Texas Takes Action to Prevent Screwworm Fly Infestation: All You Need to Know

Texas on Guard Against New World Screwworm Threat

In an urgent move to protect the state's livestock and wildlife, Texas Governor Greg Abbott declared a statewide disaster on January 29, 2026. This declaration aims to combat the potential threat posed by the New World screwworm, a parasite advancing north from Mexico. Though the screwworm is not yet present in Texas, its proximity poses a grave risk to the animal agriculture sector and, by extension, the state's food supply.

The Implications of the Screwworm Infestation

The New World screwworm fly is notorious for its destructive larvae, which can burrow into the flesh of living animals, causing serious and often fatal damage. According to the U.S. Department of Agriculture, if the screwworm were to infest livestock, the consequences could ripple throughout the food supply chain, threatening national security as well. The devastation could extend beyond livestock to include pets, wildlife, and in rare cases, humans.

Proactive Measures Taken by the State

Governor Abbott’s disaster declaration empowers the Texas New World Screwworm Response Team to utilize all available state resources for prevention and eradication of this pest. This team is a collaborative effort between the Texas Parks and Wildlife Department and the Texas Animal Health Commission.
In a significant stride toward safeguarding Texas agriculture, the state has also partnered with the USDA to establish a $750 million facility in Edinburg dedicated to producing sterile screwworms. This facility aims to mitigate the potential impacts of any future infestation by managing the screwworm population effectively.

Historical Context and Background

The United States has faced threats from the New World screwworm before. For decades, outbreaks resulted in the loss of livestock and heavy economic burdens on farmers. Understanding the historical context underscores the importance of current preventive measures. Past infestations have taught authorities the necessity of immediate and decisive action.

What This Means for Texas Ranchers

The livestock industry is a cornerstone of Texas's economy, contributing significantly to job creation and rural livelihoods. The proactive stance taken by state officials signals a commitment to protecting this essential sector. For ranchers, the threat of screwworms symbolizes the broader challenges they face, including disease outbreaks and environmental factors. Their focus is not just on maintaining health but also ensuring economic stability.

Looking Toward the Future: Prevention Is Key

The New World screwworm serves as a reminder of the interconnectedness of environmental management, agriculture, and public health. With potential future trends in mind, Texas officials emphasize ongoing monitoring and rapid response initiatives. Technology and collaboration, particularly with federal agencies, will be indispensable in maintaining this vigilance.

Conclusion: Protecting Livestock and Wildlife

The recent disaster declaration by Governor Abbott is a crucial step in safeguarding Texas's agricultural integrity against potential threats. As Texas ramps up its preventive measures, it stands as a testament to the importance of readiness in the face of emerging pests and diseases. The protection of livestock ultimately contributes to the safety of the nation’s food supply.

In light of the ongoing issues regarding agricultural biosecurity and environmental health, it’s clear that proactive measures like these are more essential than ever. Stay informed and engaged as we track the progress of this response and its broader implications for Texas's farming community.
