  • BACKGROUND: Food Sanitary Act establishes Maximum Residue Limits (MRLs) of pesticides in food that are newly registered and used per each quarter, as stipulated by Agro-chemical Control Act. Current Food Code contains the MRLs for a total of 418 pesticides in 184 food types. METHODS AND RESULTS: National MRLs for pesticides have been established by based on scientific data of good agricultural practice, acceptable daily intake (ADI), food intake, average body weight and others. MRLs for pesticides are generally set under the principle that theoretical maximum daily intake (TMDI) are always below ADI. As results, 27 MRLs in agricultural products were newly proposed for 22 pesticides (fungicide: azoxystrobin, fludioxonil, fluquinconazole, flusilazole, iprovalicarb, kresoxim-methyl, mandipropamid, metconazole, pyraclostrobin, tebuconazole, triflumizole, etc., Insecticide: dinotefuran, flubendiamide, indoxacarb, cyhalothrin, spinetoram, thiacloprid, thiamethoxam, metaflumizone, etc., Acaricide(miticide): cyenopyrafen, lufenuron) in 2010. CONCLUSION(s): There is no intake concerns for establishment of pesticide MRLs on foods in this time. Because the ratio of theoretical maximum daily intake (TMDI) are set below that of ADI.

  • Herein, we present the results of our investigation of 61 pesticide residues in 100 samples of green teas obtained from Korean markets. Bifenthrin, chlorpyrifos, dicofol, EPN, chlorfenapyr, tebuconazole, cyhalothrin, difenoconazole, and tebufenpyrad were detected in 22 of the 100 green tea samples. The quantity of pesticide residues for bifenthrin was 0.12 ppm (maximum residue limits (MRLs): 0.3 ppm) in one sample, chlorpyrifos was 0.24-0.78 ppm (MRLs: 2.0 ppm) in three samples, dicofol was 1.64-4.19 ppm (MRLs: 50.0 ppm) in two samples, EPN was 0.13 ppm (MRLs: 0.05 ppm) in one sample, chlorfenapyr was 0.01-1.23 ppm (MRLs: 3.0 ppm) in 16 samples, tebuconazole was 0.71 ppm (MRLs: 5.0 ppm) in one sample, cyhalothrin was 0.05-0.3 ppm (MRLs: 2.0 ppm) in five samples, difenoconazole was 0.23 ppm (MRLs: 2.0 ppm) in one sample, and tebufenpyrad was 0.06-0.07 ppm (MRLs: 2.0 ppm) in two samples. More than two pesticide residues were detected in seven samples. All detected pesticide residues (with the exception of EPN) were within the MRLs.

  • Through the five years analysis of monitoring data on pesticide residues from 1998 to 2002, current status on pesticide residues on commercial agricultural products in Seoul area was evaluated. The rate of over maximum residue limits(MRLs) has been decreased into 5.8% in 1998, 2.5% in 1999, 1.6% in 2000, 1.4% in 2001, and 1.5% in 2002 gradually, where as total sample numbers analyzed increased 1,300 in 1998, 4,200 in 1999, 5740 in 2000, 6,160 in 2001, and 5,440 in 2002 annually, The pesticide which frequently detected in samples were endosulfan, procymidone, chlorotalonil, vinclozolin, and chlorpyriphos and pesticide found over MRLs were procymidone, vinclozolin, endosulfan and etc.

  • This study was conducted to monitor the current status of pesticide residues in agricultural products before auction at whole markets in Busan area from March 2006 to December 2008. Of the 7,237 samples that were analyzed by multiresidue methods, 1,164 samples (16.1%) had pesticide residues and 231 samples (3.2%) exceeded the maximum residue limits (MRLs). 181 samples of the 231 samples exceeding MRLs were applied to the tentative limits because the use of the pesticides for the agricultural products was not established against the MRLs in the Korea Food Code, and it is equivalent to 78.4%. The order of pesticides exceeding MRLs was endosulfan, procymidone, chlorothalonil, ethoprophos, chlorpyrifos, diethofencarb, kresoxim-methyl and EPN. Of 211 samples with two or more pesticides residues, the residues exceeded the MRLs in 80 samples and it is equivalent to 37.9%. This study results suggested that pesticide residues exceeding MRLs could be attributed to the use of inapplicable pesticides for agricultural products and the use of two or more pesticides.

  • Korean maximum residue limits (MRLs) for pesticides have been established based on scientific data of good agricultural practice, acceptable daily intake (ADI), food intake, average body weight and others. MRLs for pesticides are generally set under the principle that theoretical maximum daily intake (TMDI) are always below ADI. As results, 104 MRLs are going to be newly established for 24 pesticides and 102 MRLs are going to be added for 63 pesticides that have regulation already, Among new pesticides, ethaboxam and flupyrazofos are effective components that are first developed in Korea. In case of dithiocarbamates, MRLs are classified by 3 groups such as dimethyldithiocarbamates, ethylenebis (dithiocarbamate)s and propineb.

  • 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.

  • This study was carried out to investigate the current status of pesticide residues in 3,735 agricultural products in the northern area of Seoul from January to December in 2008. 3,735 samples, comprising 119 types of agricultrural products were assessed via a multiresidue method to detect 260 pesticides. Pesticide residues were detected in 19.7% (737 of 3,735 samples), and the rate at which the detected residues violated the maximum residue levels(MRLs) of the Korean Food Code was 3.2% (121 of 3,735 samples). Pesticide residues were detected in 72 spin-aches, 64 peppers, 45 sweet peppers, 40 perilla leaves, 38 korean cabbages and 37 dried agricultural products. The samples that violated the MRLs included 14 perilla leaves, 13 spinaches, 12 leek, 6 lettuces(leaf), 6 chards and 6 gyeojchaes. Procymidone, endosulfan, chlorfenapyr, cypermethrin, bifenthrin, tebuconazole and fenvalerate were all frequently observed. Procymidone, endosulfan, dimethomorph and diniconazole were the pesticides most frequently detected at levels that violated the Korean Food Code MRLs.

  • A study of the tissue depletion of florfenicol (FFC) administered orally to pigs at a dose of 0.05 kg/ton feed for 7 days was performed. Sixteen healthy cross swine were administered with FFC. Four treated animals were arbitrarily selected to be sacrificed 1, 3 and 5 days after the end of treatment. FFC residue concentrations in muscle, liver, kidney, and fat were determined using high-performance liquid chromatography (HPLC) with ultraviolet photometric detector at 230 nm. The correlation coefficient ($R^2$) of the calibration curve for florfenicol amine (FFCa) was > 0.997 and the limits of detection and quantification were 0.012 and $0.040{\mu}g/mL$, respectively. Recovery rates in swine edible tissues ranged from 79.1 to 93.5%. In the FFC-treated group, FFC residues at 3 days post-treatment were below the maximum residue limits (MRLs) in muscle, kidney and fat, and those at 5 days post-administration were below the MRLs in all edible tissues. These results suggest that the withdrawal period of FFC after the drug treatment might be 5 days, which is a sufficient amount of time for reduction of the FFC residues below the MRLs in all edible tissues.
