European Legislation has fixed microbiological, chemical and biotoxicological limits for shellfish but no limits for viruses. In the present study we report the results of an investigation on Salmonella spp., Escherichia coli, Hepatitis A virus (HAV) and Norovirus (NoV) contamination in 59 bivalve shellfish collected during the years 2011-2012 in Southern Italy. All the samples of Mytilus galloprovincialis and of Solen marginatus were negative for HAV whereas 6.8% of them were positive for Norovirus GI (NoVGI) and 11.9% positive for Norovirus GII (NoVGII). Samples were also negative for Salmonella spp., while 16 of them (27%) were positive for E. coli. No correlation was found between E. coli and NoV contamination in bivalve molluscs. Moreover, the Competent Authorities are advised to take into serious consideration additional measures for the legislation in force in order to guarantee the consumer's health.
欧洲立法规定了贝类的微生物、化学和生物毒理学限量，但未对病毒设定限量。在本研究中，我们报告了2011 - 2012年期间在意大利南部采集的59份双壳贝类中沙门氏菌属、大肠杆菌、甲型肝炎病毒（HAV）和诺如病毒（NoV）污染情况的调查结果。所有的加利福尼亚贻贝和缘管浒苔样本的甲型肝炎病毒检测均为阴性，而其中6.8%的样本诺如病毒GI（NoVGI）呈阳性，11.9%的样本诺如病毒GII（NoVGII）呈阳性。沙门氏菌属样本检测也为阴性，而其中16份样本（27%）的大肠杆菌检测呈阳性。在双壳贝类中未发现大肠杆菌与诺如病毒污染之间存在相关性。此外，建议主管当局认真考虑对现行立法采取额外措施，以保障消费者健康。
