US ranchers warn of screwworm threat as Mexico relents under USDA pressure

The threat of a flesh-eating fly infestation advancing through Mexico has put U.S. ranchers on high alert. Buck Wehrbein, the president of the National Cattlemen’s Beef Association (NCBA), has raised concerns about the potential devastation this parasitic fly, known as the New World screwworm, could wreak on American cattle herds. Despite efforts by Agriculture Secretary Brooke Rollins to combat the outbreak, the crisis is far from over, and time is running out before a U.S. ultimatum expires.

Wehrbein emphasized the severity of the situation, highlighting the gruesome nature of the screwworm larvae burrowing into the flesh of livestock and causing fatal wounds. The eradication of these pests from the U.S. in the 1960s was a significant achievement, and Wehrbein is adamant about preventing a resurgence of this threat.

The screwworm infestation was first detected in southern Mexico late last year, prompting the temporary halt of Mexican cattle imports to the U.S. U.S. authorities have been working diligently to contain the outbreak, relying on a sterile insect technique (SIT) program to keep screwworm populations in check. However, bureaucratic interference by Mexican authorities has hindered these efforts, leading to delays in critical fly-release missions and allowing the pest to spread further.

In a letter dated April 26, Secretary Rollins issued a deadline for Mexico to address these issues by April 30, threatening to halt the import of live cattle, bison, and equine if the situation is not resolved. This ultimatum has underscored the seriousness with which U.S. officials view the threat to the country’s food supply.

Wehrbein expressed frustration at the bureaucratic obstacles that have impeded progress in combating the flesh-eating fly infestation. However, he welcomed Secretary Rollins’ announcement that Mexico has agreed to allow U.S. sterile fly planes to land, calling it a significant victory for American ranchers. While this development marks a turning point in the fight against the screwworm, Wehrbein emphasized that the threat is not yet eradicated.

Looking ahead, Wehrbein stressed the need for the U.S. to reassess its reliance on outside partners for biosecurity measures. He suggested that establishing a domestic supply of sterile flies could help mitigate the risk of future outbreaks and reduce dependence on other countries for cooperation in times of crisis.

As the leader of the NCBA, Wehrbein remains committed to protecting the cattle industry and ensuring the safety and well-being of American livestock. The recent challenges posed by the flesh-eating fly infestation serve as a stark reminder of the importance of vigilance, cooperation, and leadership in safeguarding the nation’s food supply.

In conclusion, the efforts to combat the New World screwworm infestation highlight the resilience and determination of U.S. ranchers and officials in the face of agricultural threats. By working together and implementing proactive measures, the cattle industry can continue to thrive and provide essential resources to the country and the world.
