To propose a safety control system for microbial fermented tea, eighty kinds of microbial fermented tea were collected. The residual levels of 222 kinds of pesticides and 5 kinds of heavy metal (Hg, Pb, Cd, As, Cr) in the tea were investigated with our monitoring systems. As the results, seven pesticides, such as permethrin, cyhalothrin, cypermethrin, fevnalerate, BHC, fenvalerate, and fluquinconazole, were detected at concentration in the range of 0.1~3.5 ppm in 14 kinds of the tea. In the case of the heavy metals, 0.0017~0.0665 ppm of Hg, 0.0004∼1.3856 ppm of Pb, 0.0004~0.0287 ppm of Cd, and trace~0.6910 ppm of As were detected, which were below the CODEX standard. The establishment of a safety standard for Cr is necessary, because there is no maximum residual level (MRL) for it, although this heavy metal showed a higher residual amount (trace~3.5917 ppm) than the others in this study.
