The purpose of this study was to examine the status of environmentally-friendly ingredients and dietitians' perceptions toward them in order to find for improvement. Data was collected from questionnaires completed by 202 school dietitians and nutrition teachers in Chungbuk, and this data was analyzed utilizing the SPSS 20.0 program. The results obtained from this study were as follows: 'mixed grains (58.9%)' and 'eggs (36.6%)' were found to be the most used environmentally-friendly ingredients. 81.7% of the respondents said they 'never used' marine products, whereas 'fruits (43.6%)', 'pork (40.8%)', and 'fish (54.5%)' were the most preferred ingredients. Dietitians and nutrition teachers used environmentally-friendly marine products less than other ingredients, had a poor understanding about environmentally-friendly marine products, and demonstrated low reliability and belief in the necessity of the system. In order to verify the environmentally-friendly status of the ingredients, marks on the product and documents of certification were mostly used. In order to improve the supply system, a more strict tracking system in the distribution process by securing more reliable suppliers is required.

In order to survey residual characteristics of pesticides in the agricultural products selling at markets and to assess their safety, a total of 120 agricultural products were collected from the wholesale and traditional markets in Cheongju and analyzed the pesticide residues in them by multiresidue analysis method using GLC, HPLC and GC-MSD. Three pesticides, procymidone, penconazole, and tetraconazole, were detected from 4 samples such as onion, leek, tomato, and green pepper. Fungicide penconazole was detected from the onion collected from wholesale market. Fungicide procymidone was detected from leek and tomato and fungicide tetraconazole was detected from green pepper. Pesticide residues were detected from 3.3% of the total samples. The estimated daily intakes (EDIs) of the pesticides detected were less than 0.1% of their acceptable daily intakes (ADIs), representing that residue levels of the pesticides detected were evaluated as safe.

The aim of this study was to investigate pesticide residues in 2,877 market vegetables in the northern area of Seoul in 2013. Pesticide residues in the samples were analysed by multiresidue method for 285 pesticides using GC-ECD/NPD and HPLC-DAD/FLD. 385 samples(13.4%) were detected with pesticide residues at or below MRL, and 15 samples(0.5%) were found to detect pesticide residues exceeding MRL. The most frequently detected samples were sedum(63.6%), chamnamul(45.8%), leek(44.5%) and green&red pepper(30.8%). Among the 15 violated samples, leek(5 cases) and welsh onion(4 cases) showed the highest violation rate. A total of 74 samples(18.5%) contained multiple pesticide residues in one vegetable. Procymidone, chlorofenapyr and cypermethrin were the pesticide most frequently found. As a tool of risk assessment through the consumption of pesticide detectable agricultural products, the ratio of estimated daily intake (EDI) to acceptable daily intake (ADI) was calculated into the range of 1.05~28.61%. The results have meant that there was no health risk through dieting commercial agricultural products detected with pesticide residues.

This study was conducted to monitor 284 pesticides residue level in 2,914 commercial agricultural products in the northern area of Seoul in 2011 by the multi class pesticide multiresidue analysis methods in Korea Food Code using GC, HPLC, GC-MSD and, LC-MSD. The detection rate of pesticide residues were 14.8% (431/2,914). The order of agricultural products in which the pesticide residues were detected was perilla leaves 40.0% (28/70), chamnamul 35.5% (11/31), amaranth 30.0% (3/10) and spinach 27.7% (38/137) etc. The percentage of products that exceeded the MRLs (maximum residue limits) were 1.0% (31/431). Those products that exceeded MRLs were ginseng (6), perilla leaves (4), leek (4), welsh onion (3) and sedeum (3) etc. The 59 kinds of the pesticides were detected on this study, 21 pesticides of them were detected over MRLs. Detection rate of fungicides (56.4%) was higher than that of insecticides (42.1%). And procymidone was detected with considerable high frequency. Additionally, residual residual violates pesticides were in the order of tolclofos-methyl, endosulfan, dimethomorph, diniconazole and fludioxonil. According to the agricultural marketing channels, detection and excess rate of them were monitored. Detection and excess rate of samples circulated in agricultural traditional market were highest. The estimated daily intakes (EDI) of the pesticides were compared to personal acceptable daily intakes (PADI) in order to risk assessment by food consumption. Diazinon in Korean cabbage showed the highest %ADI, 2.9901 and others showed below 3.0 %ADI. Overall, these results indicate that residue levels of pesticides detected were evaluated as safe.

