First US Case of New World Screwworm Parasite Raises Alarms on Border Health and Biosecurity

By Economics Desk | August 25, 2025

A traveler returning from El Salvador is the first confirmed U.S. case of the New World screwworm parasite amid ongoing outbreaks abroad, spotlighting vulnerabilities in border health security and agricultural protections long fought for by American ranchers.

On August 4, the Centers for Disease Control and Prevention (CDC) confirmed a troubling development: a person who recently traveled to El Salvador was diagnosed with New World screwworm, marking the first U.S. case tied explicitly to travel from a country experiencing an active outbreak. While this parasitic infection remains rare in humans, its arrival inside our borders underscores serious gaps in national biosecurity protocols that demand immediate attention.

New World screwworm is not your everyday illness. This parasitic fly targets open wounds or body orifices—eyes, ears, nose, or mouth—laying eggs that hatch into larvae feeding on living tissue. Though primarily a devastating threat to livestock, particularly cattle, this parasite carries risks that ripple far beyond isolated infections. For decades, American cattle ranchers endured significant losses until aggressive eradication efforts largely eliminated the screwworm within the United States by the 1970s.

What Does This Mean for America’s Borders and Agriculture?

The recent case is more than a medical rarity—it is a glaring warning sign about border vulnerabilities and the challenges posed by uncontrolled pests migrating northward through Central America and Mexico. As outbreaks persist abroad, Washington’s failure to fortify our defenses against biological threats jeopardizes our cherished national sovereignty and economic prosperity.

The CDC’s collaboration with Maryland health officials and coordination with the U.S. Department of Agriculture highlight ongoing efforts to contain this spread—but reactive measures will never be enough if we continue lacking robust border screening and enforcement protocols. How long can America afford to invite these bio-threats through porous borders under failed policies that prioritize globalist agendas over national security?

Protecting Our Farmers Means Protecting America

The impact on ranchers cannot be overstated. The screwworm infestation threatens livestock health, farm incomes, and ultimately food supplies for all Americans—especially those who depend on affordable domestic beef and dairy products amid rising inflation. President Trump’s administration championed reclaiming control over borders while strengthening agricultural protections; these principles remain essential today.

We must hold accountable those in Washington who compromise our biosecurity through negligence or misplaced priorities. For families already burdened by economic uncertainty, allowing foreign parasites to gain foothold on American soil is an avoidable disaster.

This incident demands more than quiet acknowledgment; it requires action grounded in common sense conservatism: secure borders, protect farmers’ livelihoods, and uphold America’s hard-won sovereignty against invasive threats masquerading as mere health concerns.
