Abstract
The purpose of this study was to determine the rate of glove changing by mobile food vendors after monetary transactions, and the presence of bacterial contamination on a sample of dollar bills obtained from 25 food vendors near five hospitals in Manhattan, New York City. During 495 monetary transactions observed there were only seven glove changes performed by the workers. Eleven of 34 food workers wore no gloves at all while handling money and food. Nineteen of 25 one-dollar bills collected (76 %) had 400 to 42,000 total bacterial colony-forming units. Colonies were of varied morphology and size. Of these 19 samples, 13 were selected (based on level of growth), and tested for the presence of coliform bacteria, which was found in 10 of the 13 samples. Effective strategies to monitor and increase glove wearing and changing habits of mobile food vendors are needed to reduce risk of foodborne illness.
