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 available in the publications section of this website.

 

Interpretation and conlusion workshops

Two workshops will be held back-to-back for the interpretation and conclusion stage (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.

 

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.

 

Transparency

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’.

1-year feeding study with MON810 on ARTE

In October 2016 ARTE broadcasted "OGM - Mensonges et vérités" (GMOs - Lies and truths) on French and German Television. In this 100 minutes long documentary Frédéric Castaignède sheds light on genetically modified crops, the impact on farmers, biodiversity and human health. We have selected and translated a fragment in which G-TwYST project leader Prof Pablo Steinberg presents the results of the 1-year feeding study with MON810 maize in the GRACE project.

 

The documentary provides a ‘snapshot’ of the GRACE final Conference which took place on November 9-10 2015 in Potsdam, Germany. We refer to videos on the GRACE Youtube channel  for a full account.

 

Paper published describing the statistical approach for equivalence testing in G-TwYST

An open access paper describing the statistical approach for equivalence testing in G-TwYST has now been published in Food and Chemical Toxicology. The method was tested on data from the GRACE project, as described in this paper. We will now progress by applying the method in the statistical analyses of the G-TwYST feeding trials, to be reported first in the statistical reports as project deliverables.

Highlights

  • An equivalence testing method is proposed to assess the safety of regulated products
  • We combine data from a current study with test and control, and historical studies with assumedly safe reference products
  • The method is illustrated with animal feeding studies using genetically modified and reference maize varieties
  • A high statistical power of the equivalence test is the basis for the equivalence criterion
  • Generalized fiducial inference is used to integrate uncertainties from the historical and the current data
