(NAFB.com) – With no active cases of New World Screwworm (NWS) reported in the United States, the USDA is working to prevent its spread from Central America. Successful Farming reports U.S. Secretary of Agriculture Brooke Rollins outlined the Department of Agriculture’s plan to prevent the spread of NWS to the U.S., including a partnership with the government of Mexico. NWS is a fly that lays eggs in the wounds of living animals and its larvae burrow and feed on healthy flesh, causing illness or death. The insect usually infects livestock and is typically found in South and Central America, but one case was detected in a human this summer who had returned from travel to El Salvador. “President Trump’s America First agenda means our (agricultural) community deserves unwavering support in the face of critical threats like this one,” she said. “As the situation evolves, we will continue our efforts to keep vulnerable livestock ranchers and the rest of America safe. The U.S. has defeated the NWS before, and we will do it again.
