- W632140917 abstract "This study examined transfer of bacteria from mouth to different surfaces (spoon, chopstick, hand) and from surfaces to food (chicken broth, rice). Three different sets of experiments were conducted. In the first experiment, bacterial transfer from mouth to utensils (spoon or chopstick) was determined. The second experiment measured bacterial transfer from mouth to broth and included scooping and stirring with a spoon. In the third experiment, bacterial transfer from mouth to food rice was tested using either spoon or hand. Ten or seven subjects were used for each of the three experiments. Results indicated that there was a transfer of approximately 5 log10cfu of total bacteria to the spoon or chopstick when either was placed in the mouth with or without food. Between 4 and 5 log cycles of bacteria were transferred to broth when the spoon was placed in the mouth six times while eating. Approximately 1 million bacteria were transferred each time from mouth to rice by using hands. More than 5 log cycles were transferred to the rice when the spoon was used to consume the rice then placed back in the bowl for 5 cycles. There were high numbers of bacteria transferred to the common bowl of rice when a spoon was used however much lower number than when the hand was used. The overall conclusion was that significant bacterial transfer from mouth to utensils (spoon or chopstick) and from mouth to food occurred when utensils or hands were placed back into food after consumption." @default.
