New World Screwworm Confirmed in Texas Affecting Livestock

The U.S. Department of Agriculture (USDA) confirmed the presence of the New World screwworm (Cochliomyia hominivorax) in a three-week-old calf in Zavala County, Texas. A press statement revealed larvae were found in the calf's umbilical area. In response, the USDA is establishing a 20 km infested zone and implementing quarantines and movement controls. This pest is known to affect livestock, potentially leading to significant economic losses in agriculture, which makes swift containment measures essential for protecting the sector.
