Several EC Directives have been promulgated to protect allergic individuals but no rule has been established with regard to allergen cross-contamination caused by shared transport vehicles or common processing equipment. The aim of this research was to quantify, by enzyme-linked immunosorbent assay (ELISA) or real-time polymerase chain reaction, the presence in meat- or fish-based foods of four allergens (milk, egg, crustaceans and molluscs) that was not indicated either in the list of ingredients or in the label alert. In the time frame of 2007-2009, a total of 723 samples were subjected to 1983 analyses. The percentage of samples scoring positive ranged between 1.8% and 6.8% over the 3 years, and the concentrations of undeclared allergens found were 0.3-13.3 mg kg⁻¹ for milk (β-lactoglobulin) and 0.21-12 mg kg⁻¹ for egg white proteins. On this basis, the possibility of cross-contamination serious enough to raise public health concern cannot be dismissed.
已颁布了几项欧盟指令来保护过敏个体，但对于由共用运输工具或常见加工设备引起的过敏原交叉污染，尚未制定相关规定。本研究旨在通过酶联免疫吸附测定（ELISA）或实时聚合酶链反应（PCR）来定量检测肉或鱼基食品中四种过敏原（牛奶、鸡蛋、甲壳类动物和软体动物）的存在情况，这些过敏原既未在成分清单中也未在标签警示中注明。在 2007 年至 2009 年期间，共有 723 个样本进行了 1983 次分析。在这 3 年中，阳性样本的比例在 1.8%至 6.8%之间，未申报过敏原的浓度范围为牛奶（β-乳球蛋白）为 0.3-13.3mg/kg 和蛋清蛋白为 0.21-12mg/kg。基于此，不能排除交叉污染严重到足以引起公共健康关注的可能性。
