We conducted nine consumer surveys using consumer choice experiments between 2011 and 2022. The results show that the value loss of safe foods with very small radiation risks, which are considered scientifically safe, continues more than a decade after the Fukushima Daiichi Nuclear Power Station accident. Although foods distributed in the Japanese market have radiation levels that meet the government safety standard, these very low radiation risks still significantly influence consumers’ food choices and lead to value loss in food products. The results also show that although consumers’ distrust of scientists has a limited impact on the value lost, their distrust in the government is a significant factor in the value loss.
