The strains of Salmonella othmarschen and Norovirus isolated from outbreak A, the funeral ceremonies incidents in Ouri-shi of Oyeonggido in, 2007, were subjected to genotyping by using PFGE and extraction of RNA by using RT-PCR. 24 Salmonella othmarschen were isolated from 37 cases (patients 12 cases, cookers 4 cases, foods 7cases, knife, kitchen board, dish towel 4 cases, etc) and PFGE patterns showed that 22 strains isolated from the same incident were almost of the same pattern and 2 strains exhibited 50% of the pattern. Antimicrobial susceptibility patterns were such that there were 22 case susceptibility patterns and 2 case resistance patterns (strain 4: AM, CF, CIP, NA, TE TIC and strain 13: CF, CZ). Norovirus G1 (1case), Norovirus G2 (7cases), Norovirus G1,G2 (1case) were detected by using RT-PCR. The fine typing ability and reliability of PFGE and BioNumerics are helpful for establishing out the foodborne pathogens of outbreaks.

This study was performed to survey and evaluate contents of Pb and Cd in colored plastic kitchenwares by Korea Food Sanitation Act. The tested samples were 160 products(32 PE, 65 PP, 10 PS, 18 ABS and 35 MF) in a local market. The Pb and Cd contents range in the samples were ND~357.l㎎/㎏ and ND~376.6㎎/㎏. Pb contents in 6 samples(1 PE, 1 PP, 2 PS and 2 MF) and Cd contents of 2 samples(1 PE and 1 ABS) were above the legal limits. Among the illegal smples, Pb contents were 140.8㎎/㎏, 283.4㎎/㎏, 134.0㎎/㎏, 329.2㎎/㎏, 357.l㎎/㎏ and 218.3㎎/㎏, respectively and Cd contents were 123.l㎎/㎏ and 376.6㎎/㎏. Pb and Cd in various food simulants were not detected in migration test for illegal samples. Simulants were tested at 25℃ and 60℃ for n-heptane and 4% acetic acid, and 60℃ and 95℃ for water.

This study was performed to survey and evaluate the contents of plasticizers such as DEP(diethyl phthalate), DPrP(di-n-propyl phthalate), DBP(di-n-butyl phthalate), DPP(di-n-pentyl phthalate), DCHP(dicyclohexyl phthalate), BBP (butylbenzyl phthalate), DEHP (di-(2-ethylhexyl) phthalate) and DEHA(di-(2-ethylhexyl) adipate), which are suspected as endocrine disruptors, in food and drug PVC packaging. Tested samples were 5 food wraps, 35 food containers, 40 food and drug packages(type of tablet and capsule) in Gyeonggi-Do area. The contents of DEHA in wrap were 188.9g/㎏, 203.1g/㎏, 238.4g/㎏, 290.9g/㎏ and 308.3g/㎏, respectively, while the other plasticizers were not detected. DEHP was used in 4 samples of food containers and DEHP contents were 4.7g/㎏, 30.7g/㎏, 35.8g/㎏ and 53.4g/㎏, respectively. In food and drug packaging materials(type of tablet and capsule), the plasticizers were not detected.
