The New World screwworm, a parasitic fly known for infesting livestock, has resurfaced in the United States, specifically detected in a three-week-old calf in Texas. This marks a significant concern as the screwworm was eradicated from the U.S. 60 years ago following extensive control efforts. The pest has been migrating north from South America, where it remains prevalent, raising alarms about its potential impact on the livestock industry. Caleb Hubbard, an entomologist from New Mexico State University, emphasized that the screwworm could severely damage cattle farming, potentially leading to increased beef prices. Although the pest poses threats to wildlife and pets, federal and state officials assert that the risk to the general public is currently low. Agriculture Secretary Brooke Rollins highlighted the importance of collaboration and adherence to animal treatment guidelines to prevent the establishment of the screwworm in the U.S. Officials are actively working to contain the situation in Texas, hoping to mitigate the effects of this unwelcome return.
