Prevalenza di listeria monocytogenes negli stabilimenti di produzione di prodotti a base di latte: un nuovo approccio per il controllo ambientale

Soft repined cheeses have often been subject of community alerts; that explain why Lombardy Region, as part of the activities planned by Expo 2015 event, provided the activation of an integrated system of official controls, in order to contain Listeria monocytogenes in dairy products. The aim of this work is to present the preliminary results of environmental monitoring, done during the first half of 2013, in order to identify factors able to contrast the contamination and subsequent multiplication of L. monocytogenes in this type of food. It’s been observed that surfaces with more chance of a unfavorable outcome, both in first that in second trimester (2013), are those relating to maturing rooms (shelves, boxes, etc.) and portioning and packaging environments.
