified as the first confirmed case in New Mexico after investigators determined the animal actually lives at a household in Lea County, New Mexico. However, the veterinarian who reported the case is based in Texas.

USDA officials said the case appears isolated, but because the dog’s travel history and possible exposure to the parasite remain unknown, the agency has expanded their investigation into the report. That includes inspecting other animals in the dog’s household and stepping up outreach to residents in the surrounding area to see if there are any other active cases.

Guidance for Pet Owners

Dr. Shalsee Vigeant, DVM and Medical Director at VEG ER, said pet owners shouldn’t wait for an obvious wound before checking on their animals. “Warning signs include licking, scratching, or bothering a small sore on the skin, as well as any swelling or discharge near a site,” she said. “In case the wound is not visible, pet owners should also look out for signs of a decreased appetite or feeling of general malaise, accompanied by an area of swelling on the pet’s skin. If pet owners notice any of these symptoms, have it checked out ASAP.”

USDA is urging residents in affected areas to inspect their animals daily for draining or enlarging wounds, maggots or egg masses, signs of discomfort or irritability, and lesions around body openings like the ears, nose, genital area or umbilicus. Anyone who suspects an infestation is asked to contact a veterinarian, state animal health official, or USDA directly through the agency’s national reporting page.
