G-TwYST allows for a broad range of stakeholders (industry, professional organisations, civil society organisation, competent authorities, and members of the academia etc.) to engage in all key steps of the project in an inclusive and responsive manner and provides for utmost transparency of what is done and by whom it is done. Moreover, the comprehensive stakeholder consolations reports allow all stakeholders to track how their comments are processed by the scientists in G-TwYST. Thereby, the research process will be fine-tuned and the results and conclusions will not only undergo a traditional scientific peer review but also an extended stakeholder review process.


The stakeholder engagement and communication activities of G-TwYST include:

  1. A stakeholder engagement and communication strategy.
  2. Stakeholder consultations.
  3. Publication of results in an open access journal linked with a discussion forum.
  4. Several dissemination activities and feed-back on the process.


Maximum transparency is a core value in G-TwYST. This principle is applied to study plans, raw data, interpretation of those data, key results as well as to the senior scientists, who have been asked to declare their interests and activities in the field of GMOs and food safety research on a voluntary basis.

G-TwYST Conclusions & Recommendations

29 April 2018


At a Conference held in Bratislava, Slovakia, on 16 April 2018, G-TwYST presented draft conclusions and recommendations regarding guidance on the design, conduct, interpretation, and analysis of animal feeding studies and their value for GMO risk assessment. A final version of G-TwYST Conclusions and Recommendations can be downloaded here.

Final programme 28/29 March available

18 March 2018

The final programma for the G-TwYST stakeholder consultation workshop on March 28 and 29 in Antwerp is available now and can be downloaded here.


This workshop, which is open for interested stakeholders, will focus on the draft results of a 90-day feeding study with 50% inclusion rate of GM maize NK603, as well as a combined chronic toxicity and carcinogenicity feeding study and the overall draft conclusions. Also included in the scope would be proposed quality criteria for whole-food animal feeding studies, and preliminary conclusions on the scientific value of such studies for GMO risk assessment. An additional agenda item will be insights from an analysis of scientific controversies around animal feeding studies including the GMO case.



Written comments, including from interested parties not able to attend, are welcome, and should be submitted before 6 April. Please, note, due to the tight schedule of the final phase of the project, this will be a firm deadline.
