Review of the Statistical Procedures Currently in Use for the Calculation of Maximum Residue Limits
review of a new statistical procedure recently adopted by the OECD (Organisation for Economic Co-operation and Development) for the calculation of the maximum residue levels (MRLs) is provided, based on pesticide residue measurements obtained from supervised field trials. Both theoretical and practical considerations are discussed, and some further opportunities for regulation harmonisation are highlighted. Recently a new statistical procedure for setting maximum residue limits (MRLs) has been adopted by the OECD. This procedure is based on the lessons learned from previous statistical methodologies for MRL calculation used around the world. A comparison of these methodologies and a review of the statistical properties of pesticide residue data are available from a companion paper. After describing the methodology itself, I will discuss its development to illustrate some of the alternatives that were considered and the reasons why they were not selected. I will then point out opportunities to harmonise other statistical pesticide regulations around the world. In what follows, my main references will be the OECD MRL calculator user guide and its statistical white paper.
