Monitoring dioxins, PCBs and flame retardants in agricultural and fishery products in 2010

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).

受农业、自然与食品质量部（LNV）委托，瓦赫宁根食品安全研究所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)及全氟与多氟烷基类物质(PFASs)的检测分析，检测对象涵盖肉类、奶类、蛋类与鱼类。
样品采集环节涵盖初级生产与加工阶段，例如屠宰场、生奶收集站点。针对二噁英类化合物，研究团队首先采用DR CALUX®检测法对350份样品进行初筛；若初筛结果显示目标物浓度超出最低行动限值，则将该样品判定为疑似阳性样品，后续再采用气相色谱/高分辨质谱(GC/HRMS)作为确证方法进行复检。针对鱼类、贝类及甲壳类动物产品，研究人员会通过科考船在海上、鱼品拍卖场或批发商（养殖鱼类）处采集约25份样品。
