USDA Confirms New screwworm Outbreak Threatens Livestock Industry Across Southern States
MIAMI, FLORIDA – The United States Department of Agriculture has officially confirmed a resurgence of the New World screwworm, a parasitic fly larvae infestation, posing an immediate and significant threat to livestock herds across multiple southern states. According to officials, the outbreak, first detected in a herd of cattle in Monroe County, Florida, on Tuesday, represents the first major U.S. infestation of the species since its eradication in 1966. The USDA Animal and Plant Health Inspection Service reports that the screwworm, scientifically known as Cochliomyia hominivorax, has already infected over 200 animals, prompting a federal emergency response and a mandatory quarantine zone spanning two counties. Agricultural experts warn that larvae burrow into open wounds of warm-blooded animals, causing severe tissue damage and potential fatalities if untreated. State veterinarians are now deploying sterile insect technique measures and travel restrictions to contain the spread, with agricultural losses projected to exceed 50 million dollars if the infestation expands. Federal authorities urge all livestock owners to immediately inspect animals for signs of infestation and report any suspicious lesions to local agricultural offices.
