Large population studies estimated that the frequency of food allergies is increasing worldwide. In the last two decades, a 'second wave' of the allergy epidemic has emerged as a growing public health problem. EU regulation strengthened information to consumers about allergens in pre-packed food, since December 2014 it has been extended to non-prepacked foods by the Regulation (EU) No 1169/2011 of the European Commission. The present work aims to present a five-year survey on the presence of nine types of allergen in several foods, including food of animal origin and baby food. The concentration found for each irregular allergen is generally low, but some samples with no gluten indication contained a concentration above 10 mg kg-1 with the highest value of 138.5 mg kg-1 in a dietetic food, during the screening in 2017. These data underline the importance and the necessity of a complete food labelling to protect the majority of allergic individuals.

意大利对2014-2018年间未申报食物中过敏原的一项调查。

大量的人口研究估计，全世界食物过敏的频率正在增加。在过去的二十年中，过敏流行的“第二波”已成为日益严重的公共卫生问题。欧盟法规加强了对消费者的预包装食品过敏原信息，自2014年12月起，欧盟委员会（EU）第1169/2011号法规将其扩展至非预包装食品。本工作旨在提出一项五年调查，调查几种食品中包括动物源性食品和婴儿食品在内的九种过敏原的存在。在2017年的筛查期间，营养食品中发现的每种不规则变应原的浓度通常较低，但一些没有麸质迹象的样品中饮食中的浓度超过10 mg kg-1，最高值为138.5 mg kg-1。
