Threat from Parasitic Screwworm Hits Texas Cattle Industry

The New World screwworm, a harmful fly that preys on warm-blooded animals, has been detected in Texas. The U.S. Department of Agriculture confirmed a case in a young calf, sparking concerns for the cattle industry.

Agriculture Secretary Brooke Rollins reported the incident involving a three-week-old calf in La Pryor, which is located approximately 50 miles from the Mexico border. To contain the situation, Texas State Veterinarian Bud Dinges has implemented a 12-mile quarantine zone. This measure prevents the movement of any warm-blooded animals, including pets, without prior inspection.

Rollins stated that no additional cases of the fly have been reported in the country. While the larvae pose a threat to livestock, they do not contaminate food. Proper treatment can lead to the recovery of affected animals, as Rollins reassures.

The discovery of the screwworm comes at a time when U.S. cattle numbers are at their lowest in decades, driving beef prices to record levels. An outbreak could further reduce cattle supplies and push prices even higher. This is an unfolding story, with more updates expected.
