TL;DR: This updated guidance does not call for a general re‐evaluation of previous assessments where the NOAEL approach or the BMD approach as described in the 2009 SC guidance was used, in particular when the exposure is clearly smaller than the health‐based guidance value.

TL;DR: In this paper, a guidance document on the use of the weight of evidence approach in scientific assessments for use in all areas under EFSA's remit is presented, which identifies reliability, relevance and consistency as three basic considerations for weighing evidence.

TL;DR: The European Food Safety Authority has produced this Guidance on human and animal health aspects of the risk assessment of nanoscience and nanotechnology applications in the food and feed chain, which covers the application areas within EFSA's remit.

TL;DR: This document provides concise guidance on how to identify which options for uncertainty analysis are appropriate in each assessment, and how to apply them.

TL;DR: The principles and methods supporting a concise Guidance Document on Uncertainty in EFSA's Scientific Assessment, published separately are described, which provide a flexible framework within which different methods may be selected, according to the needs of each assessment.
