Monitoring dioxins, PCBs, PFAS and flame retardants in agricultural and fishery products

On behalf of the Ministry of Agriculture, Nature and Food Quality (LNV), Wageningen Food Safety Research analyses samples of agricultural products of animal origin for dioxins, PCBs, brominated flame retardants (BFRs) and poly- and perfluorinated alkyl substances (PFASs). This includes meat, milk, eggs and fish.The samples are taken at the primary production or processing stage (e.g. in slaughterhouses or raw milk collection services). For dioxin-like compounds, 350 samples are first screened with the DR CALUX® method. Samples giving a signal indicating a level above the lowest action level are regarded as suspected. These samples are further examined using GC/HRMS as confirmatory method. Concerning fish, shellfish and crustaceans, approx. 25 samples are collected at sea by research vessels, at the fish auction, or from whole-sale traders (farmed fish).

受农业、自然与食品质量部（Ministry of Agriculture, Nature and Food Quality，缩写LNV）委托，瓦赫宁根食品安全研究所（Wageningen Food Safety Research）针对动物源农产品开展二噁英（dioxins）、多氯联苯（PCBs）、溴化阻燃剂（BFRs）以及聚全氟烷基物质（PFASs）的检测分析。本次检测覆盖的样品类型包括肉类、奶类、蛋类及鱼类。样本采集环节涵盖初级生产与加工阶段，例如屠宰场、生鲜乳收储站点。针对类二噁英化合物（dioxin-like compounds），研究团队首先采用DR CALUX®检测法对350份样本进行初筛；若样本检测信号显示其污染物浓度高于最低行动阈值，则将其判定为疑似阳性样本。后续将采用气相色谱-高分辨质谱联用法（GC/HRMS）作为确证方法，对上述疑似样本开展进一步检测。针对鱼类、贝类及甲壳类动物，研究团队将通过科考船在远洋海域、鱼类拍卖市场或批发商（养殖鱼类）处采集约25份样本。
