Workshop on read-across: role and guidance in chemical risk assessment

Abstract

The workshop on read-across, held on 27–28 March 2025 in Brussels, Belgium, brought together experts from various organisations to explore the application of read-across in chemical risk assessments. The event aimed to strengthen the use of read-across in chemical risk assessments across organisations, with a focus on regulatory approaches, the technical aspects and EFSA's draft guidance. It provided a platform to share experiences and insights on the role of read-across in chemical risk assessment, its importance in screening, classification and hazard assessment, and the challenges and opportunities associated with its implementation. The insights gained from this meeting will be taken into consideration during finalisation of draft guidance before possible adoption by EFSA's Scientific Committee, as well as to inform the needs and content of post-publication activities.
