The purpose of this study was to investigate cook′s duties in the School Foodservice law, comparing with those of other countries and to suggest the more useful details of cook′s duties. As a result of this study many things of the cook′s duties in the School Foodservice law have to be changed. If then, the gap of the School Foodservice law and Food Sanitation law will be decreased, logical application of two laws could be possible and a lot of cook′s abilities could be enoughly used. Compared with other countries, cooks can be responsible officials in the School Foodservice. Suggestions about cook′s duties in the School Foodservice law are as follows. 1. Not only dietitian but also cook should be subscribed as a responsible official in the School Foodservice law. 2. Not only the duties of dietitian but also those of cook should be subscribed in the School Foodservice law. 3. Cook as a responsible official of School Foodservice should investigate the food as well as dietitian. 4. Dietitian teaches cook and assistant cook how to cook presently by the School Foodservice law, but cook should teach how to cook because cooking is cook′s major and cook gets the national certificate of cooking. 5. Cooks do job under dangerous circumstances, so extra money should be paid to cooks. 6. Even if not being described in the law and education of sanitation is presently done in the cook′s reeducation, dietitian educates sanitation to cook, so it has to be changed. Cook can educate sanitation to other workers in the School Foodservice. 7. The name of office room in the School Foodservice systems "dietitian′s room" should be changed to "Foodservice office room". If those suggestions are accomplished, cooks and dietitians can cooperate effectively and respectfully and the better School Foodservice can be served to students.
