Mexico Confirms Case Of NWS Closer To U.S. Border

Late last night, Mexico’s National Service of Agro-Alimentary Health, Safety and Quality confirmed a new case of New World screwworm (NWS) in the state of Nuevo León, which is less than 70 miles from the U.S. border. This now is the northernmost detection of NWS during this outbreak and the one most threatening to the U.S. livestock industry.

Preliminary reports from Mexico indicate the affected animal—an 8-month-old cow—recently had been moved to a certified feedlot in Nuevo León from a region in southern Mexico with known active NWS cases. The potential link to animal movement underscores the non-negotiable need for the country to fully implement and comply with the U.S.–Mexico Joint Action Plan for NWS in Mexico. Currently, U.S. ports remain closed to imports of cattle, bison and horses from Mexico.
