The U.S. will run much the same playbook as it did starting in the 1950s: mass-produce sterile male screwworms and release them into the wild to stop the pests from reproducing.

The US Department of Agriculture says New World screwworm has been detected in a Texas calf.

Agriculture Secretary Brooke Rollins confirmed the first case of a flesh-eating screwworm fly in the United States in 60 years, threatening livestock.
