Ideal growing areas for oysters were identified, where relaying sites were established, which could be able to reduce E. coli counts from 24,000 MPN/ 100 g to ā¤ 20 MPN/ 100 g after 2 weeks of relaying, making the raw oyster safe for human consumption. Comprehensive data on the sanitary quality of the oyster growing areas in Capiz, and Aklan were generated. This data shall serve as impetus for the establishment of the Philippine National Shellfish Sanitation Program whose primary task shall include the continual monitoring of the sanitary quality of oysters and their culture environments.
