Outline of Final Research Achievements

To suppress the food pollution by Escherichia coli O157 via cooking utensil, we examined the survival and resistance against disinfectant of the pathogen. The cells attached to the surfaces of cooking utensils lived for long time even in the tap water. The disinfectant-resistance of cells attached to the surfaces immediately increased after the initial attachment. Polysaccharides among food components markedly stimulated the initial attachment and biofilm-formation of the cells.
