'It's a relief': How 100% inspections regulate Mexican cattle exports to US
Mexican veterinarians inspected every animal before the first cattle crossed into the United States, restoring a trade route after the screwworm suspension.
On August 24, Mexico resumed cattle exports to the United States after a screwworm-related suspension, with the first shipment crossing from Agua Prieta, Sonora, into Douglas, Arizona.
Federal officials suspended trade to prevent the spread of the New World screwworm, a parasitic fly that lays eggs in warm-blooded animals and causes significant tissue damage to livestock.
USDA Undersecretary Dudley Hoskins stated compliance with strict protocols is essential, with inspectors utilizing electronic tags and visual screenings to ensure no animals carry the parasite before crossing.
Unión Ganadera Regional de Sonora official Sergio Villalobos García emphasized following these standards is essential. Officials warn any new screwworm detection will trigger immediate border closures.
Mexico continues releasing sterile flies to eradicate the parasite as part of a long-term strategy. Continued vigilance remains necessary to protect the livestock industry from future outbreaks.
