- 6 decades of eradication: The New World screwworm was eradicated from the U.S. for 60 years before its resurgence in 2026.
- 15 confirmed cases: By late June 2026, at least 15 cases were detected across Texas and New Mexico.
- $1.8 billion annual cost: A major outbreak could cost the Texas economy over $1.8 billion per year.
Experts would likely conclude that the USDA's appointment of a private-sector leader with deep industry expertise signals a critical, innovative approach to combating the resurgent screwworm threat through advanced technology and rapid response strategies.
USDA Taps Industry Veteran to Lead Tech Defense Against Resurging Screwworm
SAN ANTONIO, TX – June 22, 2026 – In a move signaling a high-stakes battle against a resurging biological threat, the U.S. Department of Agriculture has appointed a seasoned private-sector leader to fortify the nation's defenses. John Bellinger, a board member of Certified Group and co-founder of food safety testing giant Food Safety Net Services (FSNS), has been named Senior Advisor for New World Screwworm Preparedness by Secretary of Agriculture Brooke L. Rollins.
The appointment is not a routine bureaucratic shuffle; it is a direct response to a crisis that was, until recently, a closed chapter in American history. After being eradicated from the country for six decades, the New World screwworm—a parasitic fly whose larvae consume the living flesh of warm-blooded animals—has been detected again on U.S. soil. With confirmed cases in Texas and New Mexico, Bellinger's appointment underscores a national strategy to blend government authority with private-sector agility to protect the country's multi-billion-dollar livestock industry and its already fragile protein supply chain.
A Nightmare Resurfaces
For ranchers and veterinarians, the New World screwworm (Cochliomyia hominivorax) is the stuff of horror stories. Unlike other flies that lay eggs in decaying matter, the female screwworm fly seeks out open wounds on living animals—even one as small as a tick bite. The larvae hatch and burrow into living tissue, creating a gruesome, ever-enlarging wound that causes immense pain, secondary infections, and often, death. Before its eradication in 1966, the pest cost the U.S. livestock industry hundreds of millions of dollars annually.
The historic victory against the screwworm was a landmark achievement of American science, accomplished through the ingenious Sterile Insect Technique (SIT), which involves releasing vast quantities of sterilized male flies to breed wild females out of existence. For decades, a biological barrier maintained at the Darien Gap in Panama has protected North America. But starting in 2023, the pest began a northward march, and on June 3, 2026, the USDA confirmed the first U.S. case in a cow in Zavala County, Texas. By late June, at least 15 cases had been confirmed in livestock and a pet dog across two states.
While officials are quick to note this is an animal health crisis, not a direct food safety issue—the pest does not infect meat—the business implications are staggering. It is a crisis of food production that threatens to destabilize an entire economic sector.
The High-Stakes Economic Equation
The re-emergence of the screwworm could not come at a worse time for the U.S. beef industry. Producers are already grappling with the smallest national cattle herd in decades, a situation that has caused beef prices to soar 57% since 2020. An uncontained screwworm outbreak would be catastrophic, introducing widespread animal losses and further constricting supply.
A 2024 USDA economic report paints a stark picture, estimating that a major outbreak could cost the Texas economy alone more than $1.8 billion per year. The impact ripples far beyond direct livestock losses. In response to the initial detections, southern U.S. ports were temporarily closed to livestock trade, choking off the vital flow of feeder cattle from Mexico and straining supply chains for feedyards in the Southern Plains.
These disruptions create a domino effect, increasing competition for a dwindling supply of domestic cattle and ultimately exerting more upward pressure on consumer beef prices. The economic stability of countless ranches, rural communities, and associated businesses hangs in the balance, making the effectiveness of the national response a critical economic priority.
Bridging Public Need with Private Expertise
This is the complex landscape John Bellinger now enters. His appointment is a clear signal that the USDA is looking beyond traditional government response models and tapping into the specialized knowledge of the private sector. Bellinger’s career has been spent at the intersection of animal science, laboratory diagnostics, and food systems management.
As co-founder of FSNS, he built a company centered on the very disciplines now essential to combating the screwworm: rapid, accurate laboratory testing and robust safety systems. This background provides invaluable insight into scaling up the diagnostic capabilities needed to track and contain the pest.
“John has spent his career applying practical science and industry leadership to some of the beef industry's most important challenges,” said David Morgan, CEO of Certified Group, the parent company of FSNS. “His appointment reflects the trust he has earned across the industry and the broader food safety community.”
That trust is crucial. Bellinger understands the protein industry from a 360-degree perspective, from the realities of cattle production and the complexities of global meat exports to the microscopic view of a laboratory technician. Morgan added, “His strategic, global protein experience and steady leadership will be invaluable as USDA works to protect livestock, producers, and the beef supply chain.”
Mobilizing a Modern Defense
Bellinger's advisory role is a key component of a broader, aggressive “One Health” response being mobilized by the USDA. This strategy involves intensive surveillance, establishing quarantine zones, and managing animal movement out of infested areas. Critically, the agency is investing heavily in ramping up the production of sterile flies, aiming to deploy 500 million per week—the same volume that won the war 60 years ago.
But this isn't just about reprising old victories. Bellinger is specifically tasked with helping the USDA evaluate and advance the technologies of preparedness. His mission is to accelerate the development and deployment of next-generation tools for testing, detection, and response. This could involve everything from faster, field-deployable diagnostic tests that don’t require a full lab, to data modeling that can better predict the pest's spread based on weather and animal movement, to evaluating new treatments and ensuring their safe use in the food supply.
In appointing Bellinger, the USDA is not just hiring an advisor; it is integrating a mindset of private-sector innovation into a national security operation. The fight against the New World screwworm will be won or lost based on surveillance, science, and speed. By embedding an industry expert focused on technological advancement, the agency is betting that the best way to defeat a resurgent 20th-century pest is with a 21st-century strategy.
