  • Veterinary drugs have been used to prevent livestock diseases for many years. In spite of having advantages, sometimes indiscriminate application, overdose and abuse may cause risk for human. Therefore, management and risk assessment of veterinary drugs become essential to ensure food safety. So the National Veterinary Research & Quarantine Service (NVRQS) impose on registration for use of veterinary drugs also Korea Food and Drug Administration (KFDA) fixed the maximum residue limits (MRLs) for veterinary drugs in food. Basically, KFDA set MRLs based on the veterinary drugs residual data. Moreover, KFDA estimates the theoretical maximum daily intake (TMDI) with food consumption data and population mean body weight. Recently, 116 veterinary drug MRLs including banned veterinary drugs have been established and other 32 veterinary drugs MRLs will be established within 2009. In 2010, MRLs among antibiotics and synthetic antibacterial agents in livestock fishery products (including milk and eggs) and honey (including royal jelly and propolis) which have not been set in Korea Food Code and Codex Alimentarius Commission (CAC) will be regulated as uniform limit (0.03 mg/kg). In future, veterinary drugs will be controlled strictly to strengthen public health by improving analytical method.

  • It is difficult for consumers to satisfy high safety request with post-management method such as inspection and surveillance, as various changes in-and-out of the country associated with food safety. In terms of food safety problems related to foods, it is crucial to recognize public health and consumer protection and construct pre-preventive Food Control System. A joint committee, FAO/WHO made the following consultations to the National Food Safety System. ${\circ}$ Approach entirely from farm to table ${\circ}$ Get ready for Risk Analysis System ${\circ}$ Secure transparency ${\circ}$ Establish the optimal policy by evaluating the effect of regulation When it comes to summarizing the consultation, it would be accumulated as two key words; "Efficiency" and "Credibility". Whereas the problem of efficiency focuses on precaution rather than post-management, it requires policy option to maximize consumer's benefit by evaluating the cost for the Food Safety Management and its benefit. Also, analyzing risk's character and amount, demanding an optimal means, and introducing scientific analysis system put much value on the stakeholder's communications are procedure's security which can satisfy both "Efficiency" and "Credibility" simultaneously. Especially, it is emphasized here that Risk Assessment need to be separated from Risk Management. This action is a valid means of credibility security throughout improving transparency. A number of nations and organizations have reformed the method of food management passing through reflection and examination of the prior National Food Safety Management since BSE occurred in Britain, 1996. FSA; Food Standard Agency, AFFSA, EFSA, BfR, and FSC are Risk Assessment Organization functionally separated from Risk Management Organization, JECFA, JMCFA, JMPR, JEMRA in Codex charge Risk Assessment internationally. In case of advanced countries excluding several those such as The U.S. and so forth, though these Risk Assessment Organizations are either separated functionally within Risk Management Organization or operated as apart organ, common factors are in which it has independence as Science Base. While securing independence of Risk Assessment Function, it is a tendency Risk Management should be functionally unified into efficiency as well. Though Germany constructs integral Risk Management System of diverse ways according to social and political conditions of each country such as GFOCP, DVFA, SNFA, CFIS and AQIS, there is a key word in the center, "Securing efficiency of Food Safety Management". However our nation has a representative plural;diversified system with The U.S., we took a step forward for unification as empowering policy's generalization;adjustment and Risk Assessment Function by means of enacting the "Food Safety Fundamental Law" in 2008 and establishing the "Food Safety Policy Commission" with private and governmental sectors in the Prime Minister's office. Even though the unification of Risk Management hereby increased, there is the lack of strengthening function of Risk Assessment and securing independence. It needs to be required for the professional committee in Food Safety Policy Commission to develop as a exclusive office of Risk Assessment by separating from a policy decision. Administrative Branches should reinforce feeble functions such as fundamental investigation;research for carrying out Risk Assessment with securing efficiency throughout reassessment of prior Risk Management Means.

  • The dropwort was fermented by steeping with brown sugar, fructose syrup or oligosaccharide at room temperature for 2 month, and then stored at cold room for 6 months. The dropwort extracts prepared with three different sugars showed more than $50^{\circ}$Brix, below pH 4.0 and about $0.7\%$ titratable acidity. The dropwort extract with brown sugar showed $1.6{\times}10^6$ viable cell counts and $21.2\%$ reducing sugar. Formation of $CO_2$ gas was superior to the dropwort fermented with brown sugar or oligosaccharide. The dropwort extract with fructose syrup indicated $9.0{\times}10^3$ viable cell counts and $50.1\%$ reducing sugar. Microorganism present in fermented dropwort extract was effectively pasteurized by the addition of $3\%$ citric acid and heat-treatment at $85^{\circ}C$ for 15 min, resulting in the less production of $CO_2$ gas. The dropwort extracts prepared with brownsugar, fructose syrup or oligosaccharide was suitable for the standardization that required for plant extract in Korea Food Codex.

