건조 수산가공식품의 안전성 확보를 위해 2020년 경기도 내 유통 중인 건조 수산가공식품 12품목 120건을 수거하여 방사능(131I, 134Cs, 137Cs) 및 중금속(납, 카드뮴, 비소, 수은) 함량을 분석하였다. 모든 시료에서 자연 방사성 핵종 중 하나인 40K만 검출되었으며, 인공 방사성 물질인 131I, 134Cs, 137Cs는 최소검출가능농도(MDA) 이하의 값을 나타내었다. 중금속의 평균 함량[평균±표준편차(최소값-최대값)]은 생물로 환산하였을 때 납 0.066±0.065(N.D.-0.332) mg/kg, 카드뮴 0.200±0.406(N.D.-2.941) mg/kg, 비소 3.630 ±3.170(0.371-15.007) mg/kg, 수은 0.009±0.011(0.0005-0.0621) mg/kg 이었으며, 수산물에서 중금속 기준이 있는 제품의 경우 모두 기준 규격 이내로 나타났다. 국내산 제품과 수입산 제품의 중금속 함량은, 조개의 카드뮴과 새우의 수은 함량에서만 유의적인 차이를 나타내었다(P<0.05). 본 연구 결과, 유통 중인 건조 수산가공식품에서 방사능 및 중금속은 안전한 수준인 것으로 판단되나, 식품 중 특히 수산물에서 방사능 오염에 대한 국민의 우려가 크기 때문에 국민들의 불안감 해소를 위해 방사능 검사는 지속적으로 필요할 것으로 생각된다. 또 향후 건조 수산가공식품 중에서도 건조된 형태로 직접 섭취 가능한 제품의 중금속 관리 기준 설정을 위한 기초 자료로 활용할 수 있을 것이다.

A total of 120 samples corresponding to 12 categories of dried processed fishery products distributed in Gyeonggi-do were examined for radioactivity contamination (131I, 134Cs, 137Cs) and heavy metals (lead, cadmium, arsenic, and mercury). One natural radioactive material, 40K, was detected in all products, while the artificial radioactive materials 131I, 134Cs and 137Cs were not detected at above MDA (minimum detectable activity) values. The detection ranges of heavy metals converted by biological basis were found as follows: Pb (N.D.-0.332 mg/kg), Cd (N.D.-2.941 mg/kg), As (0.371-15.007 mg/kg), Hg (0.0005-0.0621 mg/kg). Heavy metals were detected within standard levels when there was an acceptable standard, but the arsenic content was high in most products, although none of the products had a permitted level of arsenic. In the case of dried processed fishery products, there are products that are consumed by restoring moisture to its original state, but there are also many products that are consumed directly in the dry state, so it will be necessary to set permitted levels for heavy metals considering this situation in the future. In addition, Japan has decided to release contaminated water from the Fukushima nuclear power plant into the ocean, so there is high public concern about radioactivity contamination of food, including fishery products. Therefore, continuous monitoring of various food items will be necessary to ease consumers’ anxiety.
