Adhesion inhibition and antibacterial activities of 13 kitchen detergents were determined against S. Enteritidis IFO3313, P. aeruginosa NBRC 13275, P. fluorescens No. 3 and L. monocytogenes No. 185. All the detergents tested inhibited the adhesion of S. Enteritidis IFO 3313 to micro-plates more than 50% at 0.025% (W/V), without a decrease in viable counts. Adhesion of P. fluorescens No. 3 was inhibited more than 50% by 2 detergents even at 0.0025% (W/V). Four detergents completely inhibited the adhesion of tested bacteria, except for P. aeruginosa NBRC 13275, at a concentration lower than that recommended for washing vegetables. Adhesion inhibition activity appears higher in detergents containing linear alkylbenzene-sulfonates and polyoxy ethylene alkyl ether sulfonates but not alkylamine oxides.
