  ABSTRACT: A survey of pesticide residues in 600 imported fruit products on the Tokyo market from April 1994 to March 2006 was carried out. Thirty kinds of pesticides, including organophosphorus, organochlorine, carbamate, and pyrethroid, were detected between levels of Tr (below 0.01 ppm) to 0.37 ppm from 75 samples. Residual pesticides were detected from fruit products, dried fruits and pressed juice. A high frequency of pesticide residues was observed in peels, whole body of fruits and products which contained them. Residue levels of these pesticides were calculated as between less than 0.1 and 3.9% of their ADI values according to the daily intake of fruit products. Therefore, these fruit products should be safe when eaten in customary amounts.

  ABSTRACT: A survey of pesticide residues in 490 imported cereal products on the Tokyo market from April 1994 to March 2006 was carried out. Eight kinds of organophosphorus pesticides (chlorpyrifos, chlorpyrifos-methyl, DDVP, diazinon, etrimfos, malathion, MEP and pirimiphos-methyl) were detected at levels between Tr (below 0.01 ppm) and 0.82 ppm from 91 samples. In our investigations, chlorpyrifos-methyl and malathion tended to be detected in samples from America, pirimiphos-methyl in those from Europe, and MEP in those from Oceania. Thus, pesticide residues seemed to be different in produce from different areas. Residue levels of these pesticides were calculated as between 0.08 and 13.2% of their ADI values according to the daily intake of cereal products. Therefore, these cereal products should be safe for normal usage.
