# Valley county judges meet to address New World screwworm threat

> New World screwworm has nearly 2,000 active cases in Mexico, about 200 of them near the Texas border, though there are no U.S. cases. Rio Grande Valley county judges and Texas officials held a press conference warning that the parasite will likely reach the U.S. and urging pet and livestock owners to treat wounds. USDA has begun building a sterile fly production facility at Moore Air Base near Edinburg.
