US has reclosed its southern border after a flesh-eating parasite is seen further north in Mexico
UNITED STATES, JUL 11 – The U.S. halted livestock imports after detecting New World screwworm 160 miles closer to the border, with $30 million invested to breed sterile flies to contain the parasite.
- The United States has once again halted livestock shipments across its southern boundary due to the northward spread of the flesh-eating New World screwworm fly in Mexico.
- This closure comes in response to a fly infestation detected 185 miles to the northeast of Mexico City, which is roughly 160 miles farther north than previously identified cases, leading to increased monitoring and action.
- USDA Secretary Brooke Rollins revealed plans to invest close to $30 million in establishing additional facilities for breeding and releasing sterile male flies, with the goal of opening a fly production plant in southern Mexico by July 2026.
- President Claudia Sheinbaum said Mexican authorities follow all protocols and called the border closure decision "totally exaggerated," while USDA pledged vigilance to protect the beef industry.
- The closure reflects concerns that the parasite, largely eradicated in the 1970s by sterile fly releases, could cause major economic losses if it reaches Texas, prompting calls to approve anti-parasite treatments.
