This study was carried out to investigate foodservice management practices of 100 child care centers nationwide, and to provide background information for developing foodservice management policies at child care centers. Approximately 20% of the child care centers had a separate dining room; most of the centers were vulnerable to sanitation or safety problems. The percentage of the centers that planned menus was about 60% and 10% established standardized recipes. Fourteen percent of the centers kept records for distribution and menu evaluation and 33% kept sanitation management records. Since only 7% of the centers employed a dietitian, foodservice in most centers were not managed by professionals. The results of menu assessment revealed that 56.5% of the national/public child care centers received 19 points or higher out of 21 points, whereas 5.6% of the private child care centers received the same scores. Proper usage and storage of raw food, sanitary management of equipment and facilities, waste management/leftover food treatment, and basic facility of cooking zones were performed well by many centers. The overall scores of foodservice performance were only 31.2 out of 60 points, representing relatively poor safety management, food procurement management, and facilities and equipment management. These results indicate that the foodservice management of the child care centers are in a relatively poor state. Since nutrition management of the most centers was performed by non-professionals, it may not be possible to provide proper nutrition for health and normal growth of preschool children and to perform efficient nutrition education programs. The following suggestions are strongly recommended in order to improve foodservice performance at child care centers. First, foodservice administration should be performed by a dietitian, and second, efforts should be focused on strengthening nutrition and sanitation management.

The purpose of the study was to investigate the effects of the characteristics of dietitians, the characteristics of school food services, equipment ratio of HACCP facility/equipment and perception of barriers to HACCP implementation on external and internal audit of food safety/sanitation management performance in school food service. An e-mail survey was conducted with 144 dietitians in Gyeongbuk Province. A response rate was 57.6% (N = 83) and data was analyzed using SPSS windows (ver. 12.0). Dietitian perceived facilities/equipment-related and stakeholder-related as the big barriers in implementing a HACCP system. Total scores of sanitation/safety management performance for external and internal audit were similar at 92 and 91 out of 100, respectively. 'Facilities/equipment' and 'HACCP system' categories in both external and internal audit were rated the lowest. As dietitian perceived facilities/equipment-related (p < 0.001) and stakeholder-related (p < 0.05) barriers to HACCP implementation were greater, the scores of the external and internal audits were significantly lower. As dietitian perceived barriers for all categories were greater, the scores of internal audits were significantly lower (p <0.05). As a result of multiple regression analyses, the scores of the external audit was positively associated with career as a school food service dietitian, but was negatively associated with barriers related to facility/equipment, while the scores of the internal audit was negatively associated with barriers related to facility/equipment and employees. This study suggests that supporting programs on securing the facilities/equipment and employee training are needed for successful HACCP implementation in school food service.

This study was conducted to develop and evaluate food safety training program for employees in foodservice operations. The developed CD-ROM was consisted of 5 parts: foodbome illness, personal hygiene, food handling in food production steps, HACCP system, and sanitary facilities. It has made slides for all contents, the animation and movie to raise interests and concentrations, and illustrations and pictures to understand. The evaluation checklists were developed 15 questionnaires including understanding(5), information(3), concentration(4), recommendation(2), and the most important factor(1) and measured by Likert 5-point scale. Fifty-four dietitians in Daegu and Gyeongbuk schools, hospitals, and industries foodservice operations responded to the surveys. The results are as follows; The most important part in the CD-ROM was personal hygiene(33.3%). The total mean was $3.95{\pm}0.41,\;3.91{\pm}0.46$ on understanding, $3.89{\pm}0.50$ on information, $3.87{\pm}0.55$ on concentration and $4.29{\pm}0.49$ on recommendation. The score was significantly higher in the recommendation part than others. Overall, as the developed CD-ROM has achieved fine score, a study on the effect of education needs to be followed. Moreover, consistent and organized education by developing a variety of sanitation education methods should be conducted.

The purpose of this study was to propose HACCP system implementation properly and to secure the food safety of school foodservices in Pohang city since the proper facilities and equipment should be key factors in food safety and production. So this study was designed to evaluate existing equipment in food production area, receiving and dining area, and employee facilities. Questionnaire was mailed to 107 school foodservice dietitians in Pohang area and 97 were responded (90.7% response rate). Approximately sixty percent of foodservices were not available separate receiving or polluted area, fifty one percent were installed screen door for insecticidal and temperature and humidity control, and these environmental conditions were hard to keep kitchen dry and sanitary condition. Usually public schools were better equipped than private schools. Forty three percent of school foodservice had initial use of non-foodservice, opened before 1994, and thirty three percent of elementary school foodservice. Among employee facilities, hand washing sanitation stand was prepared seventy nine percent (78.9%) of school foodservices. Dietitians chose outworn equipment and facilities (30.9%), difficulties of maintaining standard temperature and humidity for foodservice (20.6%), lacking separate receiving or polluted area (13.4%), indirect contamination of water hoss (10.3%), and lacking employee facilities (10.3%) as critical points to correct in school foodservice. Therefore governmental regulating agencies must review and approval of plans prior to new construction or extensive remodeling of school foodservice facilities. In addition to these requirement, plan must be set-up step by step to implement HACCP system properly.

