Hunters and ranchers enlisted in battle against spread of flesh-eating parasite
Officials have enlisted hunters and ranchers to help track New World screwworm after it was detected in an elk in Pecos County, western Texas. The finding marks the first confirmed case in U.S. wildlife during the current outbreak and has prompted increased surveillance.
The USDA and Texas wildlife authorities are asking people outdoors to report wounds containing maggots, foul smells or animals that appear weak or distressed. The parasite was eliminated from the United States decades ago but has moved north through Central America and Mexico; previous cases in Texas included a calf, horse and dog. Livestock imports from Mexico were paused for more than a year, contributing to pressure on cattle supplies and beef prices, though the USDA says screwworm does not affect food safety.
In short
- Screwworm was found in a Texas elk.
- It is the first confirmed U.S. wildlife case in this outbreak.
- Hunters and ranchers are being asked to report signs of infection.
Steelman: both sides, in good faith
The strongest fair case each way — we don't pick a winner.
The case for
Enlisting hunters and ranchers could extend surveillance across remote areas more quickly than officials can cover alone, helping detect infections early and limit harm to wildlife and livestock. Their local knowledge and regular time outdoors may make them well placed to spot warning signs, while reporting suspected cases supports a shared effort to contain a parasite with significant agricultural consequences.
The case against
The approach asks members of the public to identify signs that may be difficult to distinguish from other conditions, potentially producing false alarms or diverting attention from confirmed cases. It also places more monitoring responsibility on people whose primary roles are hunting or ranching, while the wider response—including sustained official surveillance and decisions about livestock imports—remains a matter for government agencies.
