EFSA casts doubt on French GMO study

The European Food Safety Authority (EFSA) has cast doubt on the validity of a French study claiming harmful effects to rats from exposure to the herbicide, glyphosate, and Monsanto’s genetically modified glyphosate-tolerant NK603 maize at levels considered safe to humans ( Agrow No 649, p 11). The Authority has found inadequacies in the design, reporting and analysis of the study and views it of insufficient scientific quality to be considered as valid for risk assessment. Saying that no conclusions could be made about the occurrence of tumours in the tested rats, it has asked the authors led by Professor Séralini to share key additional information to “enable the fullest understanding of the study”.
