We surveyed the presence of allergenic substances such as egg, milk, wheat, buckwheat, peanut, shrimp and crab in foods produced or distributed in Chiba Prefecture during the fiscal years 2004–2014. Six hundred and ninety-five samples that did not display the target allergenic substances were screened by using ELISA. Three percent of the samples (21/695 samples) were found to be positive. Wheat had the highest positivity rate of 9.7% (10/103 samples). Among the samples tested, advisory labeling was displayed in the case of 109 samples. Among these samples, 77.1%(84/109 samples) contained less than 1.0 μg/g of the specified allergen. Out of the 21 samples that tested positive in the screening-test, 16 did not display the advisory labeling.
