2012 - Monitoring dioxins, PCBs 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.<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）将针对动物源农产品中的二噁英（dioxins）、多氯联苯（PCBs）、溴化阻燃剂（BFRs）以及多氟和全氟烷基物质（PFASs）开展样本检测工作。本次检测覆盖肉类、奶类、蛋类及鱼类。样本采集环节覆盖初级生产或加工阶段，具体包括屠宰场或生乳收集服务站点等场景。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；若样本的检测信号显示其浓度高于最低行动限值，则将其认定为疑似阳性样本，此类样本将采用气相色谱-高分辨质谱联用法（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，研究人员约采集25份样本，采集渠道涵盖科研船海上采样、鱼类拍卖行采样，以及从批发商处获取的养殖鱼类样本。
