Includes bibliographical references. "Bivalve molluscs are unique as food items in this hemisphere, as they are often eaten raw or partially cooked, with the entire animal being consumed, including the gastrointestinal tract and its contents. Because of their mode of feeding, bivalves can accumulate many substances which occur in their growing waters.
