title: Survey of Allergenic Substances in Foods in Chiba Prefecture (Fiscal Years 2004-2014).
abstract: 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.
