Authorities in the United States confirm the New World screwworm—an infestation of larvae in wounds—has reappeared in Texas. Reports state an initial case in a calf in Texas prompted an aggressive federal and state response aimed at stopping further spread. The West Australian and CBS News describe confirmation of a second case near the Mexico border, adding to growing concern about a potential expansion beyond the original area. Other outlets, including the Los Angeles Times, Stuff.co.nz, MedPage Today and the Guardian, report additional confirmed cases, with at least one found outside the main Texas cluster. The Guardian also reports that Texas’s governor issues a disaster declaration as agencies work to slow the spread, including measures such as releasing sterile flies. Across sources, officials warn the parasite can kill livestock by damaging living tissue and that its return could pose risk to the cattle industry. Several outlets note the episode is the first threat in decades and that authorities monitor whether the insect could reach other cattle-producing states, including California.
