The USDA released sterile flies at a ranch near Uvalde, Texas, as part of efforts to contain New World screwworm. The agency reported seven active U.S. cases—six in Texas and one in New Mexico—and said it had released 142 million sterile flies in Texas since February.
Sterile-fly releases are intended to curb a disease threat to cattle and limit potential disruption to herd health and marketing; the article does not report a direct price effect.
