Monitoring dioxins, PCBs and flame retardants in agricultural and fishery products in 2008

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（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（brominated flame retardants，缩写BFRs）以及多氟和全氟烷基物质（PFASs）的检测分析，检测对象涵盖肉类、奶类、蛋类及鱼类。 样本采集于初级生产或加工阶段，具体场景包括屠宰场、生乳收集服务站点等。针对类二噁英化合物，研究人员首先采用DR CALUX®检测法对350份样本进行初筛；若样本信号显示其含量超过最低行动水平，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（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，研究团队约采集25份样本，采集渠道包括远洋科研船舶采集、鱼拍卖行交易环节，以及批发商渠道的养殖鱼类样本。
