The overall concept is to allow for stakeholder engagement in the key steps of the Project: the planning stage -at the start of the project- as well as the interpretation and conclusion stage. For each step workshops are held and a procedure for written comments will be established based on draft documents (draft study plan, draft results and interpretations).


Planning stage workshop

One workshop was held in December 2014 for the planning stage. The aim of the planning stage consultation was to explain and to discuss the draft study plan which will be sent to interested stakeholders prior to the workshop.


The draft study plans, presentations held by G-TwYST partners and a report of the workshop is also available in the Documents & Reports section of this website.


Interpretation and conclusion workshops

Two workshops will be held back-to-back for the interpretation and conclusion stage (March 2018), bringing together three topics:

  1. The interpretations of the results and conclusion of the animal studies.
  2. The draft considerations on the scientific value of this type of studies for GMO risk assessment.
  3. The results and draft interpretations and conclusions from the analysis of the broader societal issues.


Read more about the final stakeholder workshops.


The consultation documents will include a peer reviewed journal manuscript on the broader societal issues, and draft publications on the results of the feeding studies.



The discussions and comments will be thoroughly documented in consultation reports published at the project website. The revisions of the drafts based on the comments and discussions will be transparently linked to the comments received by providing written responses to stakeholder comments. The results of the discussion and the stakeholder's comments will be considered in revising the manuscripts.


All procedural details for the stakeholder consultations have been laid down in the ‘Stakeholder engagement and communication strategy’.

Comments on statistical methods for safety assessment published

March 6, 2018


In safety assessments a large number of non-target effects  has to be analysed statistically. A recent paper published in the Journal of Agricultural and Food Chemistry advocates an approach which leads to over-optimistic conclusions. In a recent Correspondence to this journal the concerns about the misapplication of methodology are explained. See: Safety Assessments and Multiplicity Adjustment: Comments on a Recent Paper, available on the Journal of Agricultural and Food Chemistry website at http://pubs.acs.org/doi/abs/10.1021/acs.jafc.7b03686.
