The recent death of a young girl linked to the consumption of an energy drink, is the demonstration that a more cautious approach to these matters is necessary.
Perhaps even the precautionary approach of the EU is not the best possible rule, but it certainly proves to be more appropriate to meet the challenges of the future in the field of food safety, such as GMOs and nanomaterials.
