The need for sanitary control of molluscan shellfish resulted from the use of rivers, streams, and the sea for the disposal of sewage. Sewage discharged into the sea is rapidly and enormously diluted, but many shellfish beds of commercial importance are situated within long inlets or estuaries where dilution is less effective. In such places molluscs, by virture of their mode of feeding, can become polluted to an extent which make them unsafe to eat uncooked.
