Less than 70 miles stands between the latest New World screwworm (NWS) detection and the U.S.-Mexico border, according to a statement by the USDA late Sunday, Sept. 21. “Hours ago, Mexico’s National Service of Agro-Alimentary Health, Safety, and Quality confirmed a new case of NWS in Sabinas Hidalgo, located in the state of Nuevo León,” the statement read. This is the farthest north NWS has been detected since the beginning of the outbreak. Before this detection, the northernmost case was reported in July from Veracruz — about 370 miles farther south. We have given Mexico every opportunity and every resource necessary to counter NWS since announcing the NWS Bold Plan in June 2025.
