I knew a young man, his parents had citrus, and olives groves. He went out and collected snails, and then feed them a special diet for a certain amount of time, I am thinking cornmeal,but could be wrong. Then sold them to a market supply. So maybe they are in the Semi, because they have been processed for humans to eat. Sounds good to me. My Youngest Daughter and I samples Es cargo while at Pismo Beach. To me taste like Garlic and Butter.....
