2017 - 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, LNV）委托，瓦赫宁根食品安全研究所（Wageningen Food Safety Research）将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）以及聚氟和全氟烷基物质（poly- and perfluorinated alkyl substances, PFASs）的检测工作，检测范围涵盖肉类、奶类、蛋类及鱼类。<br>样本采集于初级生产或加工环节，例如屠宰场或生乳收集站点。针对类二噁英化合物（dioxin-like compounds），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超过最低行动水平，则将其判定为可疑样本。此类可疑样本将进一步以气相色谱/高分辨质谱法（GC/HRMS）作为确证方法开展复检。针对鱼类、贝类及甲壳类动物，研究人员会通过研究船在海上、鱼类拍卖场或养殖鱼类批发商处采集约25份样本。
