What to know about the New World screwworm fly and its reappearance in the US
The New World screwworm fly, which had been eradicated in the U.S. since 1966, has reappeared in south Texas, threatening the $113 billion cattle industry. The infestation was detected in a 3-week-old calf near the U.S.-Mexico border, with the fly having previously spread in Mexico since late 2024. Federal officials confirmed this is the first case in Texas in over 50 years, using historical eradication methods like sterile male fly releases.
