Maine State
In April 2024, the State of Maine, led by Attorney General Aaron Frey, filed a high-profile environmental lawsuit against Monsanto (a subsidiary of Bayer) in Cumberland County Superior Court. The complaint alleges that Monsanto manufactured and marketed products containing polychlorinated biphenyls (PCBs) despite decades of evidence of their toxic effects, persistence in the environment, and significant health risks. Maine asserts that Monsanto continued to sell PCB-based products long after internal and external evidence demonstrated their hazards, prioritizing financial interests over environmental safety and public health.
The state alleges that PCBs have contaminated rivers, sediments, and marine ecosystems, resulting in impaired waters and seafood consumption advisories. This contamination has impacted fisheries, wildlife, and exposed communities to potential health risks. The lawsuit seeks accountability, recovery of remediation costs, and funding for monitoring and cleanup, positioning Maine within a broader wave of state-led toxic tort actions against corporate polluters.
On April 11, 2024, Maine filed a complaint against Monsanto in Cumberland County Superior Court. The lawsuit alleges that Monsanto continued to produce and distribute PCB-containing products despite clear evidence of their dangers to public health and the environment. The complaint identified more than 400 miles of rivers and streams and nearly 1.8 million acres of ocean waters impaired by PCB contamination. Maine seeks recovery of cleanup, monitoring, and mitigation costs for decades of environmental damage to rivers, coastal ecosystems, and local communities.
On December 16, 2024, Monsanto filed a motion to dismiss, arguing that Maine’s claims lacked sufficient legal basis. The Superior Court denied the motion, finding that the state had plausibly alleged claims under public nuisance, negligence, and strict liability theories. This rule allowed the case to proceed into discovery, where Maine will seek further evidence and expert testimony linking Monsanto’s conduct to long-term ecological harm and public health risks. The denial of the motion marked a significant procedural milestone in the litigation.
Environmental contamination lawsuits typically involve extensive discovery, expert witness testimony, and detailed damages analysis, leading to long litigation timelines. Legal observers anticipate that trial may not occur until 2026 or later. The extended timeline reflects the complexity of evidence collection, the likelihood of pre-trial motions, and potential settlement negotiations. Meanwhile, PCB contamination continues to affect Maine’s waters and ecosystems, underscoring the urgency of accountability and remediation.

Maine v. Monsanto is a significant environmental lawsuit that underscores the interplay of corporate accountability, toxic chemical regulation, and state-led enforcement. PCBs, banned in 1979, continue to persist in sediments, contaminate food chains, and threaten health decades later. By advancing claims under nuisance, negligence, and strict liability, Maine seeks recovery of remediation and monitoring costs while addressing the enduring effects of toxic exposure. The denial of Monsanto’s motion to dismiss enables the case to proceed into discovery with expert testimony. This litigation has implications for other states dealing with PCB contamination and could influence emerging cases involving PFAS and other persistent pollutants.
What are PCBs and why are they harmful?
Polychlorinated biphenyls (PCBs) are synthetic industrial chemicals once used in electrical equipment, paints, caulks, and other products. They persist in the environment, bioaccumulate in organisms, and are associated with cancer, reproductive harm, immune suppression, and developmental problems.
Why is Maine suing Monsanto specifically?
Maine alleges that Monsanto manufactured and marketed PCBs despite knowing of their dangers, making the company financially responsible for environmental contamination and related ecological and public health impacts.
Has Monsanto faced similar lawsuits in other states?
Yes. Several states, including Oregon, Washington, and Vermont, have filed PCB contamination lawsuits. Oregon reached a $698 million settlement in 2022, while Vermont and others continue to litigate PCB claims.
What legal claims is Maine pursuing?
Maine’s complaint asserts claims under public nuisance, strict liability for design defect and failure to warn, and negligence. The state seeks recovery of cleanup and monitoring costs, natural resource damages, and other expenses related to PCB contamination.
How might this case impact future environmental litigation?
If successful, the case strengthens states’ ability to hold corporations accountable for legacy contamination. It may serve as precedent for lawsuits involving other persistent toxic substances, such as PFAS, which are currently the subject of nationwide litigation.
