  • This study performed microbiological hazards analysis in raw food materials, cooking processes, kitchen staff, utensils, and the environment in order to obtain contamination levels of S. aureus in school foodservice operations. S. aureus was not detected in cooked foods offered by the foodservice operations; however, it was found in raw food materials prior to cooking. In the case of vegetables, S. aureus was detected in washed mung bean sprouts, parboiled mung bean sprouts, and bellflower roots both before and after disinfection, at levels of 2.2, 1.0, 1.0, and 1.0 log CFU/g, respectively. For processed foods, S. aureus was detected in one sample of packaged bean curd as well as in mung bean jelly cake at the level of 1.5 log CFU/g. For meat products, S. aureus was detected in beef brisket and chicken at levels of 2.3 and 1.3 log CFU/g, respectively. To determine microbiological hazard data for the hands and gloves of cooking personnel, the staff members were divided into two groups: a group presenting Enterobacteriaceae or coliforms, and another group presenting neither Enterobacteriaceae nor coliforms. The results showed that S. aureus was detected on the hands of staff in each group at levels of 2.0 and 2.1 log CFU/hand, respectively, and at 1.8 and 0.0 log CFU/hand on the gloves of staff in each group, respectively. Among kitchen utensils, as an environmental factor in school foodservice operations, S. aureus was detected on meat knives, mixing bowls, and dish cloths at levels exceeding 1.0 log CFU/hand.

  • Purpose: This study was conducted to examine prerequisite-program performance of the hospital foodservice operation and develop measures for improvement of prerequisite-program performance. Methods: Data were collected through surveys administered to 168 hospital dieticians in the Seoul, Incheon, Gyeonggi-do, Daegu, and North Gyeongsang areas. Out of total questionnaires, 65 questionnaires were usable and the response rate was 38.7%. Statistical analyses were performed using the SPSS program (ver 20.0) for ${\chi}^2-test$ and one-way ANOVA. Results: According to the result of the prerequisite-program evaluation, the percentage of 'appropriate', 'needs to be improved', and 'inappropriate' was 44.6%, 47.7%, and 7.7%, respectively. The score for the 'inappropriate' group was significantly lower than that of the 'appropriate' group or 'needs to be improved' group on the food safety management (p < 0.001), preparation facility management (p < 0.001), water management (p < 0.001), and storage transportation management (p < 0.05) parts. Holding rate of foodservice facility and equipments in the 'appropriate' group were significantly higher than in the others on convection oven (p < 0.01), air conditioner (p < 0.01), three-compartment sink (p < 0.01), hot-holding equipment (p < 0.01), cold-holding equipment (p < 0.05), exclusive thawing refrigerator (p < 0.05), and sterilizer for sanitary shoes (p < 0.05) items. Conclusion: To improve the quality of hospital foodservice, foodservice managers and HACCP specialists should develop and implement a prerequisite-program and a HACCP plan considering the characteristics of the hospital foodservice operation.

  • The purposes of this study were to find factor which influence on the selection criteria of food supplier. Questionnaire were distributed to 52 general hospitals with more than 400 beds located in Seoul and Kyongin province, and responded questionnaires were collected from 44 dietetic departments (84.6%) and 18 purchasing departments (34.6%). The main results of this study can be summarized as follows: (1) supplier selection criteria include quality, service, cost and supplier competency. (2) With having been met with tight competition and market opening, hospitals plan a strategy to improve quality, service and they tend to have more interest in various supplier selection criteria. (3) Purchasing departments estimate more highly the rate of reflection in considering supplier selection criteria than the rate of importance about cost criteria, which reveals that purchasing departments sensitively respond to cost cutdown. (4) When selecting suppliers, a significant(p<.01) influence of stability of supplier industry environment on the selecting criteria such as the importances of quality, service, and supplier quality are recognized only after recognizing the stability of food delivery industry. Food supplier industry secures stability more quickly through major companies' participation in food distribution industry and this will reveal the importance of supplier selection criteria. (5) Suppliers which are selected by the quality criteria, service criteria, supplier quality criteria make efforts to communicate with foodservice departments, to give more proper information about substitute food, new product, and to make commitments, while suppliers which are decided by cost criteria do not establish supportive relationships with foodservice departments.

