FiBL Residues Working Group

The FiBL Residues Working Group provides scientific expertise and advisory services for all questions relating to residues in organic food and feed and develops solutions to ensure the integrity of the organic sector.

Organic farming prohibits the use of synthetic pesticides. However, due to the widespread and intensive use of these substances in conventional production, traces of synthetic pesticides as well as other contaminants sometimes end up in organic products.

The new EU organic legislation requires operators at every stage of production, preparation and distribution to take precautionary measures to avoid the presence of unauthorised substances. Identifying potential risks and defining adequate precautionary measures requires expert knowledge from farmers, processors, traders, retailers, certifiers and authorities. Experience shows that not all actors have the same level of know-how and need more guidance on the practical implementation of the EU organic regulation. At the moment the handling and follow-up on residue cases in organic food and feed are not always harmonised across the EU.

Sampling and analysis have become important tools for quality assurance, as well as to protect organic production against fraud. However, many residue cases are not related to fraud, and the identification of the most likely causes is challenging and requires expert knowledge. Residue values are only meaningful if the samples have been taken appropriately and analysed with appropriate methods.

FiBL has developed long-standing expertise in the field of residues and contaminants and can provide science-based solutions and support to different stakeholders. In order to address the unsatisfactory situation for the entire supply chain of organic food and feed, FiBL has initiated the Residues Working Group.
