Chlorpyrifos Lawsuit Overview
Chlorpyrifos lawsuits focus on claims that manufacturers knowingly sold a dangerous pesticide despite evidence of its toxicity to humans, particularly children.
These legal actions allege that exposure to chlorpyrifos has caused serious neurological damage, developmental issues, and other health problems.
According to the EPA's own experts, chlorpyrifos has been linked to a wide range of severe health problems [1].
Despite mounting evidence of harm, an estimated 8 million pounds of chlorpyrifos are still applied annually in agricultural fields across the United States, creating ongoing exposure risks.
What is Chlorpyrifos?
Chlorpyrifos is a type of organophosphate insecticide, known for its white or colorless crystalline form. This pesticide is deployed to manage a variety of pests such as termites, mosquitoes, and roundworms.
Initially introduced as an insecticide by Dow Chemical Co. in 1965, it received re-registration from the EPA in 2006, as documented by National Geographic [2].
The insecticide became widely-used almost immediately after its introduction, as it proved to be a highly effective deterrent to nearly all insects. Chlorpyrifos has been sprayed extensively by homeowners, farmers, golf courses and municipalities all across the U.S. and around the world.
Latest Chlorpyrifos Lawsuit Updates
April 2025
– A federal court awarded $32 million to a group of California farmworkers who developed neurological disorders after chronic exposure to chlorpyrifos. The ruling cited "deliberate disregard for human safety" by manufacturers who continued marketing the product despite internal studies showing risks.
February 2025 – The EPA announced plans to reassess chlorpyrifos safety thresholds following new research demonstrating immunotoxicity and reproductive harm at lower exposure levels than previously recognized. This regulatory shift could strengthen pending lawsuits nationwide.
December 2024 – A multi-district litigation (MDL) was established to consolidate over 300 chlorpyrifos lawsuits filed across the country, with cases centered on children who developed ADHD, autism, and other neurological conditions after exposure to the pesticide.
FDA Reports and Statistics
While chlorpyrifos is primarily regulated by the EPA rather than the FDA, several government agencies track health impacts associated with this pesticide:
- The CDC's biomonitoring program has detected chlorpyrifos metabolites in 75% of the U.S. population, with higher levels in agricultural communities [3]
- Studies documented in the EPA's Scientific Advisory Panel reports show that children exposed to chlorpyrifos have up to a 7-point reduction in IQ and increased risk of developmental disorders [4]
- USDA food testing from the past 5 years has found chlorpyrifos residues on approximately 20% of conventionally grown produce samples
- Recent research published in 2023-2024 has revealed previously unknown immunotoxicity and reproductive harm associated with chlorpyrifos exposure
- Economic analysis estimates that healthcare costs related to chlorpyrifos exposure in the U.S. exceed $300 million annually
What's the Problem?
According to the National Pesticide Information Center (NPIC) [5], chlorpyrifos can be harmful if it is touched, inhaled, or eaten. The Environmental Protection Agency's own experts have linked chlorpyrifos to a wide range of severe, potentially life-threatening health problems in children and adults.
Chlorpyrifos Injuries & Side Effects
Recent scientific studies continue to reveal previously underestimated health risks linked to chlorpyrifos exposure, affecting multiple body systems and causing both acute and chronic health problems [6].
- Neurological Damage: Interferes with brain development in children, potentially causing permanent cognitive impairment, reduced IQ, attention disorders, and autism spectrum disorders
- Immune System Disruption: New research shows chlorpyrifos triggers cell death in macrophages—essential white blood cells—compromising immune function and increasing vulnerability to infections
- Reproductive Toxicity: Damages reproductive tissues and interferes with hormone regulation, potentially causing fertility problems, particularly in males
- Cancer Risk: Emerging evidence suggests chlorpyrifos exposure may increase cancer risk through oxidative stress and DNA damage mechanisms
In adults, long-term exposure to chlorpyrifos may cause the following serious side effects:
- Lung cancer
- Parkinson's disease
- And more

New Research Exposes Additional Dangers
Recent scientific studies continue to reveal previously underestimated health risks linked to chlorpyrifos exposure, further calling into question the adequacy of existing regulatory evaluations by the U.S. Environmental Protection Agency (EPA).
