Shellfish Program
clams and a clam digger The mission of the NHDES Shellfish Program is to examine the sanitary quality of the state’s tidal waters, in order to ensure that the molluscan shellfish in those waters meet standards for consumption by those who enjoy harvesting these public resources. To this end, the NHDES Shellfish Program 1) evaluates the sanitary quality of all coastal shellfish growing waters in the state, and ensures that these evaluations are kept current through periodic re-evaluations; 2) identifies pollution sources and other factors that render the state’s shellfish resources unfit for human consumption; 3) works with local officials, other state agencies, environmental organizations, and members of the public to eliminate pollution sources, especially those that limit opportunities for shellfish harvesting; and 4) informs and educates the public about the sanitary quality of the state’s tidal waters and shellfish resources, as well as potential health risks associated with shellfish. more...
