U.S. Policy Allows Cancer-Causing Pesticide Use Even Though It Is Not Needed to Grow Food and Manage Land

(Beyond Pesticides, June 24, 2025) As changes in the executive branch of the federal government upend expectations among environmental stakeholders, the regulation of food safety in the United States is being revealed as a rickety structure built over a century with unpredictable and sometimes contradictory additions, extensions, remodels, and tear-downs. In the short term, clarity is unavailable, but there have been calls for revision and strengthening of regulatory processes—requiring lawmaker and regulator willingness to incorporate the vast body of evidence that pesticides do far more harm than good, and that organic regenerative agriculture is the surest path to human and ecological health. News reports out of Costa Rica in May brought public attention to drafted legislation to ban pesticides in the country that the World Health Organization (WHO) has defined as “extremely or highly hazardous, or those with evidence of causing cancer, genetic mutations, or affecting reproduction, according to the Globally Harmonized System (GHS).” The headline sparked a relook in this Daily News at the current and historical failure of U.S. policy, which allows cancer-causing pesticides in food production and land management, despite the booming success of a cost-effective and productive, certified organic sector for which petrochemical pesticides are not needed.

Over the last century, pesticide regulation has been based on two different assumptions about how people might be protected from chemicals that cause cancer and other diseases. Food safety regulation began with the Federal Food, Drug, and Cosmetic Act of 1938 (FFDCA). FFDCA was modified by the Food Additives Amendment of 1958 (which included the notorious Delaney Clause to prohibit cancer-causing pesticides in processed foods). EPA regulates pesticides under the 1947 Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), to which Congress mandated a major revision with the Food Quality Protection Act (FQPA) in 1996—which repealed the Delaney Clause with the codification of risk assessment protocol that allows for uncertainty, ignores preexisting health conditions and vulnerabilities, fails to evaluate chemical mixtures and synergistic effects, and establishes levels of acceptable harm.
