Abstract

An uncleaned food table which may contain bacteria can be considered as one factor in food contamination. A clean cloth was used to resolve this certain problem, the presence of bacteria can be a source of foodborne illnesses. This cleaning cloth may either reduce the number of bacteria present on the table or increase the number of bacteria that may also be a source of bacterial contamination. Five (5) tables located in selected food stalls beside Animo Center in DLSMHSI were swabbed before and after wiping with a cleaning cloth. The process of serial dilution was used, and a standard plat count was performed. Upon the detection of bacteria before wiping the table, it was found out that 60% have no bacteria at all and 40% had 1-29 CFU. Meanwhile, after wiping the table, 80% resulted to no bacteria and 20% were too few to count. These results indicate that there was no significant number and no significant difference on the number of bacteria present before and after wiping with a cleaning cloth on the surface of tables located in selected food stalls beside Animo Center in DLSMHSI.
