Mexico Increases Cattle Controls Following Screwworm Case Near U.S. Border

What's Happening?

Mexico has implemented emergency controls after a new case of New World screwworm was detected in cattle in Nuevo Leon, a northern border state close to the U.S. This marks the nearest case to the U.S. border since the outbreak began last year. The affected animal originated from Veracruz, prompting the U.S. to suspend imports of live Mexican cattle. The New World screwworm, a larva of the Cochliomyia hominivorax fly, poses a threat to warm-blooded animals, including humans. Mexico has reported over 500 active cases in cattle across its southern states. The import suspension has created challenges for Mexico, which is already dealing with economic pressures from President Trump's tariff threats. Mexico's Agriculture Secretary, Julio Berdegué, stated that the country is managing the isolated case in Nuevo Leon under measures agreed with the U.S. in August.

Why It's Important?

The suspension of cattle imports from Mexico could have significant economic repercussions, potentially leading to losses of up to $400 million for Mexico's ranching industry if the ban persists. This situation underscores the vulnerability of cross-border agricultural trade to health-related disruptions. For the U.S., maintaining strict import controls is crucial to protect its livestock industry and food supply from the screwworm, which can have devastating effects on animal health. The incident highlights the importance of international cooperation in managing agricultural pests and diseases, as well as the economic interdependence between the U.S. and Mexico in the livestock sector.

What's Next?

The U.S. Agriculture Secretary, Brooke Rollins, has emphasized that the U.S. will continue to enforce the import suspension on Mexican cattle, bison, and horses to safeguard its borders. The situation may prompt further diplomatic discussions between the two countries to address the outbreak and potentially lift the ban. Mexico will likely intensify its efforts to control the screwworm outbreak to mitigate economic losses and restore trade relations. The outcome of these efforts will be closely monitored by stakeholders in both countries, including ranchers and government officials.
