A microbiological survey of 287 (fresh) seafood products from Puget Sound retail markets was conducted over a period of 1 year. The microbiological quality of fresh seafood was high, with only 2.1 % of the samples exceeding the maximum limit for acceptability as suggested by the International Commission on Microbiological Specifications for Foods (ICMSF). The overall microbiological data of positive units given as arithmetic means were: coliforms MPN/g, 199; Escherichia coli MPN/g, 21; coagulase-positive Staphylococcus aureus MPN/g, 66; enterococci/g, 9121; Clostridium perfringens /g, 18; Bacillus cereus /g, 100; and Vibrio parahaemolyticus MPN/g, 3.7. The standard plate count means 1.0 × 10 to 2.5 × 10 colony-forming units (CFU)/g, giving a mean value of 2.0 × 10 CFU/g. The percentages of seafood samples positive for pathogens were S. aureus , 37.6; Yersinia enterocolitica , 3.8; V. parahaemolyticus , 2.8; C. perfringens , 2.4; and B. cereus , 0.7. Vibrio cholerae , Clostridium botulinum , Salmonella and Shigella species were not isolated.
在一年时间里，对普吉特海湾零售市场的287种（新鲜）海产品进行了微生物学调查。新鲜海产品的微生物质量较高，只有2.1%的样本超过了食品微生物规范国际委员会（ICMSF）建议的可接受最大限量。以算术平均值给出的阳性单位的总体微生物学数据如下：大肠菌群MPN/g，199；大肠杆菌MPN/g，21；凝固酶阳性金黄色葡萄球菌MPN/g，66；肠球菌/g，9121；产气荚膜梭菌/g，18；蜡样芽孢杆菌/g，100；副溶血性弧菌MPN/g，3.7。标准平板计数平均值为1.0×10至2.5×10菌落形成单位（CFU）/g，平均值为2.0×10 CFU/g。海产品样本中病原体呈阳性的百分比分别为：金黄色葡萄球菌，37.6%；小肠结肠炎耶尔森菌，3.8%；副溶血性弧菌，2.8%；产气荚膜梭菌，2.4%；蜡样芽孢杆菌，0.7%。未分离出霍乱弧菌、肉毒梭菌、沙门氏菌和志贺氏菌属。
