U.S. Opens New Facility to Combat New World Screwworm Threat

Introduction of the New Facility
The United States has inaugurated its first center for dispersing sterile New World screwworm flies in decades, located in Edinburg, Texas. This facility aims to prevent the northward spread of the flesh-eating parasite that poses a significant threat to American livestock. U.S. Secretary of Agriculture Brooke Rollins and Texas Governor Greg Abbott participated in the ribbon-cutting ceremony on February 9, 2026. The center will enable the U.S. to release millions of sterile male screwworm flies, which are bred in Mexico and Panama, to mate with wild females, thereby preventing the hatching of larvae that can infest livestock and other animals.
Background and Context
Historically, a similar program successfully eradicated the New World screwworm from the U.S. by the early 1970s. However, there have been recent concerns due to a limited outbreak in the Florida Keys in 2017 and a case involving a horse imported from Argentina. Following the eradication efforts, the U.S. closed its fly factories, relying on a single facility in Panama for sterile fly production, which currently produces approximately 117 million flies weekly. The new facility in Texas is expected to significantly increase production capacity to 300 million flies per week.
Key Developments and Investments
The U.S. Department of Agriculture (USDA) is investing $750 million to construct a new fly breeding factory, expected to be completed by the end of 2027. Additionally, the USDA is allocating $21 million to convert a fruit fly breeding facility in southern Mexico into one for breeding screwworm flies. This strategic investment aims to bolster efforts to combat the pest and protect the U.S. cattle industry, which has faced challenges due to infestations affecting the Mexican cattle sector.
Official Statements & Responses
Secretary Rollins emphasized the collaborative effort among federal, state, and local entities, stating, “It's a real testament to the all hands on deck... the fact that we do not have the pest in our country yet.” Governor Abbott noted the necessity of a “short-term, gap-filling solution” to address the immediate threat posed by the screwworms.
Criticism & Opposition
Despite the optimism surrounding the new facility, some experts express concern over the potential ecological impacts of introducing sterile flies into the environment. Critics argue that while the program aims to protect livestock, it may inadvertently affect local ecosystems and wildlife.
What's Next
The USDA has announced plans to offer up to $100 million in grants for projects aimed at enhancing fly breeding techniques, developing new traps and lures, and creating treatments for infestations. These initiatives are part of a broader strategy to ensure the continued protection of American livestock from the New World screwworm.
