We evaluated the performance of a GC-MS/MS method for quantifying 16 polycyclic aromatic hydrocarbons (PAHs), which the Scientific Committee on Food and the Joint FAO/WHO Expert Committee on Food Additives have considered to be of concern to human health, and used the method to determine their concentrations in smoked foods. Eighty-seven samples of smoked fish, smoked meat, smoked eggs, dried bonito flakes, and dried bonito-related soup-stock products (disposable powder packets for infusion, instant bouillons, and liquids) were purchased in Japan to analyze their content of the 16 PAHs. Because of the low certainty of some results, the analytical values for some PAHs (e.g. benzo[c]fluorene, chrysene, and dibenzo[a,h]pyrene) are given for informational purposes only. The highest median concentrations of benzo[a]pyrene and the sum of all the 16 PAHs (29 and 760 μg/kg, respectively) were found in the disposable powder packets followed by dried bonito flakes (24 and 51 2 μg/kg, respectively), and instant bouillons (11 and 2 27 μg/kg, respectively). These concentrations were much higher than those in the other products tested. We also investigated the percentages of the PAHs transferred from dried bonito flakes and a disposable powder packet to soup stocks commonly prepared at home. These were extremely low (< 4%), even though they contained relatively high concentrations of the PAHs. Finally, the intake of BAP and the sum of the intakes of 4 PAHs, as a marker proposed by the European Food Safety Authority, were estimated based on the data from Japanese food consumption survey and the mean concentrations found in smoked fish and smoked fish products. These estimates suggest intakes of PAHs pose a low concern for consumer health.
