Knowledge and Practice About Food Poisoning by Fish and Shellfish in Hiroshima Region Inhabitants
Fish and shellfish
Recently, contamination of Hiroshima Bay by sewage has been getting worse, and cultured oysters are being infected by noro virus (small round structured virus) originating in excrement. However, it seems that there are a few people who have accurate knowledge about food poisoning by oysters and noro virus. In this study, we investigated the knowledge of food hygiene and practice of food poisoning prevention that the inhabitants had in Hiroshima region. By this questionnaire, generation of 30's had the highest knowledge. On the other hand, about practice to prevent food poisoning, 50's was good, and young generation of 20-30 years old was inferior. In addition, most of them did not understand danger of taking the fish and shellfish which were not heated. And they did not know kinds, properties and characteristics of pathogenic microor-ganisms. Furthermore, they hardly know properties and characteristics of oysters and noro virus. Most of them did not wash hands with soap before cooking. And most of them did not distinguish cutting boards by purposes of use. A recent study shows that sixty-six percent of the people heat oysters before they eat. However, as for the person who was conscious of noro virus in oysters, there was only half. Oysters are cultivated in large quantities in Hiroshima Bay, but consciousness about oysters and noro virus which inhabitants of Hiroshima have is low.
