Abstract

This study evaluated bactericidal efficacy test of sanitisers for benzalkonium chloride, sodium hypochlorite and peracetic acid, determined minimum inhibitory concentration (MIC) of sanitisers and assessed their effect on the reduction of biofilms produced by Staphylococcus spp. strains isolated from organic and conventionally produced Minas Frescal cheese dairy products. The MIC was determined at three different contact times (5, 10, and 15 min). Biofilms formed on stainless steel and the efficiency of sanitisers in removing the biofilms were investigated at contact times of 5 and 10 min and incubated for 24 and 48 h. All strains tested were able to form biofilm within 24 and 48 h for all evaluated sanitisers, indicating the MIC used in this study was not sufficient to inactivate biofilm formation. Therefore, the MICs obtained through the analysis of the microorganism in its planktonic form were not efficient to eliminate the biofilms formed. (C) 2021 Elsevier Ltd. All rights reserved. (AU)
