Abstract : The aim of this study is to evaluate the occurrence of Staphylococcus aureus in some restaurant workers in general restaurants of Jeddah city, Kingdom of Saudi Arabia. The effect of some commercial soap, detergents and some plant water extracts on the growth of bacteria was studied. In this study, different types of bacteria were isolated from hands, nostrils and saliva of 72 workers from 32 general restaurants in Jeddah. The occurrence percentage of bacteria Staphylococcus sp. was (23.72% to 72.32% ), (11.36 to 92.04%) and from(12.25%-94.54%) to 94.49 in nostril, fingernails and the saliva respectively. S. aureus was identified using bacteriological and biochemical tests. Two isolates of S. aureus from fingernails of two workers were found resistant to 15 antibiotics and another isolate from nostril resistant to 8 antibiotics. The results revealed that, some commercial liquid soaps used in dish and other restaurant tools washing, inhibited S. aureus isolates depending on types of soaps, concentrations and isolates used in the study. It was found that two dry gelatin hands detergents not inhibited bacteria isolates in addition to the control, while the third type of these detergents inhibited the growth of 4 isolates only and the control. However, commercial detergents with 100% concentrations inhibited all the isolates. while detergent 1 &2 inhibited some isolated in addition to the control S. aureus ATCC 29213. Black and green tea extracts had no effect on the growth of S. aureus only more than 40 % concentrations. Green tea extract of 60% inhibited most of the isolates. Concentrated lemon extract was found to be more effective in inhibition of all isolates. It was noticed that concentration of 60, 70, 80, 90 and 100 of lemon juice, bactericidal of S. aureus isolates.
