This research is aimed at evaluating the nutrition knowledge and hygiene knowledge of people who are either foodservice employees or housewives and at providing data for conducting hygiene education by comparing the differences between the two groups. Both groups scored relatively high in nutrition knowledge with housewives scoring 9.9/12 and food service employees scoring 9.6/12. However, foodservice employees scored significantly higher in hygiene knowledge and degree of practice than housewives, A correlation was found between nutrition knowledge and the degree of hygienic practice and a significant correlation between hygiene knowledge and the degree of hygienic practice. The higher the hygiene knowledge was, the higher their degree of hygienic practice was. As for food hygiene information, foodservice employees obtained the information through hygiene education and lecture meetings, but housewives got their information through mass media. To summarize, mass media, which housewives can have easy access, must have programs for housewives to help them improve food hygiene in cooking, and programs for foodservice employees on washing food.
