The registered use conditions of pesticides defined by national authorities are called Good Agriculture Practice leading to different MRLs which may obstruct international trade. The MRLs intended for international use are elaborated by the Codex Committee on Pesticide Residues based on the scientific advice of FAO/WHO Joint Meeting on Pesticide Residues (JMPR). If sufficient data are available, the JMPR recommends MRLs for single commodities and/or commodity groups making best use of residue data and information deriving from relevant supervised trials conducted according to similar critical GAPs, leading to highest residue levels in treated commodities. The stepwise procedure considers trials in one country, within one or several regions taking also into account the proportionality of residue levels and dose rates where applicable. We will stress the challenges of global harmonisation in data generation and sharing, explain the current working principles and stepwise procedures of JMPR, and outline areas of further work.
