US EditionUS halts live cattle imports from Mexico to quell screwworm spread
- In May 2025, U.S. Authorities halted imports of live cattle from Mexico to help prevent the spread of the New World screwworm along the border.
- The suspension followed detection of the flesh-burrowing screwworm parasite, which the U.S. Eradicated nearly 60 years ago but has recently advanced north from Central and South America.
- The USDA works with Mexico, which has activated emergency measures since late 2023 and fulfilled all U.S. Requests to contain the screwworm infestation spreading as far north as Oaxaca and Veracruz.
- USDA Secretary Brooke Rollins said on social media that the pest's last U.S. Invasion took 30 years for the livestock industry to recover, calling protection of animals a national security issue.
- The import halt will be reviewed monthly until containment shows progress, while Mexican officials and President Claudia Sheinbaum continue opposing the decision as unfair but seek resolution.
