        서울시 경동시장 및 인근 대형마트에서 유통 중인 건조 수산물 150여 건을 시료로, ICP-MS를 이용하여 규격 미설정 중금속인 비소, 크롬, 니켈에 의한 오염도를 확인하고 그에 따른 위해도를 분석하였다. 크롬과 니켈은 검출량 및 위해도 분석 결과, 유의할 만한 결과를 확인할 수 없었다. 비소 검출량의 경우 건조어류 1.76±1.36 (0.00- 7.34), 건조연체류 3.38±2.42 (0.06-7.89), 건조해조류 1.99±1.33 (0.28-5.97), 건조갑각류 6.62±2.50 (3.30-13.57) ppm으로, 현재 건조 농산물 일부 및 한약재에서의 3 ppm 이하 규정을 간접적으로 적용했을 때, 건조갑각류는 분석에 사용된 시료 21건 모두 기준 이상으로 검출되었고, 건조연체류는 총 20건 중 50%에 해당하는 10건이 기준 이상, 건조 어류는 총 108건 중 15건(13.9%)이 기준 초과, 건조 해조류는 35건 중 6건(17.1%)의 시료가 기준을 초과 한 결과를 보였다. 시료 건수에 따른 한계에도 불구하고, 위 결과를 통해 각 품목별 및 세부 품목별 미 규격 중금속 오염에 대한 지속적인 자료 축적과 규격 설정의 필요성을 확인할 수 있었다. 비록 %PTWI 분석 결과 아직은 안전한 것으로 확인되었지만, 중금속은 여러 경로로 인체 내로 유입되며 위해도는 총합으로써 평가해야 하므로, 해양 및 수산물의 오염으로 인한 건강 위해 가능성에 대한 확인은 다각적인 연구와 검토가 필요할 것으로 판단된다.

        In recent years, consumers have become more interested in convenient lifestyles, leading to increased use of salted cabbages for preparation of kimchi. This study aimed to investigate the safety of heavy metals, pesticide residues, and foodborne pathogens in commercial salted cabbages in Seoul from August to November, 2014. The survey, which was conducted to determine whether or not salted cabbages were prepared under the highest sanitary conditions, showed that Seoulites are interested in purchasing hygienic and safe salted cabbages. The average amounts (range) of Pb and Cd found in 30 salted cabbage samples were 0.007 (0.000~0.063) mg/kg and 0.004 (0.000~0.012) mg/kg, respectively. The cabbages were analyzed for residues from 285 types of pesticides using the multiresidue method. Residues for pesticides were not detected. Major foodborne pathogens, specifically Escherichia coli, Salmonella spp., Listeria monocytogenes, Campylobacter jejuni, Staphylococcus aureus, Vibrio parahaemolyticus, Enterohemorrhagic Escherichia coli, Bacillus cereus, Clostridium perfringens and Norovirus, were also not detected.

        In order to investigate the classification and antibiotic resistance of Salmonella species 718 isolates were isolated from patient in Seoul from 1996 to 2001. The two hundred and ninety eight isolates (41.5%) were identified as Sal. Enteritidis, followed by Sal. Typhi 218 isolates (30.4%), and Sal. Typhimurium 87 isolates (12.1%). The identified Salmonella species were most resistant to tetracycline (32.7%), followed by streptomycin (28.0%), ticarcillin (18.1%) and ampicillin (12.4%). Among isolates, 34.7% of Sal. Enteritidis were resistant to tetracycline, 32.3% to streptomycin, 23.2% to ticarcillin, 13.5% to ampicillin, respectively. 13.8% of Sal. Typhi were resistant to streptomycin, 10.6% to tetracycline, respectively. 66.7% of Sal. Typhimurium were resistant to tetracycline, 42.5% to streptomycin, 28.7% to ticarcillin, 26.4% to ampicillin and 17.2% to chloramphenicol, respectively. Of 718 isolates, 324 isolates (45.1%) were resistant to 1 or more drugs and 64 isolates (19.8%) were resistant to 1 drug, 132 isolates (40.7%) were resistant to 2 drugs, 50 isolates (15.4%) were resistant to 3 drugs, 27 isolates (8.3%) to 4 drugs, 27 isolates (8.3%) to 5 drugs, 22 isolates (6.8%) to 6 drugs. The most prevalent multiple resistant pattern was tetracycline-kanamycin (35.5%), followed by tetracycline-kanamycin-ticarcillin (8.3%), and tetracycline-kanamycin-ticarcillin-ampicillin (7.4%). Antibiotic resistant rate of Sal. Typhimurium was 73.6%, followed by Sal. Enteritidis 53.7% and Sal. Typhi 19.3%. Most Sal. Enteritidis was resistant to 1 drug or 2 drugs, whereas Sal. Typhi and Sal. Typhimurium were more resistant to 5 (16.7%) or 6 drugs (26.6%). The old generation antibiotics such as ampicillin, tetracycline, and streptomycin were annually more resistant than the new generation antibiotics such as ceftriaxone, ciprofloxacin or cefoxitin.

        Staphylococcus aureus is gram positive, facultatively anaerobic, non-sporulative coccus, and positive for coagulase and DNase. The food oisoning outbrealc of Staphylococcus aureus increases in the world, and third occurnn happened in our country. Of 105 isolates (25.4%) obtained 413 fecal samples of food-poisoning suspicious patients. In those cases, the enterotoxins were detected firom a total of 45 isolates (42.9%), 9 isolates(20.0%) were A type, 33 isolates (73.3%) we H types, 2 isolates (4.4%) were G type and 1 isolate was a I type enterotoxin. Among the isolates possessing staphylococcal enterotoxins, 29 isolates had H type only(64.4%), 5 isolates had A type only and 4 isolates had both A and H type. 'Iieo isolates had G type only and 1 isolate had I type only. In the antibiotic susceptibility, 48 isolates (46%) had at least one antibiotic resistance among 105 isolates, 34 isolates (70.8%) were resistant to penicillin, 1 isolate (2.1%) to ampicillin, 3 isolates (6.3%) to erythromycin and kanamycin. Seven were resistant to more than two antibiotics and especially 1 isolate was resistant to penicillin-ampicillin-nitrofurantoin.