  • This research was performed to acquire dietitians' attitudes toward events marketing at school foodservice operations in the Busan area. A total of 359 questionnaires were distributed to dietitians employed at school foodservice operations in Busan from July 1 to 31, 2006 (response rate: 93%). All dietitians assessed the importance and performance of event marketing at 3.39/5.00 and 2.78/5.00. The elementary and high school had significantly (p<0.01) higher average scores of performance of event marketing than those of the middle school. The contract managed foodservices had significantly (p<0.01) higher average scores of performance of event marketing than those of the independent managed foodservices. In the Importance-Performance Analysis (IPA), high importance and high performance (B area: doing great) were seasonal event, traditional festival day event, subdivisions of the seasonal event, environment event, school event, the day event and high importance whereas low performance (A area: focus here) was health event. Event marketing increased customer satisfaction and confidence. Therefore, these results suggest that there may be a need to implement special events at school foodservice in order to increase students' satisfaction.

  • In order to evaluate the microbial safety of the foodstuffs and manus in regards to foodservice operations, the total of 1,051 samples of drinking waters, vegetables, and cooked foods were collected. Total viable count (TVC), coliform group, and pathogens were analyzed. Twenty five percent samples of 441 drinking waters showed high contamination of above 2 log CFU/g TVC. Twenty percent of the waters were contaminated by above one log CFU/g coliform. Forty percent of non-heated food, Moochim, were contaminated by above 5 log CFU/g TVC and 26% of Moochim were contaminated by above 2 log CFU/g coliform. Bacillus cereus and Eschericia coli were detected on boiled rice and kimchi, and B. cereus was detected with a high ratio. Therefore, the foodstuffs and manus regarding foodservice operations appear to be generally safe. However, efficient microbial control for drinking water and Moochim-style food is necessary and in particular, careful management to reduce microbial contamination should be applied to drinking water.

  • In this study, vinegar disinfection was evaluated as a novel method for the preparation of raw food ingredients used in foodservice operations. The test materials were washed and disinfected using three different methods, and were then stored at temperatures of $3^{\circ}C\;and\;10^{\circ}$ for 7 days; Following storage, physicochemical and sensory characteristic comparisons were performed. Temperature for all test materials ranged between 15.2-20. $9^{\circ}C$, water activity was maintained near 0.96, and the pH levels of the samples were 6.44, 6.29, and 6.35, respectively. Residual chlorine levels were generally low, ranging between 0.01 and 0.02. The physicochemical qualities of the samples were evaluated according to the storage method and temperature. Brightness(L value), redness(a value), and yellowness(b value) tended to increase with increasing storage time. The evaluated sensory characteristics included appearance, color, smell, taste, texture, and overall acceptance. With regard to storage temperature the vinegar-treated samples were evaluated as superior, receiving a score of 7.00, and the ingredients stored at $3^{\circ}C$ were evaluated as significantly (p< 0.001) superior to those stored at $10^{\circ}C$. Overall, vinegar is an effective disinfectant to apply in the preparation of raw vegetables that are typically served without heating, and which can cause serious food safety issues when contaminated.

  • The microbiological examinations of food service operations were conducted for the hygienic evaluation at four elementary schools in Busan, Korea. Total one hundred and seventy two swabbed samples using sponge were collected from the surface of environments, utensils and equipments of food service facilities and analyzed by measuring the total, coliform and psychrotrophic count. Sampling sites were the surfaces of floors, drains, walls, knives, cutting boards, rubber gloves, vinyl aprons, plastic containers, carriers, shelves, trays, dry shelves, electric tray dryer, food containers, soup containers, rice cookers, frying pans, boiling cookers, refrigerators, dumb waiters and dishwashers. The swabbed samples kept in an ice-parked box were transported to a laboratory and analyzed. The results demonstrated that the degree of contamination depended on the sampling sites. Averages of total counts of surface swab samples were ranged from 0.62 to 7.79 Log CFU/200 cm$^2$. The level of coliforms were ranged from not detectable to 5.26 Log CFU/200 cm$^2$, and those of psychrotrophs from not detectable to 6.15 Log CFU/200 cm$^2$. The severely contaminated sites were dumb waiters, drains, rice cookers, knives, plastic containers and floors. Also cutting boards, rubber gloves, carriers, drying shelves, vinyl aprons, boiling cookers, soup containers, frying pans and refrigerators were highly contaminated with the level of abode 3.5 Log CFU/200 cm$^2$. Therefore, those sites should be focused and controlled according to control points of sanitation standard operating procedures (SSOP). Also, periodic microbiological examination in addition to visual examination is recommended on these highly contaminated sites indicated above results at food service operations in elementary school.
