Biofilms constitute a physical barrier, protecting the encased bacteria from detergentsand sanitizers. The objective of this work was to analyze the effectiveness of sodium hypochlorite(NaOCl) against strains of Staphylococcus aureus isolated from raw milk of cowswith subclinical mastitis and Staphylococcus aureus isolated from the milking environment(blowers and milk conducting tubes). The results revealed that, in the presence of NaOCl(150ppm), the number of adhered cells of the twelve S. aureus strains was significantlyreduced. When the same strains were evaluated in biofilm condition, different results wereobtained. It was found that, after a contact period of five minutes with NaOCl (150ppm),four strains (two strains from milk , one from the blowers and one from a conductive rubber)were still able to grow. Although with the increasing contact time between the bacteriaand the NaOCl (150ppm), no growth was detected for any of the strains. Concerning theefficiency of NaOCl on total biofilm biomass formation by each S. aureus strain, a decreasewas observed when these strains were in contact with 150 ppm NaOCl for a total period of10 minutes. This study highlights the importance of a correct sanitation protocol of all themilk processing units which can indeed significantly reduce the presence of microorganisms,leading to a decrease of cow´s mastitis and milk contamination.This study was supported by Portuguese Foundation for Science and Technology (FCT) through the grant SFRH/BPD/20987/2004 attributed to Cláudia Botelho and thanks to FAPESP (Fundação de Amparo a Pesquisa do Estado de São Paulo) for the scholarship attributed to Poliana de C.
