New World screwworm threat continues as USDA, Texas tries to stop it

The New World screwworm, a parasitic fly once eradicated in the United States during the 1960s, reemerged near the Texas border. Recent detections within 25 miles of the border have prompted the USDA to intensify surveillance and control efforts. Texas authorities are collaborating with federal agencies to deploy targeted insecticides and monitor livestock movements. The resurgence raises concerns about potential spread to neighboring states and the impact on the livestock industry. Ongoing research focuses on rapid detection methods and genetic analysis to prevent further establishment of the screwworm population in the years and the industry will benefit.
