The herbicide glyphosate has been tested and approved by both the FDA and the USDA, as evidenced by many published research papers, i.e., they are deemed safe for humans, animals, and the environment. However, evidence is mounting that glyphosate interferes with many metabolic processes in plants and animals, and glyphosate residues have been detected in both. The factors that influence the outcomes of previous scientific research on the potential adverse effects of GBH on human and animal health and the environment were investigated. Using DAGs and Granger causality tests, the study found that while private and public organizations were more likely to generate research indicating that GBH was not harmful, public funding and universities were more likely to produce research indicating that GBH was hazardous. Policy actions should be guided by independent research comprised of actors from major stakeholders and research organizations.
