The purpose of this study is the establishment of scientific processes for making food safety policies. Thus, we investigated pesticide residue level of the agricultural commodities from market, and performed risk assessment. Fifteen agricultural items are chosen based on the frequency of Korean consumption. The samples were collected from 9 cities where populations are more than one million. Total 283 active ingredients were monitoring ( total sample number =232). Single-analysis of target pesticides was for three kinds of possible growth regulators and the multicomponent analysis was for 280 kinds of pesticides, a total of 283 species were selected to perform the pesticide residues. Before monitoring the analytes, the improvements of the analytical methods were done by method validations under the CODEX analytical method development guidelines and can produce metrics that represent the international standards applied in accordance with the guidelines. In addition to residual pesticides detected during monitoring we compare the ADI to EDI values using detected result and dietary consumption data which is extracted from annual market basket survey. The 163 samples were non-detected in the total 232 samples so it means that every agricultural commodity will residual pesticides-free in 70.3%. The detected residual pesticides showed for a total of 69 cases (29.7%). Two of samples violate Korean MRL (0.9%). The ratio of EDI compared to ADI resulted in only from 0.00087 to 0.902%. In result, we can assume that all detected residual pesticides are very safe level and current policies of Korean pesticides control may be working.

Microplastics with a size of less than 5 mm have emerged as an important environmental and food safety issue, as they have been detected not only in marine but also in terrestrial ecosystem and drinking water. Although many studies have been conducted on the exposure of microplastics and the effects on human health, the lack of standardized experimental methods for microplastics has been reviewed as a major problem. In order to overcome this, European countries such as the Netherlands and Germany are conducting a project to develop detection methods for microplastics as well as to establish the risk assessment methodologies for microplastics. Being the microplastics suggested to have a substantially potential risk on human health, reliable risk assessments should be conducted considering the various sources of microplastics, chemical pollutants and biological factors. In addition, international standards and regulations should be applied.

The risk ranking of food groups included the Korea Food Code is a potentially powerful means to prioritize food safety management strategies. Although the interest in risk ranking of food groups has been increasing worldwide, there was, until recently, no standard system in Korea for the risk ranking of food groups. This study was conducted to rank food groups using theoretically estimated comparative risk scores of 101 food groups included the Korea Food Code. These scores were estimated using the risk evaluation model, which focuses on 3 aspects, namely, exposure assessment, severity assessment, and consumption part. The results of this study revealed that the risk was the highest in the case of ready-to-eat (RTE) food items, followed by fish products and breads. Using this ranking system, we can identify the food with high risk scores and design risk management strategies targeted specifically at these items.

Microorganisms involved in food fermentation not only improve the aroma and taste of the food, but also enhance its preservation. Thus, they are added as starter cultures to boost the final product quality of commercial fermented foods. Although these microorganisms originate from fermented foods and have a long history of consumption, the European Union recently applied the concept of Qualified presumption of Safety (QPS), which is a safety evaluation system for microorganisms used in food or feed in Europe. The QPS system is a species-level safety system and shares results with the European Novel Food System, a strain-level safety evaluation system. In the United States, microorganisms added to fermented foods are considered as food additives or Generally Recognized as Safe substance. In Korea, food microbe lists are presented at the species level. Moreover, the nation has established a strain-oriented evaluation system that applies temporary safety evaluation methods for food raw materials as well as new raw materials. However, when it comes to microorganisms isolated from traditional fermented foods and other fermented food products, there is no definition of the term "species," and there is a lack of an evaluation system at the species level. Therefore, such an evaluation system for microbial species used in Korean fermented foods is necessary.

This study was performed in order to assess the risk of earthworm when the picoxystrobin was sprayed in Korean orchard. The acute toxicity ($LC_{50}$) of picoxystrobin active ingredient(99.3%) and soluble concentrate (25%) against earthworm was showed 10.93 mg/kg and 8-16 mg/kg respectively. This earth worm toxicity value means that the picoxystrobin do not show the earthworm risk in present Korean risk assessment system. However, in the test which was simulated the rainfall after spraying, all the earthworm were died in 24 hours. This result indicated that the risk assessment for the earthworm should be considered the weather condition.
