Abstract
Gloves can serve as barriers to decrease the transfer of microorganisms from hands to food. Glove changing by food vendors is particularly important when handling paper currency, as bills can carry and transmit microbes from person to person. The purpose of this study was two-fold: (1) To ascertain the extent to which gloves are changed after monetary transactions in food vendors at a major mall in New Jersey; and (2) to document the level of bacterial contamination and the presence of coliform bacteria on paper currency handled by these vendors. This study was conducted with two phases: Phase 1, in which 10 min of observation of food workers was completed followed by a monetary sample collection and testing, and Phase 2, in which 1 h of observations were conducted. During Phase 1, gloves were changed after 4 (2.3%) of the 174 transactions. All the dollar bills collected from all 17 vendors during Phase 1 exhibited bacterial contamination. The number of CFUs ranged from 1.18 × 107 to 1.13 × 1010, and bills collected from 6 of the 17 vendors (35.3%) tested positive for coliform bacteria. In Phase 2, gloves were changed after 3.35% of the 1193 transactions observed. This study makes the critical connection between the lack of compliance by food workers with the health code, and the contaminated money they may be handling while dispensing food.
