June 4 (UPI) -- Agriculture Secretary Brooke Rollins confirmed the first case of a flesh-eating screwworm fly in the United States in 60 years.
Rollins posted on social media Wednesday that the Cochliomyia hominivorax, also known as the New World screwworm fly, has been discovered in Zavala County, Texas. Its presence threatens an already weak cattle herd in the United States.
As expected, @USDA_APHIS confirmed the detection of a New World Screwworm (NWS) fly in a 3 week old bovine in Zavala County, Texas. @USDA and Texas Animal Health @TAHC officials are taking immediate action to contain and eradicate NWS from the area.
