Occurence and trend analysis of organochlorine in animal feed

In this report historical data are used to give insight into the trends in levels of organochlorine compounds in compound feeds and feeding materials for animals in the Netherlands. The main focus is on pesticides, but non-dioxin-like PCBs have been studied as well. The latter will be included in the trend analysis reports about dioxins and dioxin-like PCBs in the future. This analysis was performed on request of the NVWA (Netherlands Food and Consumer Product Safety Authority). The results of these analyses will enable the NVWA to develop a risk-directed sampling strategy for the National Feed Monitoring program. More than 5000 feed samples were analysed for organochlorine compounds in the period 2001-2011. The materials in these samples originate from all over the world, but were sampled in the Netherlands. Samples were taken by the NVWA for the Netherlands National Feed Monitoring program and by the feed industry
