and third evaluation showed that total microorganisms of all dish washing sponges were 2.3 x 107 – 1.0 x 109,
3.5 x 107– 5.3 x 109 and 3.6 x 107 – 3.0 x 109 CFU/g, respectively. The MPN/g of coliforms were 530 – >1,100 ;
530 – >1,100 and 750 – >1,100 ,respectively. The MPN/g of E. coli were 30 – 230, 30–150 and 62– 430,
respectively. Due to the fact that there is not any definite criterion for microbiological quality standardization of
dish washing sponge ,comparison with the criteria of microbiological quality standard of ready-to-eat foods and
food utensils of Department of Medical Sciences, Ministry of Public Health of Thailand is selected. In comparison
with the standard mentioned above,all samples included in this study showed more quantites of total
microorganisms, MPN/g of coliforms and E.coli, suggestive of the possibility that all dish washing sponges might
spread foodborne diseases to consumers.
