This undated photo provided by United States Department of Agriculture (USDA) shows a person using two hands to hold a single snail from an air cargo shipment of 67 live snails that arrived at Los Angeles International Airport on July 1, 2014. Officials said that the 35 pounds of snails arrived from Nigeria along with paperwork stating they were for human consumption. Officials say the snails were intercepted and they were subsequently identified after a sample was sent to U.S. Department of Agriculture specialists in Washington, D.C. (AP Photo/USDA, Greg Bartman)
