The migration of phthalates into foodstuffs from food-contact materials (FCM) is a well-known source of food contamination. In 2005, the European Food Safety Authority finalized its risk assessment for several of the classical phthalate plasticizers. In their risk management procedure the European Commission transformed the tolerable daily intakes established by the Authority into legislative limits for phthalates in both plastic and food simulants, while taking exposure from other sources into consideration. These limits have been into force since 1 July 2008. A detailed interpretation of the regulation of these substances was agreed upon in the European network of FCM reference laboratories. This paper reports results from a Danish control campaign of samples collected by official food inspectors and analysed by a newly validated analytical method run under accreditation. Samples were from FCM producers, FCM importers and importers of packed foodstuffs from third-party countries. Products containing phthalates above the current limits were found in several categories of FCM: conveyor belts (six of six), lids from packed foodstuffs in glasses (eight of 28), tubes for liquid foodstuffs (four of five) and gloves (five of 14). More than 20% of the samples analysed contained dibutylphthalate (DBP) or di-(2-ethylhexyl)phthalate (DEHP) above the compositional limits of 0.05% and 0.1%, respectively. Analysis of residual phthalates in metal lid gaskets instead of analysis of phthalates in the food when controlling foodstuffs packed outside the European Union proved to be an efficient and simple control method. All findings of phthalates were associated with the use of plasticized polyvinylchloride (PVC).
增塑剂从食品接触材料（FCM）迁移到食品中是食品污染的一个已知来源。2005 年，欧洲食品安全局完成了对几种经典邻苯二甲酸酯类增塑剂的风险评估。在其风险管理程序中，欧盟委员会将管理局确定的可耐受每日摄入量转化为塑料和食品模拟物中邻苯二甲酸盐的法定限量，同时考虑了其他来源的暴露。这些限量自 2008 年 7 月 1 日起生效。在欧洲食品接触材料参考实验室网络中，对这些物质的法规进行了详细的解释。本文报告了丹麦官方食品检验员收集的样本的控制活动结果，这些样本由经认证的新验证分析方法进行分析。这些样本来自 FCM 生产商、FCM 进口商以及来自第三国的包装食品进口商。在几个 FCM 类别中发现了含有当前限量以上邻苯二甲酸盐的产品：输送带（6 个中的 6 个）、装在玻璃杯中的包装食品盖子（28 个中的 8 个）、用于液态食品的管子（5 个中的 4 个）和手套（14 个中的 5 个）。分析的样本中超过 20%的样本含有邻苯二甲酸二丁酯（DBP）或邻苯二甲酸二（2-乙基己基）酯（DEHP），含量分别超过 0.05%和 0.1%的组成限量。在控制欧盟以外包装的食品时，分析金属盖垫圈中的残留邻苯二甲酸盐而不是分析食品中的邻苯二甲酸盐，被证明是一种高效、简单的控制方法。所有邻苯二甲酸盐的发现都与使用增塑聚氯乙烯（PVC）有关。
