The United States Environmental Protection Agency (USEPA) regulates pesticide use throughout the country. They are the ones who get to decide which chemicals are allowed to be used to produce crops, but they use a lot of industry-funded studies to assess risk. In other words, the producers of the pesticides are the ones funding studies to research if their product is safe or not. This creates a potential conflict of interest because the pesticide manufacturers could be leaving out certain data that would prevent their product from passing the risk assessment.
