Fifth Case of New World Screwworm Confirmed in the US

A fifth case of New World screwworm has been confirmed, FOX 7 Austin reports. The New World screwworm is a parasitic fly whose larvae infest living tissue in warm-blooded animals. Previous cases had already prompted concern among livestock and wildlife officials. The confirmation of a fifth case suggests the parasite may be spreading or persisting in the region. Authorities typically respond with quarantine measures and surveillance to contain outbreaks. The screwworm was previously eradicated from the U.S. but has reappeared in recent years. Officials are likely monitoring livestock and wildlife for additional signs of infestation. The situation raises concerns for the agricultural sector and animal health across affected areas.
