# 128 confirmed New World Screwworm cases across Southwestern U.S. states

> The USDA is reporting 128 confirmed New World screwworm cases in Texas, New Mexico, and Arizona. Texas Animal Health Commission officials say confirmed cases have risen over recent weeks as moderate temperatures and moisture create favorable conditions for the fly. Infested zones with animal movement controls, inspections, treatments and movement permits are being used to contain spread.
