Henk van der Schee (Netherlands Food and Consumer Product Safety Authority)
In the Netherlands both the organic production certification body SKAL biocontrol and the Netherlands Food and Consumer Product Safety Authority analyse samples of organic products to verify organic production. In the presentation the different responsibilities are discussed, the cooperation is described and results of the control programs are given.

The cultivation of organic vegetables is an important challenge in consideration of the actual market’s trends. Also for the raw material used in the supply-chain in order to produce the Fresh Cut Salads.
In this context, there is the risk of ubiquitous occurrence of traces of chemical molecules also present in pesticides: we’ll focus on, for example, Phosphonic acid, Chlorate and Perchlorate.

Bulk sample processing (comminution) is just as important to achieve accurate results as any other step in the overall analytical method, but it is usually neglected in method validation, measurement uncertainty calculations, routine quality control, and proficiency testing. Shouldn’t the comminution step be treated like all other parts of the method?

There are many challenges to understanding how honey bees are impacted by pesticides. The analytical challenges are in the need to measure multiple different pesticides at trace levels in small amounts of complex matrixes from multiple routes of exposure. Solving these challenges has shown that honey bees are exposed to multiple pesticides at different concentrations over different time periods. This talk will focus on these challenges and their solution. It will also touch on the challenges in conducting toxicological studies with honey bees to understand what the exposure does to the bees.

It is a great challenge for risk communication regarding pesticide residues to transport key issues on the regulation and safety of pesticide residues to consumers with the aim to overcome concerns and distrust. Pesticide residues are closely regulated and monitored to ensure a high level of protection of human health, but risk perception of consumers regarding this topic shows great fears.

A Swiss federal decision on pesticide residues in organic food will be presented. It defines intervention levels, gives instructions to control and enforcement bodies including measures to be taken and outlines prerequisites such as traceability back to the farm. Some special cases will be shown and still open questions addressed.
