On 16-17 December 2014 G-TwYST organised a worskhop in Vienna to discuss draft study plans with stakeholders. Some 700 stakeholder contacts representing

Competent Authorities, both at the EU and the national level of all 28 Member States, industry, farming and professional organisations, civil society organisations (CSOs) and scientists in received a safe-the-dat note in September 2014 followed by a more detailed invitation with a preliminary agenda in October. Participation in the workshop was open to anyone representing one of the stakeholder categories mentioned above

41 stakeholders from 14 Member States, USA and Norway participated in the workshop. The graphic indicates the participation of the different stakeholder groups.

 

Stakeholders were encouraged to submit written comments after the workshop. We received a total of more than 100 comments. All comments were carefully considered and replied to by members of the G-TwYST team.

 

This has resulted in a number of documents that are  available for download:

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
