EFSA and the German Federal Institute for Risk Assessment (BfR) are jointly holding an International Conference on Uncertainty in Risk Analysis, subheaded “Challenges and Advances in Assessing, Managing and Communicating Uncertainty”, in Berlin on 20-22 February 2019.

The event brings together internationally recognised leaders in theoretical and applied uncertainty analysis with a focus on the areas of food safety, environmental health, occupational health, animal health and plant health.

The conference will be a forum for discussing the science behind uncertainty analysis and showcase best practices in conducting and communicating uncertainty analysis as well as for addressing uncertainty in decision making.

Networking and sharing experience at the conference is anticipated to enhance the mutual understanding and interaction of partners in risk analysis and support and enhance the practice of uncertainty analysis.

The conference is a two-day event with preconference workshops and will be composed of invited and submitted talks, poster sessions and interactive sessions.

Registration and submission of workshop proposals and abstracts:

To register and for information on how to submit workshop and abstract proposals, please see the conference page on the BfR website:

Registration for the conference is closed due to capacity limitation.

Abstracts for posters can be submitted online until 28 January, 2019.

This is the preliminary conference programme subject to changes. Please note that the draft plan allocates equal time slots (20 min each) to both invited and submitted papers presented in the same session. The final programme will be decided by the scientific committee.
