Outbreaks of human gastroenteritis have been linked to the consumption of contaminated domestic and imported seafood. This study investigated the microbiological quality of seafood obtained from retail stores on the Eastern Shore of Maryland. A total of 440 samples of domestic and imported frozen shrimp, catfish and tilapia samples were analyzed for aerobic plate count (APC), total coliforms, and seafood-borne-pathogens (, ). The prevalence of APC, coliforms and positive samples was 100%, 43% and 9.3%, respectively. Approximately 3.2%, 1.4%, 28.9% and 3.6% of the samples were positive for and , respectively. The MPN/g ranges were 150-1100 MPN/g for vibrios, 10-1100 MPN/g for and 93-460 MPN/g for in seafood, respectively. Comparing bacterial prevalence by type or source of seafood, the only significant difference identified was -positive imported tilapia (33.3%) versus domestic tilapia (19.4%). The quantitative data on pathogen levels in the present study provide additional information for quantitative risk assessment not available in previous surveys. The findings of this study suggest the association of potential food safety hazards with domestic and imported seafood and warrant further large-scale studies and risk assessment.
人类肠胃炎的爆发与食用受污染的国产和进口海鲜有关。本研究调查了从马里兰州东海岸零售店获取的海鲜的微生物质量。共对440份国产和进口冷冻虾、鲶鱼和罗非鱼样本进行了需氧平板计数（APC）、总大肠菌群和食源性病原体（ ）分析。APC、大肠菌群和阳性样本的患病率分别为100%、43%和9.3%。分别约有3.2%、1.4%、28.9%和3.6%的样本对 和 呈阳性。海鲜中弧菌的MPN/g范围为150 - 1100 MPN/g， 的MPN/g范围为10 - 1100 MPN/g， 的MPN/g范围为93 - 460 MPN/g。按海鲜类型或来源比较细菌患病率，唯一显著差异是进口罗非鱼（33.3%）的 阳性率高于国产罗非鱼（19.4%）。本研究中病原体水平的定量数据为以往调查中没有的定量风险评估提供了额外信息。本研究结果表明国产和进口海鲜存在潜在食品安全危害，值得进一步开展大规模研究和风险评估。