  • To determine the amount of total bromide as 2-bromoethanol, the domestic agricultural products such as rice, barley, carrot, cucumber, apple, tomato, squash, green pepper, melon, strawberry, grape, peach, potato and celery were analyzed by GC/MSD as well as GC/ECD. The bromide was detected in most of the domestic samples and the highest bromide residue determined was 13.2 ppm in barley. The imported agricultural products including melon, kiwi, lemon, pineapple, banana, orange and grape were also analyzed for the bromide. The bromide was also detected in most of the imported ones and the highest bromide residue determined was 12.3 ppm in pineapple. In addition, the bromide residue in instant noodle spices was monitored for 4 years, recently. As results, in 1994, the bromide content was in the range of non-detection to 2.4 ppm (average 1.1 ppm) from 22 out of 24 samples; in 1995, the bromide content was 1.0 and 2.2 ppm from 2 out of 37 samples; in 1996, the bromide content was in the range of 0.7 to 37 ppm (average 12.4 ppm) from all 11 samples; and in 1997, the bromide content was in the range of 0.2 to 4.6 ppm (average 1.2 ppm) from all 59 samples. However, none of sample analyzed for the bromide was exceeded Maximum Residue Limit(s) of Korea and Codex in these survey.

  • 국제기준(Codex)에 부합하는 유기농산물의 생산을 위해서는 저항성 품종의 유기종자 사용을 원칙으로 규정하고 있으나, 현재까지 우리나라의 경우는 찰옥수수 등 주요 식량작물에 대한 유기채종기술이 거의 전무한 실정이다. 본 연구는 찰옥수수 유기채종기술 확립을 위한 기초 자료로 이용하고자 찰옥수수 유기 채종에 따른 파종기별 생육 및 수량특성에 대하여 검토하였다. 유기종자 생산을 위한 채종시험은 홍천군 남면에 위치한 농가 유기포장에서 수행되었으며, 시험품종은 옥수수시험장에서 육성 보급되고 있는 미백2호 및 미흑찰 원종종자를 이용하였다. 파종기는 4월 16일, 5월 4일, 5월 27일 등 3처리로 구분하여 모 부본 동시파종 하였다. 재식밀도는 80${\times}$25cm로 하여 점파하였고 모 부본의 재식비율은 2:1로 웅주간파 하였다. 잡초방제는 흑색 P.E. Film으로 멀칭 재배하였고, 유기질비료는 H사에서 생산된 혼합유박비료를 전량 기비로 시용하였다. 파종기별 출사일수는 미백2호의 경우 4월 파종에서 79일로 가장 길었고, 파종 시기가 늦을수록 출사일수는 짧아지는 경향을 보였다. 미흑찰의 경우에는 미백2호의 결과와 같은 경향으로 파종시기가 늦을수록 출사일수가 빨라지는 경향을 보였으며, 간장 및 착수고 또한 미백2호와 미흑찰 모두 4월 파종에서 가장 높았고, 파종기가 늦을수록 낮아지는 경향이었다. 이삭특성에 있어서 이삭장과 착립장은 미백2호 및 미흑찰 모두 4월 중순 및 5월 상순 파종간에 큰 차이가 없었으나, 5월 하순 파종에서 현저하게 짧아지는 경향을 보였다. 발아율의 경우 미백2호는 4월 중순 및 5월 상순 파종에서, 미흑찰은 5월 상순 파종에서 높게 나타났다. 종실중과 100립중은 미백2호 및 미흑찰 모두 4월 중순과 5월 상순 파종간에 큰 차이가 없었고, 5월 하순 파종에서 현저하게 감소하였다. 10a당 채종수량은 미백2호의 경우 4월 상순 파종에서 217㎏으로 가장 높았고, 미흑찰은 5월 상순 파종에서 164kg/10a으로 가장 많았으며, 두 품종 모두 5월 하순 파종에서 채종수량의 뚜렷한 감소가 나타났다. 따라서 찰옥수수 유기종자의 안정적 채종과 정상수량 확보를 위해서 미백2호는 4월 중순 파종시에 그리고 미흑찰은 5월 상순 파종시에 채종 안전성이 가장 우수한 것으로 판단되었고, 또한 채종수량에 직접적으로 영향을 미치는 1개 이삭당 종실중과 100립중도 크게 증가하는 것으로 나타났다.

