Abstract The risk assessment (RA) requirements for genetically modified plants (GMPs) are defined in Regulation (EU) No 503/2013 and the EFSA guidance on the RA of food and feed from GM plants (EFSA GMO Panel, 2011). When a GMP is developed to silence transcripts by RNA interference (RNAi), some specific additional analysis needs to be provided by the applicant. This guidance describes the requirements and recommendations for the GMP applications submitted to EFSA. It covers the molecular characterisation, focusing on bioinformatic analysis and confirmation of the trait, as well as the food and feed safety and dietary exposure assessment of RNAi‐based GMPs. This document replaces the GMO panel strategy for the risk assessment of RNAi off targets in plants, described in Annex II to the minutes of the 118th Plenary meeting of the Scientific Panel on GMO and takes into account the current knowledge on the mechanisms of RNAi in plants.
