Particularly, they have been time-tested in a complex system. Our tests are not only limited in time, but also in complexity. Scientists take a sample of subjects in a defined environment. The benefit of that is that they can draw definitive conclusions because of the manageable variables. The problem with it is that you fail to see the big picture, the many interactions with the numerous components of a real life activity, and on the long run. When talking about living things and food, or in that case, living things that are food, the context is incredibly important to define what is safe or not.
