Abstract

The potential risk of heavy metals and residual pesticides in imported sawdust media inoculated with oak mushroom cultures is a concern for safe mushroom production in Korea. To obtain preliminary data for a sound analysis of this risk, this study was undertaken to analyze the presence of heavy metals and residual pesticides in the oak mushroom media imported from six different regions in China, between 2013 and 2015. Lead, arsenic, chrome, mercury, and cadmium were analyzed; arsenic, chrome, and mercury were not detected. Lead was detected in the imported oak mushroom media from Jinlin, Shandong, Liaoning, and Tianjin. The detection level of lead ranged from 1.7 to 3.2 mg/kg. Cadmium was detected at a level of 0.028 to 0.037 mg/kg in the media from Shandong and Liaoning. No residual pesticides were detected in any of the samples.

국내 안전 버섯생산을 위해서 수입된 표고균이 접종된 표고배지에서 중금속과 잔류농약의 존재 위험성을 두고 우려가 있어 왔다. 버섯의 안전 생산을 위해서는 우려되는 위험성에 대해 건전한 논의를 위한 기초 자료가 필요하다. 이에따라 본 연구에서는 2013년과 2015년 사이 중국 6개 지역에서 수입된 표고균이 접종된 톱밥배지에서 중금속과 잔류농약 존재여부를 알고자 분석을 수행하였다. 납, 비소, 크롬, 수은, 카드뮴 중에서 비소, 크롬, 수은은 검출되지 않았다. 납은 길림, 산동, 텐진, 요녕 지역에서 수입된 표고톱밥배지에서 검출되었으며 검출수준은 1.7 에서 3.2 mg/kg 이었다. 카드뮴은 산동과 요녕 지역에서 검출되었고 검출수준은 0.028 to 0.037 mg/kg 이었다. 잔류농약은 모든 시료에서 불검출되었다.