The purpose of this study was to identify the sanitation management items of school foodservice suppliers that require improvement, by assessing their sanitation practices with food commodities. Our field assessment was performed using a total of 20 vendors supplying agricultural products, meat products, seafoods and processed products; all were located in the Seoul and Gyeonggi areas. The assessment tool for sanitation management was composed of 93 checklist items and was used to evaluate seven different categories; the facility and environment, management of the facility and equipment, food materials management, process control, water management, personal hygiene management, and laboratory instrument management. A score of two was given for "satisfactory", one for "fair", and zero for "unsatisfactory". The overall average supplier score was 1.7/2.0 (85.8%). The score of the seafood vendors was highest at 1.9 (95.4%), while the lowest score of 1.3 (65.7%) occurred with the processed product suppliers. Among the sanitation management categories, water management was scored at 2.0, while inspection management was lowest at 1.4. The subcategories indicating needed improvements for the processed product suppliers were raw materials, storage, transport and recall. For the agricultural product suppliers it was preparation management. furthermore, one item within the laboratory instrument management category was unsatisfactory for both the agricultural and processed product suppliers. In conclusion, these results can be used to develop sanitation management procedures for suppliers, as well as by administration agencies to evaluate and guide those suppliers.

In this study we investigated pesticide residues on herbs and spices disrtibuted in the Incheon Metropolitan area. A total of 112 samples were purchased from off-line and on-line markets from January to October 2020. In accordance with the implementation of the Positive List System (PLS), the proper usage of pesticides is now being enforced. It is assumed that unregistered pesticides are being used on herbs and spices due to the low number of registered pesticides in the agricultural industry. Pesticide residue levels were not detected in 99 samples but 11 kinds of pesticides in 6 samples (13 times) exceeded the MRLs. The pesticides that were used in accordance with the PLS were Diazinon, Diethofencarb and Pyridalyl. However, unregistered pesticides were on the herbs and spices. Therefore, it is necessary to educate producers of herbs and spices on the appropriate use of pesticides. It is also necessary to establish MRLs on herbs and spices.

우리 전통술산업의 육성은 원료농산물의 소비증대와 수입주류의 대체, 전통문화의 복원 등 다양한 의미를 가지고 있다. 즉 쌀과 잡곡, 과일, 약초 등 우리 농산물로 빛은 민속주의 재현을 통해 개방여파로 인해 남아도는 우리 농산물의 소비증대와 국민들의 건강 증진, 전통문화의 계승발전에도 기여할 수 있기 때문에 산업적 활성화의 필요성이 크다. 특히 술은 지역축제나 관광, 예술 등과 결합한 고부가가치 문화상품이 될 수 있는 만큼 그린투어리즘(green tourism)이나 농촌문화관광을 풍요롭게 하는 중요한 컨텐츠가 될 수 있을 것으로 기대된다. 우리술산업의 활성화를 위한 정책과제로는 다음을 제시할 수 있다. (1) 우리술의 맛과 향, 숙취제거 등 품질을 개선하되 특히, 젊은층과 서민들의 기호에 맞으면서도 건강기능성을 가미한 다양한 제품의 개발과 포장 및 디자인의 개선이 필요하며 이를 위해 전문연구기관을 설립하거나 한국식품개발연구원을 통한 연구개 발과 교육 훈련이 선행되어야 한다. (2) 우리술의 품질관리와 차별적 유통을 위한 브랜드화가 필요한데 이는 지방자치단체와 관련업체에서 지역에서 생산되는 술에 대해 원료나 제조방법, 생산지역 등 품질기준과 표기방법을 제도화하고, 이를 소비자들에게 알리는 방법을 강구해야 한다 (3) 시음회나 품평회, 우리술페스티벌 등 다양한 이벤트행사를 통해 우리술에 대한 부정적 이미지를 개선하고 소비를 촉진하기 위해서는 적극적인 홍보와 판매촉진이 필요하다. (4) 우리 전통술의 품질향상과 가격인하를 위해 시설현대화와 기술개발, 포장 및 디자인개선, 원료구입, 홍보 및 판매촉진 등에 소요되는 자금을 지원하고 주세 차등화 등 조세감면과 경영컨설팅 등의 지원이 필요하다. (5) 현재 국회에 계류 중인 [전통술산업육성 및 지원법(안)]를 통과시켜 제도를 정비하고, 여러 부처에 흩어져 방치되고 있는 농민주 및 민속주 관련 행정체계를 정비해야 한다.
