State and regional animal health officials have confirmed the Rio Grande Valley’s first reported New World screwworm case in Starr County, a development that puts renewed attention on livestock monitoring across South Texas.
New World screwworm is a parasitic fly whose larvae can infest wounds in warm-blooded animals. Officials typically urge ranchers, veterinarians and animal owners to watch for suspicious wounds, separate affected animals and report concerns quickly so cases can be contained.
The confirmation comes as border and agricultural agencies continue monitoring animal health risks in South Texas. Livestock owners should follow guidance from animal health authorities and contact a veterinarian if they notice signs of infestation or unusual wounds.
