The California Department of Public Health’s Shellfish Program is managed by the Environmental Management Branch (EMB) and the Food and Drug Branch (FDB) within the Center for Environmental Health. EMB manages the state’s Marine Biotoxin Monitoring Program and also regulates the commercial molluscan shellfish aquaculture industry for all pre-harvest elements of the National Shellfish Sanitation Program (NSSP). FDB is responsible for all post-harvest elements of the NSSP and has additional responsibilities, including the monitoring for marine toxins in other commercial fisheries (for example, crab, anchovy) in collaboration with the California Department of Fish and Wildlife and the regulation of manufacturers and distributors of seafood products.