  • Residual materials such as veterinary drugs, environmental contaminants, and pesticides are affecting food safety. High resolution techniques and quality controls are needed to analyze these materials from part per million to part per trillion quantities in food. In order to achieve quality results, standardized methods and techniques are required. Our laboratories were prepared to obtain a certificate of accreditation for ISO/IEC 17025 in the analytical criteria of animal drugs, dioxins, pesticides, and heavy metals. ISO together with IEC has built a strategic partnership with the World Trade Organization with the common goal of promoting a free and fair global trading system. ISO collaborates with the United Nations Organization and its specialized agencies and commissions, particularly those involved in the harmonization of regulations and public policies including the World Health Organization and CODEX Alimentarius for food safety measurement, management and traceability. Our goal was to have high quality analysts, proper analytical methods, good laboratory facilities, and safety systems within guidelines of ISO/IEC 17025. All staff members took requirement exams. We applied proficiency tests in the analysis of veterinary drugs (nitrofuran metabolites, sulfonamide and tetracyclines), dioxins, organophosphorus pesticides, and heavy metals (Cd, Pb, As) to the Food Analysis Performance Assessment Scheme (FAPAS) at Central Science Laboratory, Department for Environment Food and Rural Affairs (DEFRA), England. The results were very satisfactory. All documents were prepared, including system management, laboratory management, standard operational procedures for testing, reporting, and more. The criteria encompassed the requirements of ISO/IEC 17025:1999. Finally, the Korea Laboratory Accreditation Scheme (KOLAS) accredited our testing laboratories in accordance with the provisions of Article 23 of the National Standards Act. The accreditation will give us the benefit of becoming a regional reference laboratory in Asia.

  • Analytical method for determination of florfenicol was developed for estimate veterinary drug residue of unestablished MRLs in meat. The method was validated in correspondence with the CODEX guideline for florfenicol residue in meat. The samples mixed with sodium sulfate were extracted with ethyl acetate. After clean-up, the residue was dissolved in mobile phase and analyzed using high-performance liquid chromatography with fluorescence detector. The calibration curve showed good linearity($r^2=0.9997$) within the concentration range of $0.05{\sim}1.0\;mg/kg$. The limit of detection(LOD) and limit of quantification(LOQ) were validated at 0.012 and 0.039 mg/kg, respectively. The recoveries in fortified meat ranged from 85.6 to 95.6%($1.1{\sim}5.3%$ RSD) at the 0.05 to 0.4 spiking levels. We monitored 150 samples of meats that were purchased in Korea(Seoul, Busan, Daegu, Daejeon and Gwangju). Among tested samples, florfenicol was detected in 1 of pig at the level of 0.040 mg/kg, and below LOQ in 1 of cattle, 2 of pig and 2 of chicken. The residues of florfenicol in the tested samples were within the MRLs.

  • An analytical method for the simultaneous determination of nine quinolones (QNs) namely, marbofloxacin, norfloxacin(IS), ciprofloxacin, danofloxacin, enrofloxacin, sarafloxacin, difloxacin, oxolinic acid, and flumequine in flatfish and egg was developed and validated using liquid chromatography with fluorescence detection (LC-FD). The samples were extracted using a traditional liquid-liquid extraction process; deproteinization was accomplished by the addition of trichloroacetic acid and acetonitrile (ACN), and defatting was performed with hexane. Chromatographic separation was achieved on a reverse phase C8 column with gradient elution using a mobile phase of 200 mM ammonium acetate buffer (pH 4.5) and ACN. The proposed method was validated according to the CODEX guideline. Mean recoveries of QNs from flatfish and egg were 89.6-106.5% with relative standard deviations (RSDs) below 15% at three different concentrations of 50, 100 and $500{\mu}g/kg$. Linearity was obtained with a correlation coefficient ($r^2$) of 0.9989-1.0000. The LOD for the investigated QNs was $1-16{\mu}g/kg$ depending on flatfish and egg. The present method can be applied simultaneously to determine QNs in muscle of flatfish and egg.
