Molluscan shellfish are filter-feeding animals that can accumulate bacteria and virusespresent in the growing waters to levels significantly higher than the waters that they are grownin. In addition, they are commonly consumed raw or partially cooked, representing a significantpublic health risk when shellfish are grown in waters potentially impacted by contaminationsources. The proper classification of shellfish growing waters is critical to providing safeshellfish to consumers. The project is intended to improve the capability and capacity of the Virginia ShellfishSanitation program by: 1) Enhancing the data collection and Geographic Information System(GIS) integration of inspections conducted as a part of shellfish growing area sanitary surveys;2) Development of an integrated GIS model for quick and accurate assessment of the impactsof point source discharges and spills to shellfish growing waters; and 3) Improvement in thecapability of the Virginia Department of Health to assess the potential health risks associatedwith harmful algal blooms (HAB). The deliverables described in the research strategy will bedeveloped using Virginia data. The data infrastructure and modeling capability, an outcome ofthis project, will be easily utilized by any state shellfish program for performing similar tasks asrequired under the National Shellfish Sanitation Program. These improvements will addressmany of the United States Food and Drug Administration's goals to provide modern andinnovative approaches in risk assessment, inspection and investigation activities conducted bystate regulatory food programs.

The proper classification of shellfish growing waters is critical to providing safe shellfish to consumers. This project proposes to improve shellfish growing area classification by: modernizing the inspection and investigation capability of field staff performing sanitary survey inspections; developing rapid tools to assess and investigate the potential impact of point source discharges and spills to shellfish growing areas;and providing rapid methods to investigate and determine the potential toxicity of algal blooms that occur in shellfish growing waters.
