Monitoring dioxins, PCBs and flame retardants in agricultural and fishery products in 2019

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, LNV）委托，瓦赫宁根食品安全研究所（Wageningen Food Safety Research）针对动物源农产品样本开展二噁英（dioxins）、多氯联苯（PCBs）、溴化阻燃剂（brominated flame retardants, BFRs）及多氟和全氟烷基物质（poly- and perfluorinated alkyl substances, PFASs）的检测分析工作，检测对象涵盖肉类、奶类、蛋类及鱼类。<br>样本采集自初级生产或加工环节，例如屠宰场、生乳收储服务站点。针对二噁英类化合物，研究人员首先采用DR CALUX®检测法对350份样本进行初筛；初筛结果显示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-高分辨质谱联用（GC/HRMS）作为确证方法开展复检。针对鱼类、贝类及甲壳类动物，约25份样本由科研船在远海采集，或在鱼类拍卖场、批发商（养殖鱼类）处获取。
