大豆Herbicide residues in GM soy and methodological discussions

We have responded to the specific criticisms by Korsaeth et al. (2014) by detailing the information on soybean variety (genetics), yield, soil type and fertiliser use for the analyses of soy composition in our original paper. We acknowledge some relevant and good points of criticism from Korsaeth et al., but we also argue for the value of broader comparisons of crop products produced using different agroecological systems, e.g. GM, conventional and organic agriculture. Further, the restrictions of research material from GM crops strongly limit independent research. This is not acceptable.

We also provide a perspective on the criticism by highlighting serious flaws in current test practices for GM plants. In spite of some limitations in our study design, we are still convinced that our paper is important as it raises relevant questions on the safety evaluation of GM crops. This is particularly true with reference to residues of herbicides in herbicide-tolerant GM plants; these residues simply fall outside the remit of regulatory authorities. Thus herbicide residues are insufficiently monitored; they are not part of the regular risk assessment procedure, and they are not included in most feeding studies. But you will find them in Roundup Ready GM soy products on the market.

NIFES has mentioned this study in one of their news stories.
