Contamination Levels of PCDDs, PCDFs and Co-PCBs in Commercial Baby Foods in Japan
Journal of The Food Hygienic Society of Japan (shokuhin Eiseigaku Zasshi)(2005)
Abstract
To examine dioxin contamination in commercial baby foods in Japan, congener analyses of polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and coplanar polychlorinated biphenyls (Co-PCBs) were performed on 102 varieties of baby foods obtained from supermarkets in 2001-2002. The toxic equivalent quantity (TEQ) levels for dioxins in samples ranged from < 0.001 to 0.135 pg-TEQ/g wet weight when undetected or trace levels of congeners were taken as zero. Among 102 samples tested, 26 samples exceeded 0.010 pg-TEQ/g. The highest TEQ value was for sardine, vegetables (0.135 pg-TEQ/g), followed by Japanese radish (daikon), sardine (0.080 pg-TEQ/g). Thus, dioxins were detected at low levels in baby foods containing animal products such as fishes and/or dairy products.
