EFSA has launched an open consultation on the draft report of the EFSA-WHO Expert Workshop on the Threshold of Toxicological Concern Approach: Conclusions and Recommendations.

EFSA and WHO initiated a project aimed at generating recommendations on how the TTC framework could be improved and expanded by updating/revising the Cramer classification scheme and extending the TTC approach, thereby building on existing and ongoing work in this area. A call for data was issued by the WHO in 2013 and information was collected regarding new proposals and scientific work in the area. 

The overall goal of the project is to develop a globally harmonised decision tree for a tiered approach to the application of TTC in the risk assessment of chemicals.

To gain the broadest possible input for this project, a stakeholder public hearing was organised on 2 December 2014 in Brussels, attended by around 100 people reprsenting NGOs, industry, government, academia and consumer organisations (a list of participants is included in annex 1). Stakeholders who had submitted a written request were given the opportunity to express their views with short presentations that have been published on the EFSA website (link here). The points raised by the stakeholders were considered in the subsequent expert meeting held on 3-5 December, for which an open call for experts was published on the WHO website in July 2014.

The expert group agreed a series of conclusions and recommendations, which are available for public consultation on the EFSA and WHO websites until 12 April. Comments received will be considered and addressed by the expert group, and an event report will be published in late spring 2015.
