The Pesticide Harm Accountability Act would amend federal pesticide law to allow individuals to pursue lawsuits against pesticide manufacturers under state law, even when the EPA has approved the pesticide's label. The bill responds to a 2026 Supreme Court decision that prevented a Missouri man from suing Monsanto over Roundup exposure, which the bill's sponsors argue inappropriately prevented state courts from holding companies accountable. Specifically, the legislation clarifies that federal pesticide law does not prohibit states from requiring additional warning labels that manufacturers would be required to add based on state court judgments. The bill also requires the EPA to report within 180 days on any regulations or guidance documents that restrict state tort claims related to pesticide labeling, and to take steps to align those rules with the legislation. The bill contains no new direct funding but aims to restore a legal pathway for pesticide injury victims to seek damages in state courts.
