🚨 NEW WORLD SCREWWORM CONFIRMED IN TEXAS CALF 🚨
Dearest Readers,
The news many ranchers, veterinarians, and livestock producers have been dreading has officially arrived.
The USDA has confirmed the presence of New World Screwworm (NWS) in a calf in South Texas, marking the first confirmed case in Texas since 1966 and the first known domestic livestock infestation in the United States in decades.
According to reports, the infestation was found in a 3-week-old calf in Zavala County near La Pryor, Texas, not far from the Mexican border. Authorities have established a quarantine area and begun increased surveillance, trapping, and response efforts.
For those unfamiliar with screwworms, this is not your average fly problem.
The adult fly lays eggs in wounds, navels, cuts, branding sites, castration sites, tick bites, and other openings. When the eggs hatch, the larvae don't feed on dead tissue.
They feed on living flesh.
As the larvae burrow deeper into the wound, the infestation grows larger, more painful, and can become fatal if not treated. The parasite can affect cattle, horses, sheep, goats, wildlife, pets, and in rare cases even humans.
This is the kind of issue that can impact entire industries.
Before eradication efforts in the last century, screwworm infestations cost livestock producers millions of dollars and caused devastating losses. Texas officials have warned that a widespread outbreak could have enormous economic consequences for the state's livestock industry.
Now the questions turn to prevention.
• Are you checking wounds daily?
• Are you monitoring navels on newborn calves and foals?
• Have you talked to your veterinarian about what to watch for?
• If you haul livestock, are you paying attention to unusual wounds that won't heal?
The USDA and Texas officials are actively responding, but ranchers and horse owners are often the first line of defense.
For our cattle producers, horse owners, veterinarians, wildlife folks, and ranch families:
What are you hearing on the ground?
Are you changing anything in your management practices because of the screwworm threat?
Always Observing,
The Bettys ☕️
