Another case of New World screwworm was found in a Mexican cow south of the border. Despite that, USDA says it won’t limit cattle imports from Mexico. Reports say U.S. cattle supplies in recent months grew tight after Washington blocked Mexican livestock shipments into the U.S. in late November due to the screwworm presence. The World Organization for Animal Health says the disease was found in a cow located in the Mexican state of Tabasco.
