Yes, with farm raised or cultured shellfish the source of the clams is highly traceable and can be assured to be from a safe growing area. Shellfish farmers have a licensed site to work from, one which has been identified to be in a growing area meeting all water quality standards for harvest of shellfish. The harvest and handling of harvested shellfish are subject to numerous regulatory requirements by location and are federally outlined in the National Shellfish Sanitation Program (NSSP) Guide for the Control of Molluscan Shellfish through the FDA and Interstate Shellfish Sanitation Conference (ISSC). If you are interested in even more detail, individual farms can even tell you exactly how they were grown!
