Description	This study was done to determinate the disinfectants effect of Savo (SV), chlorine compound, and benzalkonium chloride (BC) on biofilm and planktonic cells in 23 strains S. aureus mainly food isolates. The biofilm formation was performed in a model system using microtiter polystyrene plates COSTAR 3797 in trypton-soy broth with 1 % glucose at 30 °C. Benzalkonium chloride (BC) at 125 mg/l, applied directly on 24 hours old biofilm, was able to remove the biofilm matrix in 21 strains, while to devitalise biofilm cells in 23 strains. BC at 125 mg/l was the lethal concentration to planctonic cells, coincubated for 24 hours or treated for 10 minutes. None of the studied strains was able to grow in SV at 1X recommended concentration, while the safety lethal concentration for planktonic cells treated 10 minutes was 4X. Application of 4X concentration SV into the 24 hours old suspension removed biofilm matrix in all strains and devitalised biofilm cells in 10 strains and inhibited their viability in the 13 strains by 70 %.
