The purpose of this study was to examine the effects of an educational program regarding food safety for children. The data were collected from the results of a self-administered questionnaire that was given to 510 6th grade elementary school students in the Youngnam region who had undergone a food safety education program. The results of this study were as follows. First, the educational need for food safety was high in each food safety category, with the educational need for prevention against foodborne illness being the highest of the 10 categories. On the basis of the study results, educational materials were developed which targeted personal hygiene, food labeling, food purchase, food washing, food storage, cooking, foodborne illness prevention, food additives, endocrine disruptors, and illegal foods. Additionally, about 37% of the respondents aswered that they preferred the food safety education to be conducted at home. Second, the food safety education significantly improved the levels of knowledge and behavior of children toward food safety. These results imply that food safety education that addresses the concerns of children and their parents' is needed to improve the level of knowledge and behavior toward food safety.

Safety of present food has been accepted on the basis of extensive use experience for a long time. Many food resources have been developed by traditional techniques without any significant adverse impacts on the safety of food. Recently recombinant DNA techniques are being used to develop new food resources. These techniques enable developers to make specific genetic modifications in food resources that introduce substances that could not be introduced by traditional methods. With these techniques food resources are being to resist pests and disease, to tolerate herbicides, and to have improved characteristics for food preservation and nutritional contents. Because the properties of an organism results from interaction between biochemical pathways controlled by many genes, the genes conferring these traits usually encode directly responsible proteins for the new trait as well as proteins that indirectly modify carbohydrates or lipids in food. Therefore, this kind of food is regarded as new food that has not been existed before, and the safety of the food developed by recombinant DNA techniques should be evaluated upon scientific basis. In this paper, the issues upon safety of the food developed by gene manipulation are diseased in terms of composional changes that can be introduced, potential food safety harzards that might arise, present status of safety regulations in various countries and international organizations, and suggestions for the safety regulation in Korea.

Food is a kind of unconditional element for the health and survival of humanity. Eating is the most principle desire for humans among others, which can make humans feel stability and pleasure when the desire is well satisfied. The attention to food safety is increasing and food safety accidents are happening constantly, which makes the anxiety to food safety become more serious. Especially after the WTO, the floating of food hazards between countries are increasing, which makes the problems of food safety not just limited to inland but has become a matter of common interest internationally in this liberalization era. Therefore, institutional preparation and persistent management and supervision are necessary for increasing dietary life satisfaction as well as securing food safety. Meanwhile, the consumers also need to understand and trust the food safety information, and have the ability of personally pursuing a safe diet. In this study, sentiment index about food safety and dietary satisfaction were centered on Korean consumers and the factors having an effect on dietary satisfaction were analyzed. Moreover, whether the reliance to food safety information had a moderating effect on the sensory level of food safety and satisfaction to dietary food was also confirmed. The main results were different with those concluded by J. Yun and S. Joo (2014). The sensory level of food safety was decided by the reliance to food production distribution provision safety, anxiety to food varieties, and food token. The reliance to food production distribution provision safety was lower than the average level. The anxiety to food varieties was slightly higher than the average level. The reliance to food safety information was generally lower than the medium level which showed the distrust to food safety information. The satisfaction of diet by the consumers showed a slightly lower level than the average level. In addition, the reliance to food safety information had a moderating effect on the sentiment index about food safety and dietary satisfaction. Therefore, the consumer organizations or the government should actively expand various consumer education related to food safety in order to apprehend the concrete variables which can have effects on the satisfaction of diet and transform the precise information into accurate knowledge.

Due to the nature of HMR food that is susceptible to contamination, its safety management is becoming more important. The relevant food types in food code corresponding to HMR foods are addressed, and the criteria for hygiene indicator bacteria and food poisoning bacteria, and storage and distribution standards according to the product type were presented. The government's safety management for HMR foods is basically carried out through the Food Sanitation Act. Those who intend to do HMR business must complete business registration or declaration, hygiene education, health examination of employees, and comply with legal obligations such as HACCP application. The government confirms compliance with legal requirements through hygiene inspection and monitoring inspection of products. However, the safety of HMR foods is not realized by the safety management system alone. A food safety culture should be established in which industry workers and consumers carry out actions to ensure food safety.

To prevent food-borne diseases and ensure food safety, foodservice operators have been implementing the HACCP system in their facilities. Employees' knowledge of food safety can be improved through training and, as a result, their food safety behavior can be positively changed. A nonequivalent pretest and posttest control group model was designed to investigate the effectiveness of HACCP-based training on hospital foodservice employees' food safety knowledge and behavior, and to determine relationships between food safety knowledge and food safety behavior. The subjects used in this study were 84 hospital foodservice employees, assigned either to the intervention group (n=44) or the control group (n=40). Data were analyzed using the Statistical Package for the Social Sciences (SPSS). Descriptive statistics were computed, while the Student's t-test and ANCOVA (Analysis of Covariance) were used to investigate significant differences between groups, and the Pearson correlation was used to determine significant correlations. There were significant gains in both food safety knowledge and behavior, after the HACCP-based training. However, no significant correlation was found between food safety knowledge and food safety behavior. Based on this study we conclude that HACCP-based training is effective in improving both the food safety knowledge and food safety behavior of hospital foodservice employees.

Nitrate is a naturally occurring compound in plant and can be converted to nitrite in the nitrogen cycle and vice versa. Therefore, it is easy to find nitrate in plants including vegetables. Especially, it is known that high levels of nitrate found in leafy vegetables. Nitrate itself is relatively non-toxic but its metabolites and reaction products such as nitrite, nitric oxide and N-nitroso compounds, may produce adverse health effects such as methaemoglobinaemia and carcinogenesis. To execute the risk assessment of dietary nitrate and nitrite for the intake of vegetables, it is investigated that the levels of nitrate and nitrite in 23 vegetables (798 samples). The range of concentration were 0-6,719mg/kg for nitrate and 0-1,635mg/kg for nitrite, respectively. The Estimated daily intakes (EDI) were 0.85-1.38 mg/kg body weight/day for nitrate and 0.02-0.03 mg/kg body weight/day for nitrite by ages. We conclude that there are no health concerns for eating various vegetables since the EDI were below the Tolerable Daily Intake (3.7 mg/kg body weight/day for nitrate, 0.06 mg/kg body weight/day for nitrite) level established by WHO.
