Objective: This study was conducted to investigate the hygienic state and awareness of drink vending machines in a city.
Methods: Twelve of the most frequently used vending machines in various areas were selected in October 2008. As soon as fresh samples of milk coffee and adlay tea were collected in sterile containers from each machine, the temperature was measured. The samples were carried on ice to the laboratory to test total plate counts and Escherichia coli contamination. College students were inquired about drink vending machine hygiene by implementing self-developed questionnaires.
Results: The temperature of 6 milk coffee samples (50.0%) and 8 adlay tea samples (66.7%) turned out to be inadequate. The total plate counts of milk coffee samples were all adequate, although 9 adlay tea samples (75.0%) were inadequate. All the beverage samples were negative for E. coli. In questionnaires obtained from 74 users of coffee vending machines, only 2 (2.7%) expected the hygienic state of vending machines to be good. There were 27 people (33.3%) that knew the existence of hygiene-related laws for vending machines.
Conclusions: This study reveals that the hygienic state of drink vending machines insufficiently reaches the standard for the hot beverage and that most people are not aware of importance of vending machine hygiene. It is necessary to make improvement in the hygiene of vending machines and public awareness in this city.
