Abstract: The objective of this research is to determine the factors that influence the outcomes of previous scientific research on the potential adverse effects of glyphosate-based herbicides (GBH) on human and animal health and the environment. The emphasis is placed on answering the questions about the causal linkages between who funds and performs the research and the research outcomes. A lack of change in use of the GBHs in agriculture stems directly from public (Government) support of the position how the GBHs are safe for humans and the environment. The results of our meta-analysis clearly demonstrate how large and growing majority of influential research on the subject suggests otherwise. Early research on the subject, prior to 2010, done by private and public sector researchers was strongly indicating how GBHs are safe for humans, animals and the environment. It is possible that there is inertia in food safety policy leading to this large gap and disconnect between the results of hundreds of more recent studies and the (current) course of public policy. This study helps us better understand why science on this subject has not been conclusive and thus not the main driver of “science-based” policies about the GBH based production of genetically modified foods. The importance and the implications of this research are obvious: Evidence-based decisions and policies informed by rigorous research and unimpeded by other interested parties are necessary when it comes to developing public policy that affects food safety and in turn human and animal health, and the environment.
