Political blame game follows as screwworm parasite threatens cattle in Texas

Key Points:

• U.S. Agriculture Secretary Brooke Rollins observed the release of sterile flies to combat the New World screwworm, a parasite threatening the nation's cattle industry, and visited a Texas ranch where recent cases were detected.
• Rollins blamed the Biden administration for the parasite's return to the U.S. after six decades, citing unauthorized livestock movement, while Democrats attribute the resurgence to prior USDA budget cuts under the Trump administration.
• The USDA plans to spend over $1 billion on a large-scale sterile fly production facility and other measures to contain the outbreak, aiming to protect the cattle industry and prevent a major increase in beef prices.
• Screwworms, which thrive in warm, humid climates and lay eggs in animal wounds, have caused significant issues in Mexico and have led to import restrictions by the U.S. and Canada; climate change is facilitating their northward spread.
• Scientists remain uncertain about the exact cause of the screwworms' reemergence but emphasize the importance of international cooperation and ramping up sterile fly releases to control the population and drive the pests back south.
