Abstract: 漁獲から加工場に至る水産物の衛生管理・品質向上を図るうえで,漁港で利用されている海水の実態の把握が重要であり,港内海水の水質,一般生菌数および食中毒菌の生菌数を調査した。調査した羅臼・標津・由比・博多の各漁港の港内海水の水質項目のうち,SS と COD 値は総じて水産用水基準値を上回る結果となった。漁港内海水から大腸菌群・大腸菌が検出され,由比・博多では Vibrio parahaemolyticus が分離された。市場の殺菌海水あるいは海洋深層水からは大腸菌は分離されず,洗浄による除菌効果も認められた。
To control the hygienic conditions of fishery products from catching to landing and processing, both qualitative and quantitative bacterial observations at fishing ports must be considered. Four fishing ports, Shibetsu and Rausu in Hokkaido, Yui in Shizuoka prefecture, and Hakata in Fukuoka prefecture, were selected and the distribution of coliform bacteria and human pathogenic vibrio species were studied at these sites. Coliforms and Escherichia coli were observed from all four fishing ports, while Vibrio parahaemolyticus was observed from Yui and Hakata fishing ports. The number of V. parahaemolyticus in the surface seawater varied seasonally from <1.8 to 240 MPN/100 mL. E. coli and human pathogenic vibrio species were not observed from electrolyzed, chlorine disinfected or deep seawater used at these four fishing ports for hygiene control. The disinfected seawater or deep seawater for hygiene control was effective for washing off the bacteria from floors and equipment at the fishing markets.
