U.S. Takes Action Against New World Screwworm Outbreak

Federal authorities have implemented measures to address the first detection of New World screwworm cases in the U.S. in ten years. The Centers for Disease Control and Prevention (CDC) activated an emergency response to investigate the outbreak and prepare for potential human exposure.

Agriculture Secretary Brooke Rollins emphasized the importance of the CDC’s involvement in deploying federal resources. Concurrently, the Food and Drug Administration authorized the emergency use of a generic over-the-counter tablet, nitenpyram, to treat New World screwworm in animals. This marks the first generic animal drug authorized for parasite treatment.

Seven cases have so far been confirmed in Texas and New Mexico in cattle, a goat, and a dog. The screwworm’s larvae feed on the living tissue of warm-blooded animals, entering through open wounds, causing severe suffering if untreated. The screwworm was previously eradicated in the U.S. in the 1960s but reappeared in Florida between 2016 and 2017. It remains endemic in South America and the Caribbean. Although human infections are rare, no U.S. cases have been reported in this outbreak.
