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.

This study was practiced to survey food-borne bacterial aspects of Escherichia coli and Bacillus cereus etc. from 210 processed seasoned marine products in Garak fishery wholesale market in Seoul, 2009. Distributions of these bacterial isolates were 28 coliforms, 32 Bacillus spp., 71 Staphylococcus spp., 11 Listeria spp, and 10Enterococcus spp. in 157 dried squids, 23 dried file fishes, and 20 dried pollacks etc. respectively. Results in 16 kinds of antibiotics susceptibility test by disc diffusion method, special multiple drugs resistance patterns were NOR + LVX + CIP + SAM+ VA + S + TE + CF, SAM + C + VA, VA + S + TE, and VA + S in 9 E. coli strains, also,AMC + SAM + CF, SAM + CF, and VA + CF in 21 Bacillus cereus strains respectively. On the basis of the results above, many seasoned dried fishes had multiple drugs resistances, conclusively, we suggest limited guideline and special management on use of antibiotics in floating net cages of fishery farms.

This study was performed to investigate the contents of sulfites in 2,770 dried marine products in Seoul Chung-Bu market from March to October in 1999. Sulfites of the samples were determined by Zn powder reduction method and Monnier-Williams's modified method. Eight samples of 2,770 (0.29%) were detected over 30ppm in S02 contents by Monnier-Williams's modified method. In samples detected over 30ppm, six dried filefishes(130.2-573.4ppm) were imported from Vietnam, same kind of other one(114.2ppm) was from China and the other one Alaska pollack(195.3ppm) was domestic. By Zn powder reduction method, 259 dried marine products (259/2,770=9.35%) were positive reaction (1-30ppm). These were 93 dried shrimps, 53 filefish meats, 34 dried squids, 33 slices of dried pollacks and 17 sea mussel meats. So sulfites must be use commonly to prevent black spot and preserve for many dried shrimps, filefishes meats, dried squids etc. According to results, the quality test for the imported dried marine products must be reinforced to supply safety food for the citizens.
