Contamination of food by Coagulase Positive Staphylococci (CPS) may derive from several sources such as raw materials, operator or the environment. This last source can transfer a high CPS concentration to foods, especially if cleaning and disinfection practices are not properly applied In this study, the presence of CPS in dairy environments was evaluated and S. aureus strains were genotypically and phenotypically characterized according to the resistance to biocide molecules and the ability in enterotoxin production. All isolates were susceptible to the action of biocides tested. More than a third also showed multidrug resistance to antibiotics and the presence of at least one gene encoding staphylococcal enterotoxins. Finally, analysis of pulsed field gel electrophoresis (PFCE) restriction profiles revealea the presence of multiple different pulsotypes in the same working environment. Source

Listeria monocytogenes is a ubiquitous bacterium, widely distributed in the environment; morover, its ability to survive at low temperatures and form protective biofilms makes it colonise and persist in food processing plants. Epidemiological data provided by EFSA in 2009 show that ready-to-eat (RTE) food - in particular, soft and semi-soft cheese, and fishery and meat products subjected to heat treatment -represents the most likely contaminated foodstuff. For this reason, the European Commission has developed (Dec. 2010/678/EU) a monitoring plan designed to evaluate the prevalence of L. monocytogenes in these products. The programme, developed in detail with reference to each member state, involved, among others, the city of Turin and has been set out from June to December 2011. The aim of this paper is to report the results obtained in the city of Turin. In total, 160 samples were analysed; only samples of smoked fish were found to be positive, while the pathogen was absent in cheese and meat products. © A.
