The purpose of this study was to analyze the personal hygiene status of foodservice employees as well as microbiological counts of their hands according to food safety education. A survey was conducted for employees who worked at five foodservice facilities, and the results of the survey were assessed using the SAS program (ver. 9.3). A total of 20 employees' hands were sampled to analyze aerobic plate counts (APCs), coliforms counts (CCs), and Staphylococcus aureus. The food safety education program was composed of four education sessions, including microbiological evaluation of employees' hands. According to the survey results, all employees wore a sanitary uniform, hair cap, and shoes. However, 96% of employees used the restroom wearing sanitary shoes, whereas just 20% of them washed their hands using the standard method. Additionally, employees washed hands after using the restroom (100%), before using single-use gloves (76%), after eating (76%). The results of the microbiological hazards analysis of foodservice employees' hands showed that the average numbers of APCs and CCs before cooking were 5.53 log CFU/hand and 2.95 log CFU/hand respectively, whereas the average numbers of APCs and CCs while cooking at foodservice facilities were 6.49 log CFU/hand and 3.29 log CFU/hand, respectively. Staphylococcus aureus was detected in 10% of their hands before cooking and 5% of their hands while cooking. The average numbers of APCs and CCs were significantly reduced before cooking as well as while cooking, and Staphylococcus aureus was not detected in any of the samples as the frequency of food safety education increased. In conclusion, this study shows that it is necessary for foodservice employees to regularly participate in food safety education with effective instruments in order to improve their hygiene level.
