Mexico’s National Service of Agro-Alimentary Health, Safety, and Quality (SENASICA) detected the flesh-eating parasite on September 21 in Sabinas Hidalgo, Nuevo León. The city of Sabinas Hidalgo sits along a major highway from Monterrey, Nuevo León, to Laredo, Texas—one of the busiest trade routes in the world. Also look for screwworm larvae (maggots) and eggs in or around body openings, such as the nose, ears, and genitalia or the navel of newborn animals. According to SENASICA, the affected animal had been recently moved to a certified feedlot in Nuevo León from a region in southern Mexico with active NWS cases. “USDA is analyzing all new information related to the recent case in Nuevo León and will pursue all options to release sterile flies in this region as necessary,” the agency wrote.1References
