Staff Reports
The U.S. Department of Agriculture has confirmed a worrying development for ranchers and anyone who buys beef: New World screwworm has been found in a Texas calf for the first time in decades. This parasite eats living tissue, and one infected animal can mean big losses for a farm and a headache for government officials. The discovery puts a spotlight on federal action — and on whether that action was fast enough.
What officials say about the screwworm case
USDA officials confirmed the parasite in a three-week-old calf in Zavala County, Texas, marking the first U.S. case in many years. USDA leaders say they expected this and praise interagency cooperation across President Donald Trump’s entire administration. USDA Secretary Brooke Rollins called it the first confirmed Texas case since the 1960s and assured Americans that the commercial food supply remains safe. That may calm grocery-store shoppers, but it does little for a rancher with a sick animal and mounting costs.
What the USDA is doing: drugs, powders and sterile flies
The agency has not been idle. It has issued emergency authorizations for topical powders and injectable treatments to stop infestations in livestock. Officials have also restarted the proven eradication tool: releasing sterile male flies into affected areas so that wild females cannot produce viable eggs. The sterile-fly technique was how the U.S. beat this pest before. It works because female screw‑worms usually mate only once, and a sterile mate means no maggots.
Political reaction and real criticism
Sid Miller and others say the response was too slow
Not everyone is satisfied with the federal timeline. Texas Agriculture Commissioner Sid Miller bluntly criticized USDA strategy, saying the pest advanced through Mexico “in spite of” the agency’s plan and that officials relied on a partial solution that could take years to fully stop the spread. That’s a fair jab. When livestock, livelihoods, and grocery prices are at stake, “buying time” sounds like a public-relations line — not a plan that prevents economic pain for ranchers right now.
Why this matters and what should happen next
Screwworm outbreaks can kill animals, force culls, and raise beef costs for families already feeling price pressure. This is more than a local nuisance: it’s an agricultural vulnerability and a national security concern for a country that depends on a stable food supply. Federal agencies should move quickly to scale up sterile-fly production, speed distribution of approved treatments, and work with state and local partners on tighter biosecurity at border points. Ranchers deserve clear, fast action — and taxpayers deserve accountability for why a known threat was allowed to inch across the border before being met with full force.
The discovery is a wake-up call. We beat this pest before by using science and decisive action. We can — and must — do it again. If the federal response becomes all talk and not enough muscle, farmers and families will pay the price. That is a reality no press release can sugarcoat.
