Scientists Link

Scientists say organized-crime cattle trafficking fuels the screwworm resurgence, linking it to deforestation and other animal diseases in Central America.
The U.S. Department of Agriculture confirmed a screwworm case in a Texas calf and warned Texas outbreak could cost $1.8 billion.
Researchers say fly rides smuggled cattle and dogs through Darien Gap, a crime-run route.
Fidel Gutíerrez, Mexican smallholder, lost a cow and spent $1,000 treating calves amid poor animal-control.

Blindspot

Center coverage emphasized the USDA’s quarantine, sterile-male-fly release and import bans, while Left coverage gave less weight to these containment actions.
Center coverage highlighted the agency’s assessment that the outbreak poses low risk to the U.S. food supply, a point absent from Left coverage.

History

Historical Context

In 1954 Edward Knipling’s sterile-insect trials on Curaçao proved the technique, leading to the New World screwworm’s eradication from the United States by 1966 after releases of over 94 billion sterile flies (1962-1975). The species reappeared in Mexico in 2024 and in Zavala County, Texas in June 2026, prompting the USDA to reinstate a 12-mile quarantine and massive sterile-male releases.
