Molluscan Shellfish Program

The Molluscan Shellfish Program is the regulatory agency for the oyster harvesting waters along Louisiana Gulf Coast. The harvesting areas are set forth by the Louisiana Sanitary Code and the National Shellfish Sanitation Program (NSSP). The NSSP is the federal/state cooperative program recognized by the U.S. Food and Drug Administration (USFDA) and the Interstate Shellfish Sanitation Conference (ISSC) for the sanitary control of shellfish produced and sold for human consumption. All oyster related facilities must follow Louisiana Administrative CodeTitle 51 Part IX and NSSP guidelines.
