  • The goal of this study was to examine the effects of perceived risks toward GMO (Genetically Modified Organism) food on the decision-making to purchase it and demands to reveal its Identity. The major results were as follows. First, consumers strongly perceived the risk toward GMO food, and demanded labeling to identify it. But, many consumers had indecisive in the purchase of GMO food. Second, consumers with high level of perceived risks toward GMO food were more likely not to buy GMO food. In addition, the level of perceived risk was high among consumers who had many children. Finally, consumers with high level of perceived risks toward GMO food were more likely to demand the labelling for identifying GMO food. Consumers who had many children and high level of reliability for labelling food safety strongly demanded to label for revealing GMO food.

  • The goal of this study was to examine which factors influence consumers' demands to reveal the identity of GMO(Genetically Modified Organism) food, risk perception, and decision-making to purchase it. Consumers perceived its risk, and demanded labeling to identify it. Not many consumers wanted to buy GMO food. The results also revealed as follows. First, the level of demand to label for identifying GMO food were high among female consumers, consumers with negative attitude, and consumers severly perceived its risk. The level of perceived risk was high among consumers who were old and had high income, exercised their own healthy programs, showed negative attitude toward GMO food, and demanded strongly for labelling. Second, old consumers, consumers with high income, consumers concerning more about health, consumers with negative attitude and strong demand to label for identifying GMO food were more likely to perceive risk highly for GMO food. Third, consumers' attitudes and the level of perceived risks for GMO food significantly influenced the decision-making to purchase GMO food. However, other variables turned out not to affect consumers' decision-making to purchase it.

  • The objectives of this study were to review various aspects of society on Genetically Modified Organism(GMO) in the view point of environmental sociology. There were many assertions related to GMO, and application of biotechnology. Some people assert GMO as harmful to human health, and some people as not harmful, however, there were no proven evidences to report. Through the literature review, this study intended; 1) to identify the present condition of GMO, 2) to weigh the pros against cons of views on GMO, 3) to study an aspect of society on GMO, and 4) to assert its necessity to mark GMO or not, because citizens have a rights to know natural or GMO. Based on the conclusions of this study, following recommendations were offered: 1) To review continually the GMO in the view point of environmental sociology especially in the areas of food safety, biosafety, trade, and public research investment, and 2) further detailed studies of GMO may necessary to ensure safety to human health and environment.

  • The GMO (Genetically Modified Organism) labeling system on raw materials has been in Korea since March 2001, and genetically modified organisms (GMOs)-derived foods since July 2001. Therefore, we designed a multiplex PCR method to ascertain the validity of the labeling system and to monitor the status of circulation for genetically modified maize (GM Maize). Five lines of GM Maize (GA21, TC1507, Mon810, NK603, and Bt176) were used, and specific primer pairs were designed to detect each line. Using this method, the different lines of GM Maize were monitored from raw products and processed foods in Korean market. Some of the maize processed foods and raw materials were shown to contain more than one foreign gene. This method was found to be effective for-detecting five different GM Maize in a single reaction.

  • This study analyzed consumers' willingness to pay for price increases to avoid the purchase of GM foods by the expansion of GMO labeling. The subjects were asked about their knowledge of GM, concerns of potential hazards, and sources of obtained GM information. The logit model was employed and marginal effects were calculated to interpret the results. The results showed that consumers who perceived the safety of GM technology were less likely to pay for price increases, while consumers who had concerns about GM foods were more likely to pay. In addition, the study demonstrated that consumers residing in urban areas and with low levels of education and income were also less likely to pay for price increases.

  • 'New Breeding Techniques (NBTs)' have been one of hot issues, since their future will be affected profoundly by national as well as international regulatory landscapes. In this review, we compare characteristics of NBTs with conventional and genetic modification, and analyze genetically modified organism (GMO) regulatory systems in the context of possible regulation of NBTs. NBTs are very heterogeneous in terms of principles, methodologies, and final products. As Living Modified Organisms (LMO) is defined in the Cartagena Protocol on Biosafety (CPB) as an organism containing novel combination of genetic materials obtained by the use of modern biotechnology, CPB as well as other national legislations locate itself somewhere in the middle between product-based and process-based regulations. It is also noted that jurisdictions with regulatory systems more oriented to product-based one tend to be more productive and decide or may decide to exempt site-directed nucleases-1 from GMO regulation. In this context, Korean legislations are reviewed to clarify the commons and differences in GMO definitions. Act on Transboundary Movement of LMO Act, Food Sanitation Act and Agricultural and Fishery Products Quality Control Act are three major acts to regulate GMOs. It is noted that there are differences in the definition of LMO or GM food/products especially between the LMO Act and the Food Sanitation Act. Such differences may cause conflicts between Acts when policy-decision regarding the regulation of NBTs is made. Therefore, it is necessary to reorganize legislations before policies regarding the regulation of any techniques from biotechnology are made.

