The USDA has confirmed a case of the flesh-eating New World screwworm in a Texas calf, marking its return after being eradicated in 1966. To contain the outbreak, officials have established a 20-kilometer quarantine zone and are releasing millions of sterile flies to crash the population.

The affected animal, an 8-month-old cow, had recently been transported to a certified feedlot in Nuevo León from southern Mexico, where active screwworm cases are present.
