The results of the feeding studies will be subjected to a peer review process by a high-ranking scientific journal as a quality assurance step. At that step interpretations and conclusions will be limited to the feeding studies. A draft version of the manuscript will also be part of to the stakeholder documents in the stakeholder workshop at the final stage of the project. Another set of journal manuscripts will focus on the general conclusions for GMO risk assessment.


All papers will be put open access and accompanied by a discussion forum in the journal for commenting on these papers. This strategy allows the scientific discussion to continue beyond the lifetime of the Project. Archives of Toxicology, a high-ranking scientific journal, has agreed to go along with this publication strategy. This journal already published a letter describing the three major long term feeding studies with GM plants in the EU: GRACE, GMO90+ and G-TwYST.

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.
