  • Consumer protection and prevention of foodborne diseases are essential elements of food safety program for every country The food safety program proposed by WHO was introduced and the importance of GAP in establishing residue limits of intentional additives in food production was emphasized. The procedures and differences in establishing maximum residue limits of pesticides on food crops by Codex Alimentarius Commission and Korea were explained. Finally, considerations in harmonization of Korean standards with Codex MRLs were suggested.

  • We developed an alternative assay method without hazardous reagent of chloroform for urazamide tablets in Korean Pharmaceutical Codex. The HPLC analytical method was validated by system suitability, linearity, precision, accuracy and robustness. The linearity of the calibration curves in the desired concentration range is good ($r^2$ >0.999). Precision was obtained less than RSD 1.17%. Accuracy was obtained with recoveries in range of 98.12% and 99.47%. The developed assay could be expected to become valuable tools for revising the Korean Pharmaceutical Codex.

  • The object of this study is to compare the performance of the 3M Molecular Detection Assay 2 (3M MDA 2) and the Korea Standard Food Codex (KSFC) Method (i.e., isolation media and real-time PCR) in detecting Salmonella Typhimurium and Listeria monocytogenes in traditional Korean foods. Yuk-hwe and Yuk-sashimi (types of raw beef dishes) were artificially inoculated with $10^0-10^4CFU/25g$ of L. monocytogenes and S. Typhimurium. Citrobacter freundii and Listeria innocua were used as competitive microflora. After enrichment, the samples were analyzed using 3M MDA 2 and real-time PCR. All samples inoculated at concentrations of $10^0-10^4CFU/25g$ without competitive microflora were positive for S. Typhimurium and L. monocytogenes, as detected by 3M MDA 2 and Korea Standard Food Codex (KFSC) Method. In addition, part of the samples were positive for the presence of C. freundii and L. innocua. The 3M MDA 2 - Salmonella and Korea Standard Food Codex (KFSC) Method showed similar detection performances in Yuk-hwe and Yuk-sashimi. The 3M MDA 2 method for Salmonella and Listeria, which is a LAMP-based technology, can be used for rapid detection of S. Typhimurium and L. monocytogenes in raw beef. LAMP bioluminescence assays provide results on the subsequent day and are simple to use compared with the Korea Standard Food Codex (KFSC) Method, particularly in terms of DNA preparation.
