Consultation on the Draft Study Plan of 90-day animal feeding trials with GM maize and alternative in-vitro, analytical and in-silico studies

A draft Study Plan of 90-day animal studies was developed by GRACE team members, discussed in a workshop  held on 3 - 4 December 2012 in Vienna and commented by a written consultation. The detailed consultation report, the revised study plans, and a response from GRACE team members to the questions and comments received in the course of the consultation are already available.

Consultation on the Draft Study Plans of a 1-year animal feeding study and a 90-day longitudinal study

The Draft Study Plans were put on the GRACE website and stakeholders were invited to review and comment on these drafts in writing (electronic consultation via e-mail conducted from Dec 2013-Jan 2014, see also related news article).

Consultation on the results of the 90-day animal feeding trials

The interpretations of the results of the 90-day animal studies with GM maize were discussed at a workshop on 19-20 May 2014 in Brussels. On top of the workshop there was a written consultation step.

A consultation report summarises the presentations, comments and discussions at the  workshop as well as the written comments received. It also includes the responses of the GRACE team to the written comments.

The results of the 90-day animal studies with GM maize were summarised in a draft paper and subjected to Archives of Toxicology for peer review in order to ensure external quality assurance.In October 2014 the paper was published.

Consultation on the interpretation of the results of the 1-year animal feeding study and of the alternative studies and of the overall conclusions which can be derived from the animal feeding trials and alternative studies.

This consultation will take place on 7-8 October 2015 (Vienna, Austria). More information are available here.

GRACE Database

Improving the availability of scientific information on GM plants


The database CADIMA (Central Access Database for Impact Assessment of Crop Genetic Improvement Technologies) contains quality assessed studies and conclusions on the health effects, socio-economic consequences and environmental impacts of GM plants as well as raw data of animal feeding studies and alternative in vitro approaches.

It is currently under development and covers the EU projects GRACE, G-TwYST and PreSto GMO ERA-Net.
