Decontaminazione di superfici di strutture e attrezzature utilizzate in aziende alimentari attraverso l’impiego di apparecchi ionizzatori

The AA aim was to decrease the microbial concentration of the surfaces of rooms or items of food factories, by a ionization system. The surfaces of these rooms or items were treated with ionizer machine (SitalKlima company) for twentyfour hours. Suspensions of Escherichia coli, Listeria monocytogenes, and Saccharomyces cerevisiae were intentionally plated on different surfaces simulating the surfaces of rooms or items. After the treatment less than 1% of the initial microbial population added was detected. So, after ionization, the concentration of such population on the surfaces was less than 1 log unity/cm2, demonstrating that the treatment allowed to reach acceptable values of surface contamination for food industry.
