Peanut is one of the major food allergens inducing anaphylaxis. It is increasingly consumed and often used as a hidden ingredient, thus making avoidance especially difficult for allergic patients. In Switzerland legislation stipulates that all ingredients of a processed food exceeding 2% of the total mass of the finished food product should be labelled. However, in the case of a mixture of vegetables it can be labelled as "vegetable mix" if it does not exceed 10% of the total weight. Peanut, which is a member of the legume family, can thus form up to 10% of processed foods without being mentioned on the label, thus making avoidance impossible. We report on two patients who presented severe anaphylaxis from peanut hidden in a pizza from a fast food restaurant. We were able to provide evidence for the presence of major peanut antigens in the pizza sauce by immunochemical analysis. These two cases clearly demonstrate the danger of peanut hidden in foods and point up the necessity of a change in legislation.
花生是引发过敏反应的主要食物过敏原之一。其消费量日益增加，且常被用作隐藏成分，这使得过敏患者尤其难以避免接触。在瑞士，立法规定加工食品中所有超过成品食品总质量2%的成分都应进行标注。然而，对于蔬菜混合物而言，如果其不超过总重量的10%，则可标注为“蔬菜混合物”。花生属于豆科植物，因此在加工食品中含量可达10%而无需在标签上提及，这就使得无法避免接触。我们报告了两名因快餐店里披萨中隐藏的花生而出现严重过敏反应的患者。通过免疫化学分析，我们能够证明披萨酱中存在主要的花生抗原。这两起案例清楚地表明了食物中隐藏花生的危险性，并指出了立法变革的必要性。
