Flesh-Eating Parasite Found in Texas Elk Prompts Urgent Action
The discovery of a flesh-eating parasite, known as the New World screwworm, in an elk in western Texas has raised concerns among officials. This has led to a call for action from hunters and ranchers to contain its spread.
The U.S. Department of Agriculture (USDA) confirmed the presence of the screwworm in an elk found on a game ranch in Pecos County. A hunter reported the animal after it was killed. In response, the USDA, in collaboration with the Texas Parks and Wildlife Department (TPWD), is increasing wildlife surveillance. The Texas Animal Health Commission is also planning to adjust an already existing infested zone.
“Hunters and others who spend time outdoors near infested areas play a crucial role in detecting affected wildlife. Their observations are valuable in surveillance and response efforts,” stated the USDA.
The discovery in Pecos County marks the first confirmed case in U.S. wildlife during the current outbreak. The parasite has also been identified in cattle in Texas and New Mexico. Officials urge hunters and ranchers to remain vigilant for signs of the parasite as it spreads northward.
The USDA cautioned hunters to watch for visible maggots in wounds or body openings, expanding wounds, foul smells, and animals that appear weak or distressed. Particular attention should be given to infection signs around the nose, mouth, ears, eyes, or genital areas.
The TPWD advised hunters to examine harvested animals before field dressing or moving them. Symptoms such as irritated behavior, lack of appetite, head shaking, the smell of decaying flesh, or unusual solitary behavior should raise alarms.
New World screwworm was eradicated in the U.S. decades ago, but it has been advancing north through Central America and Mexico. Measures such as halting livestock imports from Mexico were previously implemented to prevent its spread, causing a prolonged shortage in cattle supply and contributing to high beef prices. The phased reopening of imports began in August.
Reports earlier in the year confirmed the parasite in a Texas calf and later in other animals, including a horse and a dog. The partnership between TPWD biologists, local hunters, and landowners has been pivotal in swiftly identifying and confirming new detections, emphasized Alan Cain, Texas wildlife division director.
New Mexico officials recently reported screwworm in a beef cow, leading to the establishment of an infested zone around the case. Animals within the zone must be inspected and treated, if necessary, before movement. Although New World screwworm poses significant risks to animal health and meat production, it does not impact food safety, according to the USDA.
The National Cattlemen’s Beef Association announced it was coordinating with state partners to tackle the screwworm issue. Federal eradication efforts involve heightened fly surveillance, cattle treatments, and sterile-fly releases.
