Document (1.22 MB)

EFSA’s Scientific Committee has developed a draft guidance document providing generic issues and criteria to consider biological relevance, particularly when deciding on whether an observed effect is of biological relevance, i.e. is adverse (or shows a positive health effect) or not. The opinion clarifies a number of definitions and concepts, such as, responses of a biological system to exposure, mode of action and adverse outcome pathways, thresholds, critical effect, modelling approaches, biomarkers, which are central to biological relevance and in order to achieve that these concepts are used in a consistent way across EFSA areas of activity. Several case studies covering the various EFSA areas are referred to in the guidance and annexed to the opinion to illustrate the proposed approach. Following this public consultation, the scientific committee will review the contributions and consider them in developing the final version of the guidance document.

In line with EFSA’s policy on openness and transparency and in order for EFSA to receive comments from the scientific community and stakeholders, EFSA has launched public consultations on this draft document. Interested parties are invited to submit written comments by 1 May 2017.
