In response to a request from the European Commission, EFSA has developed a guidance document that provides the information necessary to perform the risk assessment of plant protection active substances that contain stereoisomers in its composition as active components or impurities.
The guidance should also be used for active substances that without containing any stereogenic element may generate transformation products or metabolites that do contain them. Current data requirements in the EU regulatory framework (Regulation (EC) No 1107/2009) already establish that the substance tested should match the technical specifications (including its isomeric composition) and that formation and effects of metabolites, degradation and transformation products should be investigated (which certainly includes the case when transformation products are stereoisomers). The guidance is to be used by pesticides applicants and Member States in the preparation of dossiers containing isomers and in the evaluation of such substances by the Member States and EFSA. The issue of the evaluation of substances containing stereoisomers has also attracted the attention of consumers organizations and general public. Therefore, it is appropriate to carry out a public consultation to collect the views of stakeholders and citizens and give them the opportunity to request clarifications.
