Monitoring dioxins, PCBs and flame retardants in agricultural and fishery products in 2013

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.<br>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).

瓦赫宁根食品安全研究所（Wageningen Food Safety Research）受农业、自然与食品质量部（Ministry of Agriculture, Nature and Food Quality，缩写LNV）委托，对动物源农产品样本中的二噁英（dioxins）、多氯联苯（PCBs）、溴化阻燃剂（BFRs）及聚氟和全氟烷基物质（PFASs）开展检测工作，检测范围涵盖肉类、奶类、蛋类及鱼类。
样本采集于初级生产或加工环节，例如屠宰场或原奶收集站点。针对类二噁英化合物，首先采用DR CALUX®法对350份样本进行初筛；检测信号显示浓度高于最低行动阈值的样本将被判定为疑似阳性样本，此类样本将通过气相色谱-高分辨质谱法（GC/HRMS）作为确证方法开展进一步检测。针对鱼类、贝类及甲壳类动物，研究船会在海上、鱼类拍卖场或批发商（养殖鱼类）处采集约25份样本。
