The resurgence of the screwworm parasite is posing a significant threat to cattle in Texas, with U.S. Agriculture Secretary Brooke Rollins warning that the pest could become a billion-dollar international problem if not contained.
Rollins emphasized that ranchers must remain vigilant, closely monitor their herds and local wildlife, and promptly treat any infestations to prevent the parasite from spreading further.
The screwworm, a flesh-eating larvae that infests open wounds in livestock, has been detected in several Texas counties, prompting urgent calls for action. The situation has sparked a political blame game, with state and federal officials trading accusations over who is responsible for the delayed response.
Critics argue that budget cuts and reduced surveillance programs have allowed the parasite to gain a foothold, while others point to cross-border movement of animals from Mexico as a contributing factor.
Rollins, speaking at a press conference in Austin, stressed that containment is achievable through coordinated efforts between ranchers, veterinarians, and government agencies. She urged livestock owners to inspect animals daily and report any suspicious wounds or maggot infestations immediately.
The U.S. Department of Agriculture has deployed additional inspectors and is working with state authorities to set up quarantine zones in affected areas.
The screwworm outbreak has already caused economic losses for some ranchers, who have had to cull infected animals and face restrictions on livestock movement. The Texas Animal Health Commission has issued guidelines for treatment and prevention, including the use of approved insecticides and sterile insect technique releases.
However, the political fallout continues, with lawmakers demanding a full investigation into the response timeline and funding allocations.
As the situation develops, ranchers are being advised to stay informed through local extension offices and the USDA's Animal and Plant Health Inspection Service. The coming weeks will be critical in determining whether the outbreak can be contained or if it will escalate into a larger crisis affecting the entire livestock industry.