  • This paper is aim to report the core aspects of Codex guideline for organically grown food which is finalized by FAO/WHO Codex Alimentarius Commission on May 2000 in 28th session of the Codex committee on food labelling. The chapter of animal production had discussed for a long time before it was finalized in Ottawa/canada as well as use of GMO(Genetically modified organism), manure from factory farming, animal welfare, and fodder inputs consisting of at least 85% for ruminants and 80% for non-ruminants. As the guideline for Codex set out the several things which is very difficult for Asian country, Organic farmer in Korea should pay an attention to maintain/increase the fertility and biological activity by cultivation of legumes, green manures or deep-rooting plants in an appropriate multi-annual rotation programme, and incorporation in the soil of organic material from holding producing in accordance with the guidelines. Pest, diseases and weeds should be controlled by choice of appropriate varieties, appropriate rotation, mechanical cultivation, diversified ecosystems, flame weeding, animal weeding and steam sterilization. The use of plant growth hormone, GMO and manure from industrial management system are not allowed, and closed recycling system, rotation, resistant seeds again pest and disease should be practiced in organic farming. But these are not unfortunately practiced in the country. In the conclusion it was strongly suggested to enact the Basic Standard for Korean organic agriculture which contains the core principles of Codex guidelines, and to try the importation of the most advanced theory, skills and technology from leading country in organic farming.

  • This research was conducted to evaluate the safety of the herbicide-resistant rice, a genetically modified organism (GMO) developed by the Rural Development Administration by exposing it to 12 months old Sprague-Dawley rats for 8 weeks. The composition of herbicide-resistant brown rice with/without heating treatment was compared with those of conventional Ilpum brown rice with/without heating treatment to assess composition equivalence. Compositional analysis was performed to measure proximates, fiber, and minerals. The nutritional components of herbicide-resistant rice were similar to those of the nontransgenic control or were within the normal range of nontransgenic rice. Four groups of experimental male rats were fed one of the following diets for eight weeks: Ilpum brown rice (I) and its heated rice (IH) as non-GMO, and herbicide-resistant brown rice (G) and its heated rice (GH) as GMO- We checked clinical symptoms (anorexia, salivation, diarrhea, polyuria, anuria, fecal change), food intake, and water consumption every day, change of body weight once a week, and serum biochemistry and organ weights after 8 weeks of experimental feeding We did not find any significant differences in the above-mentioned items. These results suggested that genetically modified herbicide-resistant rice was compositionally equivalent to conventional Ilpum rice, and nutritional characteristics and safety of herbicide-resistant rice in old male rats treated for 8 weeks were not different from those of Ilpum rice, non-GMO.

  • Previously, we found that the transgenic rice plants over-expressing the Arabidopsis $H^+/Ca^{2+}$ antiporter CAX 1 (accession no. U57411) gene accumulated 2.7 to 7.5-fold more calcium in the T3 rice grains as compared to those of control. To examine physiological safety of the $T_3$ rice grains, the effect of the $T_3$ brown rice on change in levels of body weight and white blood cells was compared with that of the control Ilpum brown rice by feeding trial in mice. During the feeding trial for one month, there was no significant difference between two mice groups, which were fed by the $T_3$ brown rice or Ilpum brown rice. There were no detectable differences in their effects on immune functions including plaque-forming unit, peritoneal macrophage number, and NK-cell activity. In addition, biochemical analysis of the blood failed to exhibit any difference between two mice groups. Together, these results suggested that the $T_3$ brown rice, which was produced from a genetically modified organism (GMO), might be safe and possess a potential to be applicable as calcium-fortified feed or food. Long-term safety of the $T_3$ brown rice, however, remains to be elucidated.

  • This study was conducted to evaluate the safety of herbicide-resistant rice, a genetically modified organism (GMO) developed by the Rural Development Administration, in Sprague-Dawley rats. The nutrient content of herbicide-resistant polished and brown cooked rice was compared with that of conventional Ilpum polished and brown cooked rice to assess composition equivalence. Compositional analysis was performed to measure proximates, fiber, and minerals before animal feeding. Growing male rats were fed one of the following four diets for six weeks: Ilpum polished cooked rice (IP) and Ilpum brown cooked rice (IB) as a non-GMO and herbicide-resistant polished cooked rice (GP) and brown cooked rice (GB) as a GMO. We checked clinical symptoms (anorexia, salivation, diarrhea, polyuria, anuria, fecal change) every day, food intake, change of body weight twice a week, and serum biochemistry and organ weights after 6 weeks of experimental feeding among the four groups. Nutrient content of the herbicide-resistant rice was similar to that of the non-transgenic control and was within the published range observed for non-transgenic rice. We could not find any significant difference in the above-mentioned items as the index to be checked in the animals fed the GMO. These results suggest that the nutrient content of genetically modified herbicide-resistant rice is compositionally equivalent to that of conventional Ilpum rice and that growing male rats fed herbicide-resistant rice are no different from those fed Ilpum rice, non-GMO for 6 weeks.
