After sixty years of absence, a carnivorous parasite has returned to American soil — and it is feeding on the nation's cattle. The New World screwworm, once eradicated through one of agriculture's great cooperative triumphs, has been confirmed in Texas livestock, threatening not only individual animals but the economic foundation of the country's largest beef-producing state. What was once a hard-won victory over nature now stands as a reminder that eradication is not the same as permanence, and that the margins between containment and crisis can be measured in weeks.

US agricultural vulnerability creates dependency on USDA containment efforts; potential trade disruptions could shift livestock sourcing to South American suppliers; Mexico's cattle industry faces indirect threat, affecting US-Mexico agricultural trade balance.
1960s screwworm eradication required US-Mexico-Central America cooperation; reemergence tests current binational disease control frameworks and could strain agricultural trade relationships if containment fails.

Potential increase in beef prices due to reduced cattle supply and higher production costs from disease control measures. Consumers may face higher meat prices at retail if outbreak spreads and herd losses occur.
USDA likely to implement quarantine zones, mandatory livestock inspections, and movement restrictions. Potential emergency funding for affected ranchers, increased border biosecurity measures, and possible trade restrictions on cattle/beef exports. May trigger international trade negotiations.
