摘要：The sanitary survey is aimed at classifying and monitoring the production areas of live bivalve molluscs (LBM) and it is performed using standards that are provided by the Centre for Environment, Fisheries and Aquaculture Science’s Guide to Good Practice In this study, data from the sanitary survey carried out by the Asl5 Spezzino on the production areas of the gulf of La Spezia during the period 20152017 were analysed The number and type of the analysis performed both on the total sampling and on the individual target species, as well as the number and type of found noncompliance (assessed on both mandatory parameters and on parameters fixed by the local monitoring plan) were considered Data were also compared with those from the sanitary survey 20122014 Appropriate statistic tests were used to evaluate data from E coli and Norovirus monitoring Overall, 4306 analysis were performed, especially on the species M galloprovincialis (89%) and they were mostly focused on to the search of biological agents 160 NC were detected Most of the NC concerns the Norovirus’s positivity (9375%) in M galloprovincialis and C gigas A correlation between the levels of E coli and rainfall/ seasonality (higher levels in the colder months) was proved, especially in the sampling points located in the inner part of the dam and in the Portovenere Bay Class B was reconfirmed for M galloprovincialis, the production areas of C gigas were reclassified as A and those of V verrucosa were definitively closed The sanitary survey was therefore confirmed as a useful tool for reclassification and for monitoring LBM production areas.
