This article describes the requirements of the Manual of Operations, Part 2 of the National Shellfish Sanitation Program, for conducting verification studies at depuration plants for molluscan shellfish. This article also describes the effect of the Hazard Analysis Critical Control Points (HACCPs) on such studies, and how to plan studies on new or existing plants. Methods are described for analyzing the various facets of the physical plant, such as sea water systems, tank construction, and other pertinent facilities. Of equal importance, methods are described for investigating and analyzing the various critical control points of the operation of the plant. Studies at a soft clam depuration plant are used as a model for this article. The most important items are (1) development of the zero-hour upper limit of fecal coliform bacteria in the clams, (2) attainment of final product criteria, (3) development of mid-cycle criteria, (4) flow rate of sea water, (5) tank loading, and (6) sea water parameters. A model is presented of the Scheduled Depuration Process, the operational specifications for the soft clam depuration plant.
