U.S. suspends cattle imports from Mexico to stop spread of harmful New World Screwworm.

The U.S. has suspended live cattle, horse, and bison imports from Mexico due to the spread of New World Screwworm (NWS), a pest that can seriously harm animals and wildlife. The suspension, announced by Agriculture Secretary Brooke Rollins, will be reviewed monthly and is aimed at preventing the northward spread of NWS, detected as far north as Oaxaca, Mexico. Mexico disagrees with the measure.
