Risk Management Knowledges about Oysters for Raw Consumption and Norovirus.

This study used questionnaires to evaluate knowledge levels of risk management of raw-consumption of oysters and of norovirus as health hazards among monitors signed up for Food Safety Commission of Japan (FSCJ) having work experiences in food fields. The mean scores of monitors on norovirus knowledge were relatively high (79%), but on oyster raw-consumption were low (64%). Scores varied depending on occupational experiences; highest among administrative officials, high among researchers in food companies, and low among medical workers and educators. The higher scores with more practical experiences for risk management of oyster raw-consumption and norovirus were observed among the monitors. These monitors were expected better to recognize the risks, wheres only few monitors among the opinion-leaders replied correctly to all the questions. These results suggest the need of improvement on the management system for oyster raw-consumption, from the current complicated to the more precise and reinforced for consumers. To efficiently manage the risk associated with the consumption of raw oysters, the government should provide more relevant information of risk management to persons having interest, particularly influencers, in order to disseminate information and to improve knowledge among cooks and consumers.
