Despite the United States’ work to control the New World screwworm, weak governmental participation in Central America allowed the insect to spread north out of Panama. This has been coupled with a lack of timely action by officials in Mexico and now the U.S. cattle herd, other livestock, wildlife, pets and humans are at risk again. Consequently, the USDA has closed the U.S. southern border to shipments of cattle, bison and horses despite potential economic harm to farmers and ranchers.
