Abstract: All genetically modified (GM) plants must undergo a meticulous assessment of their safety before marketing. This involves comparative compositional and other phenotypic analyses between the GM line and a conventional comparator. In the European Union (EU), these comparisons have often been followed by 90-day subchronic toxicity feeding studies. We reviewed 44 peer reviewed articles describing such tests for nine crops since 1995 and 60 opinions of the European Food Safety Authority (EFSA) which have or not included such tests. None of these studies concluded to safety problems. Despite this fact, we noted a drift to systematically include these subchronic rodent feeding studies in the EFSA dossiers since 2009. The recent EU decision to render them mandatory despite the lack of clear scientific necessity to conduct such tests is also discussed.