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.

This study evaluated the abundance of fecal coliforms in oysters Crassostrea gigas, sea squirts Halocynthia roretzi and sea cucumbers Apostichopus japonicus in fisheries along the coast of Korea in 2014, and investigated the prevalence of antimicrobial resistance in Escherichia coli isolated from these fishery products. The ranges of fecal coliforms found in oysters, sea squirts and sea cucumbers were <18-20, <18-330 and <18-3,300 MPN (most probable number)/100 g, respectively. Sea squirts contained the greatest range of E. coli (<20-140 MPN/100 g), followed by sea cucumbers (<20-130 MPN/100 g) and oysters (<20-20 MPN/100 g). A total of 26 strains of E. coli were isolated from 34 sea squirt, 25 sea cucumber and 13 oyster samples. Strains thus isolated were tested for their susceptibility to 22 antimicrobial agents used in Korea for medical or veterinary therapy. E. coli isolates showed the greatest resistance to ampicillin (84.6%), followed by trimethoprim (34.6%), nalidixic acid (34.6%), tetracycline (30.8%), pipemidic acid (26.9%), streptomycin (23.1%), chloramphenicol (23.1%), trimethoprim/sulfamethoxazole (23.1%), and gentamicin (15.4%). Resistance to at least one antimicrobial agent was present in 88.5% of E. coli isolates. Of the 26 isolated, six strains (23.1%) were resistant to multiple antimicrobial agents.

This study was performed to develope mathematical models for predicting growth kinetics of Staphylococcus aureus in the processed meat product, pyeonyuk. Growth patterns of S. aureus in pyeonyuk were determined at the storage temperatures of 4, 10, 20, and $37^{\circ}C$ respectively. The number of S. aureus in pyeonyuk increased at all the storage temperatures. The maximum specific growth rate (${\mu}_{max}$) and lag phase duration (LPD) values were calculated by Baranyi model. The ${\mu}_{max}$ values went up, while the LPD values decreased as the storage temperature increased from $4^{\circ}C$ to $37^{\circ}C$. Square root model and polynomial model were used to develop the secondary models for ${\mu}_{max}$ and LPD, respectively. Root Mean Square Error (RMSE) was used to evaluate the developed model and the fitness was determind to be 0.42. Therefore the developed predictive model was useful to predict the growth of S. aureus in pyeonyuk and it will help to prevent food-born disease by expanding for microbial sanitary management guide.

This study was designed to evaluate the sanitary characteristics of sea water in a part of the south coast, Korea and to check the seawater which is in compliance with the recommended bacteriological criteria for shellfish cultivation. The samples of sea water were collected at 14 sampling stations established in the survey area between March 2014 and October 2014. Food poisoning caused by seafood consumption is often associated with pathogenic microorganisms originated from fecal contamination. Therefore, fecal coliform is very important criteria for evaluating the safety of fisheries in coastal areas. The range of geometric mean (GM) and the estimated 90th percentile values of total coliform were 4.1~83.1 MPN/100 mL, and 11.7~834.1 MPN/100 mL, respectively. The GM and the estimated 90th percentile values of fecal coliform were 2.5~22.7 MPN/100 mL and 2.5~170.0 MPN/100 mL, respectively. Therefore, the bacteriological safety of seawater at this shellfish-growing area met with the Korean Shellfish Sanitation Program (KSSP) criteria for a growing area. However, the values are seasonally exceed the KSSP criteria, suggesting that the monitoring and evaluation of seawater quality is very important in shellfish-growing area.

The influences of inland pollution sources nearJeokyang and Jangpoports following rainfall events on the bacteriological water quality and safety of commercial shellfish were investigated in the Changseon area, Korea. Stream flow rates exhibited 1.9- to 5.7-fold increases after rainfall events and then fell to 68~81% of that level after 24 h. The calculated impact area of inland pollution sources was 0.47 $km^2$ in the Jeokyangport area and 0.27 $km^2$ in the Jangpoport area at 24 h following 11 mm of rainfall. When the flow rate of inland pollution increased, the level of male-specific bacteriophage (MSB) decreased, and no MSB could be detected in seawater samples, whereas 30 PFU/100 g was detected in shellfish samples. Fecal coliform levels in seawater and shellfish samples did not exceed their respective tolerance levels (4.5 MPN/100 mL) and 130 MPN/100 g, respectively and thus complied with the standard for approved shellfish growing area. The sanitary conditions of areas adjacent to Jeokyang and Jangpoports under conditions of rainfall below 29 mm met the criteria for approved growing area under the United States National Shellfish Sanitation Program and the EC Regulations.
