Abstract

This study aimed to enumerate coagulase positive staphylococci in 404 samples of milk and dairy products collected in own-checks or during the official controls from different dairy industries in Central Italy. These microorganisms were detected using ISO 6888-2:1999/Amd. 1:2003 and only when they exceeded 105 CFU/g, staphylococcal enterotoxins were also investigated. Own-checks samples were resulted always below the detection limit. Among those collected by Competent Authorities in the frame of official controls, provola (100%) and mozzarella (22.9%) samples showed mean values of 1.8x102 and 2.8x105 CFU/g, respectively. These values exceeded the maximum limits set by Commission Regulation (EC) No 2073/2005, resulting in request of hygiene improvements in the first case, and withdrawn of mozzarella samples due to the presence of staphylococcal enterotoxins. Then, the monitoring of CPS incidence in dairy products represents an important tool for public health in order to avoid the occurrence of food borne outbreaks.
