Public perceptions are significantly more concerned about agricultural chemicals including pesticides, feed additives, and animal drugs than food safety experts. To address these perceptions, we estimated the mean daily intake of 28 agricultural chemicals across the entire Japanese population (≥ 1 year old) using the total diet samples based on the market basket method (14 food groups). The survey was conducted with the collaboration of six local government research institutes (Hokkaido, Tohoku, Kanto, Kansai, Chugoku, and Kyushu) from 2019 to 2021. The estimation of the mean daily intake of residual agricultural chemicals through the consumption of each food group was calculated by multiplying the concentration in the respective food group by the daily food consumption. The highest ratio of estimated daily intake over acceptable daily intake was observed for acephate (0.39%). The contribution rates from crops were higher than those from livestock and aquatic products for many agricultural chemicals. Our results show that all of agricultural chemicals evaluated in this study were far below the ADIs, and these findings considered to be useful to bridge the perception gap.
