USDA Confirms Flesh-Eating Screwworm in Texas Calf, Initiates Eradication Measures
The U.S. Department of Agriculture (USDA) has confirmed the presence of a flesh-eating New World screwworm in a three-week-old calf located in Zavala County, Texas. The USDA is taking immediate action to eradicate the parasitic fly by establishing a 12-mile 'infested zone' around the detection site, implementing quarantines, increasing traps for screwworms along the border, and setting up an Incident Command Team with the Texas Animal Health Commission. The screwworm, typically found in South America and parts of the Caribbean, has been detected farther north in Central America and Mexico over the last three years. The USDA has invested heavily in tools to eliminate the screwworm, which can infest livestock and other warm-blooded animals, including humans in rare cases.
