The New World screwworm fly is threatening the $113 billion U.S. cattle industry for the first time in more than half a century, as officials race to eradicate a flesh-eating parasite not seen in Texas since 1966.
Two new cases were found in a calf and a dog hundreds of miles apart, the U.S. Department of Agriculture announced Monday. That brings the state's total to four.
Texas is home to $17 billion worth of the nation's cattle, making it the industry's No. 1 state.
