Monitoring dioxins, PCBs and flame retardants in agricultural and fishery products in 2017

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）受荷兰农业、自然和食品质量部（Ministry of Agriculture, Nature and Food Quality, 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（brominated flame retardants, BFRs）以及多氟和全氟烷基物质（poly- and perfluorinated alkyl substances, PFASs）开展分析检测。本次检测覆盖的样本类型包括肉类、奶类、蛋类及鱼类。
样本采集环节涵盖农业初级生产或加工阶段，例如屠宰场或生乳收储服务站点。针对类二噁英化合物，研究团队首先采用DR CALUX®检测法对350份样本进行初筛；检测信号显示其浓度高于最低行动限值的样本将被判定为疑似阳性样本，后续将采用气相色谱-高分辨质谱法（GC/HRMS）作为确证方法，对该类疑似样本开展进一步检测。针对鱼类、贝类及甲壳类动物，研究团队将通过研究船在近海海域、鱼类拍卖场，或从批发商处（供应养殖鱼类）采集样本，总计约25份。
