Mussels can be affected by environmental contaminants, as non-dioxin-like polychlorinated biphenyls (NDL-PCBs), polycyclic aromatic hydrocarbons (PAHs) and cadmium (Cd). Moreover, mussels may concentrate human enteric viruses, like noroviruses (NoVGI/GII), astrovirus (AsV) and rotavirus (RV). Herein, to establish a relationship between environmental and viral contamination, with the aim to ensure human food safety, both chemical and microbiological analysis were carried out in mussels Mytilus galloprovincialis, farmed in Campania region (Italy). Chemical analysis revealed ranges below the European maximum limits, and were: ∑6 NDL-PCBs (28, 52, 101, 138, 153, 180) 0.579-16.857 ng g wet weight (ww); BaP LOQ (<0.2 µg kg)- 2.9 µg kg ww, and ∑4 PAHs (BaA, CHR, BbFA, BaP) 0.7-23.7 µg kg ww; Cd LOQ (<0.005 mg kg)- 0.078 mg kg ww. In addition, mussels exhibited a prevalence of NoVGI (18%), NoVGII (43%), AsV (40%), RV (30%) and the presence of more than one viruses resulted in about 35%. Overall, a simultaneous contamination, both chemical and viral, was found in 62% of samples. Interestingly, virus-positive mussels showed levels of chemicals higher than negative ones.
贻贝可能受到环境污染物的影响，如非二恶英类多氯联苯（NDL-PCBs）、多环芳烃（PAHs）和镉（Cd）。此外，贻贝可能会浓缩人类肠道病毒，如诺如病毒（NoVGI/GII）、星状病毒（AsV）和轮状病毒（RV）。在此，为了建立环境和病毒污染之间的关系，旨在确保人类食品安全，对意大利坎帕尼亚地区养殖的贻贝 Mytilus galloprovincialis 进行了化学和微生物分析。化学分析显示，浓度均低于欧洲最大限量值，具体为：∑6 NDL-PCBs（28、52、101、138、153、180）为 0.579-16.857ng/g 湿重（ww）；BaP 定量下限（<0.2μg/kg）-2.9μg/kg ww，∑4 PAHs（BaA、CHR、BbFA、BaP）为 0.7-23.7μg/kg ww；Cd 定量下限（<0.005mg/kg）-0.078mg/kg ww。此外，贻贝的 NoVGI（18%）、NoVGII（43%）、AsV（40%）、RV（30%）检出率较高，且有 35%的样本同时存在多种病毒。总体而言，62%的样本存在化学和病毒的同时污染。有趣的是，病毒阳性贻贝的化学物质水平高于阴性贻贝。
