Minimum performance requirements for analytical methods of GMO testing: supplement on digital PCR and recommendations for detection of new genomics techniques and GM animals

Abstract The Working Group on Method Performance Requirements (WG-MPR) of the European Network of GMO Laboratories (ENGL) and the EU Reference Laboratory for Genetically Modified Food and Feed (EURL GMFF) have extended the scope of its guidance document on the “Definition of minimum performance requirements for analytical methods of GMO testing”. This document establishes criteria for the development and validation of methods for GMO analysis, both for EU market authorization applications and for official food and feed control. The guidance outlines definitions and performance requirements for methods used to detect and quantify GMOs and has recently been expanded to include digital PCR methods, the detection of genetically modified animals, and the analysis of products developed using new mutagenesis techniques. The guidance document is freely available on the EURL GMFF website ( https://publications.jrc.ec.europa.eu/repository/handle/JRC125975 accessed 25.02.2025).
