The USDA has confirmed the first New World screwworm case in U.S. wildlife, found in an elk harvested on a game ranch in Pecos County, Texas. The detection has led the USDA and Texas Parks and Wildlife Department to add wildlife surveillance in the area, while the Texas Animal Health Commission plans to modify a previously established infested zone. Officials are asking hunters and others to report suspicious signs, including maggots in wounds, foul-smelling or enlarging injuries, and animals that appear weak or distressed. The USDA says the parasite does not affect food safety, though it can affect meat production. The announcement gives no fees, forms, fixed deadlines, zone boundaries, or detailed enforcement requirements.
TLDR: The first confirmed U.S. wildlife case was found in a Texas elk, prompting added surveillance and a planned change to an existing infested zone. Officials urge immediate reporting of suspicious signs, while costs, zone boundaries, and other compliance details have not been provided.
The first confirmed New World screwworm case in U.S. wildlife has been found in an elk in Texas, the U.S. Department of Agriculture announced Wednesday. The animal was discovered on a game ranch in Pecos County and reported after a hunter harvested it, according to the USDA’s Animal and Plant Health Inspection Service. The finding has prompted additional wildlife surveillance in the area. Officials’ stated response is to monitor wildlife and change an existing infested zone after the detection. The announcement does not give a broader reason for those steps or describe a wider outbreak.
The USDA and Texas Parks and Wildlife Department are conducting added surveillance in the area. The agencies have not said how many animals will be checked, how long monitoring will continue, or what methods will be used. The finding joins a response already underway after an earlier detection in a Texas calf. But officials have not said that the elk and calf cases are connected.
The Texas Animal Health Commission will modify a previously established infested zone. The source does not provide the zone’s boundaries or the timing of the change. It also does not say what requirements will apply within the zone. No fees, forms, reporting deadlines, or specific enforcement measures are described. Those details remain unreported, rather than established parts of the response.
Officials have asked hunters to watch for visible signs of infection and report suspicious infestations immediately. Warning signs include maggots in wounds, foul-smelling injuries, open or enlarging wounds, and animals that appear weak or distressed. Infestations around an animal’s nose, mouth, ears, eyes, or genital areas are also listed. Hunters may be among the first people to see affected wildlife, especially when they are in the field. The instruction is to recognize possible signs and make a prompt report. The announcement does not describe a reporting phone number, website, or other process.
New World screwworm is a fly that lays eggs in open wounds or body openings of warm-blooded animals, including livestock and, in rare cases, humans. Once the eggs hatch, the larvae feed on living tissue, according to the Centers for Disease Control and Prevention. That life cycle helps explain why officials have urged people to watch for wounds and signs of distress. The available report does not identify a treatment plan or specify what happens after a suspected case is reported.
The wildlife detection follows a USDA confirmation in June of New World screwworm in a three-week-old Texas calf. The elk is the first reported case in U.S. wildlife, not the first detection of the parasite in the country. The calf and elk are separate confirmed cases in different animal settings, and the source does not establish a connection between them. It also does not report additional infected wildlife. The announcement provides no estimate of how many animals may have been exposed.
New World screwworm is typically found in South America and parts of the Caribbean. In recent years, it has spread north into Central America and Mexico. The USDA says the parasite does not affect food safety, though it can affect meat production. A human case was confirmed in the United States last year; the patient recovered, and officials found no evidence of further transmission. The source provides no new human case or evidence of transmission linked to the Texas elk.
The practical impact described so far is added local wildlife surveillance, a planned modification to the infested zone, and an immediate request for reports of suspicious signs. Hunters are specifically urged to monitor animals, while officials also ask anyone who notices possible infestation to report it. The announcement lists no costs, paperwork, fixed deadlines, or detailed compliance rules. It does not say whether the zone change will add restrictions for ranchers, hunters, or other people in the area. Its timing and boundaries have not been provided. For now, the next steps described are continued surveillance and the zone modification. Further requirements and oversight details remain unspecified.
