The U.S. Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the first case of New World screwworm (NWS) in New Mexico, detected in a dog residing in Lea County.
The case was initially reported June 8 in Andrews County, Texas, where the veterinarian who identified the infestation is located. Because the dog lives in a household in Lea County, New Mexico, USDA reclassified the case as the first detected in that state.
USDA believes the case is isolated. However, because the dog's recent travel and exposure history remain unknown, the agency and state partners have begun inspecting additional animals in the dog's home and increased outreach in the area while continuing to investigate the animal's movement history.
"This situation is evolving, and we expect new information to emerge as our investigation continues," said Dudley Hoskins, under secretary for marketing and regulatory programs. "USDA is committed to sharing what we learn quickly, accurately and transparently so animal owners and local communities have the information they need to stay vigilant. We are working closely with our partners in New Mexico, Texas and across the region to ensure we identify, contain and respond to any potential cases as swiftly as possible."
NWS poses a serious threat to livestock, pets, wildlife and, in rare cases, people. The larvae feed on living tissue and can cause severe wounds, animal suffering and significant economic harm if not detected and treated quickly.
APHIS and New Mexico state officials are implementing actions outlined in the NWS Response Playbook, including continuing the epidemiological investigation, sampling additional animals in the household, fly trapping, preparing for the release of sterile insects if needed, and conducting outreach in the area to encourage reporting of additional suspect cases.
Additional case confirmed in Texas
USDA's National Veterinary Services Laboratories also confirmed a case of NWS in a goat in Gillespie County, Texas. USDA and the Texas Animal Health Commission are gathering additional details about the case, establishing surveillance and testing in the area, and sharing outreach materials and information.
