In this study, we investigated the occurrence, seasonal distribution, and molecular characterization of pathogenic vibrios in Mediterranean mussels () and grooved carpet shells () from two harvesting areas of Sardinia (Italy). Samples collected before and after depuration were submitted for qualitative and quantitative determination of spp. spp.

The aim of the present study was to investigate the genetic variability of Vibrio parahaemolyticus strains isolated from naturally contaminated Mediterranean mussels (Mytilus galloprovincialis) and Grooved carpet shells (Ruditapes decussatus) from three harvesting areas of Sardinia (Italy) using a combination of different typing methods: traditional phenotypic systems and molecular techniques. Ninety-nine putative V. parahaemolyticus strains isolated from shellfish collected before and after purification were included in the study.

The aim of the present study was to investigate the effect of short purification cycles on the safety of naturally contaminated Mytilus galloprovincialis from harvesting areas of the Gulf of Olbia (Sardinia, Italy). Samples from ten batches of mussels were collected before, during and after purification treatment at two purification centres (A-B). All the samples were analysed for Escherichia coli and Salmonella spp according to Council Regulation (EC) 2285/2015.

cheese is a salted variety of traditionally made in Sardinia (Italy) from the whey remaining after the production of protected designation of origin or other sheep milk cheeses. cheese is very critical for the possible growth of pathogenic and spoilage microorganisms. Sporadic cases of listeriosis associated with cheese have been reported over recent years.

Ready-to-eat (RTE) food is characterised by a long shelf-life at refrigerated temperature and can be consumed as such, without any treatment. The aim of the work was to evaluate the presence of spp. and in RTEs collected from refrigerated vending machines placed in hospital environment and accessible to the hospitalised patients.

In a 3-year study (2008 to 2011) to estimate the prevalence and the contamination sources of Listeria monocytogenes in pork meat in Sardinia, Italy, 211 samples were collected from five Sardinian swine slaughterhouses: 171 samples from slaughtered pigs and 40 from the slaughterhouse environment. Fifty L. monocytogenes isolates were characterized by PCR-based serotyping, presence of virulence-associated genes, and pulsed-field gel electrophoresis restriction analysis.
