That's an interesting question!

Snails are not a very common food in the United States, but are often eaten in Europe, Africa and elsewhere.

Land snails that are eaten in restaurants and purchased in shops come from farms (snail farming is called 'heliculture'). The most popular farmed land snail species are Helix pomatia and Helix aspersa. Both species are native to Europe, but are now widespread because people have brought them across the world.