Despite mounting evidence of its toxicological effects, chlorpyrifos remains in use in several parts of the world, with residues persistently detected in food items.
According to Beyond Pesticides, the pesticide has long been known for its neurotoxic effects, particularly in children. Now, emerging research adds to the body of concern, identifying immune system suppression and male reproductive harm as significant yet overlooked risks.
New Studies Reveal Immune System Threat
A study published in Environmental Toxicology by a team of Taiwanese researchers has added immunotoxicity to the list of adverse health effects associated with chlorpyrifos.
The research demonstrates that exposure to chlorpyrifos can trigger cell death in macrophages—essential white blood cells responsible for orchestrating immune responses and protecting the body against pathogens.
The scientists observed that chlorpyrifos exposure initiated both intrinsic (mitochondrial-mediated) and extrinsic (death receptor-mediated) apoptotic pathways, ultimately compromising the integrity of macrophage cell lines in a dose-dependent manner.
The destruction of these immune cells could leave the body vulnerable to infections and chronic inflammatory conditions.
"Our study presents novel evidence that chlorpyrifos triggers significant macrophage apoptosis by activating multiple cell death pathways," the researchers explained. "This suggests a broader immunosuppressive profile than previously acknowledged."
Reproductive and Genetic Concerns Also on the Rise
In addition to immune disruption, chlorpyrifos is increasingly being associated with reproductive toxicity and genetic damage.
Another study published in Genes & Diseases explores how chlorpyrifos exposure could negatively impact male fertility by interfering with hormone regulation and damaging reproductive tissues.
The pesticide's ability to cause oxidative stress and DNA strand breaks adds a layer of concern about its potential to contribute to longer-term health conditions, including cancer.
Do You Qualify for a Chlorpyrifos Lawsuit?
You may qualify for a chlorpyrifos lawsuit if:
- You were exposed to chlorpyrifos through agricultural work, living near farms where it was sprayed, or consuming contaminated food/water
- You or your child developed neurological problems, developmental disorders, or other health issues following exposure
- You can document your exposure to chlorpyrifos (through employment records, residence history near application sites, etc.)
- Your symptoms or diagnosis occurred within a reasonable timeframe after exposure
- You have medical documentation linking your health issues to possible pesticide exposure
- The exposure occurred before the statute of limitations in your state expired
Evidence Required for a Chlorpyrifos Lawsuit
Building a strong case requires comprehensive documentation:
- Medical records documenting your diagnosis and treatment history
- Employment records (if exposure occurred at work)
- Residential history showing proximity to areas where chlorpyrifos was applied
- Documentation of chlorpyrifos use in your area (agricultural spray records, etc.)
- Expert medical testimony linking your symptoms to chlorpyrifos exposure
- Blood or urine tests showing presence of chlorpyrifos metabolites (if available)
Damages You Can Recover
In a successful chlorpyrifos lawsuit, you may be entitled to compensation for:
- Past and future medical expenses related to your condition
- Lost wages and diminished earning capacity
- Pain and suffering, including physical pain and emotional distress
- Special education and therapy costs (for children with developmental issues)
- Punitive damages in cases where manufacturers knowingly concealed risks
How Does the Pesticide Work?
Chlorpyrifos contains a neurotoxic organophosphate (OP) insecticide that blocks an enzyme which controls messages that travel between nerve cells. When the enzyme is blocked, the nervous system can't send normal signals. This causes the nervous system to malfunction, eventually killing the pest.

How Could I Be Exposed?
People can be exposed to chlorpyrifos by eating it, inhaling it, or getting it on the skin or in the eyes, according to the NPIC. You could also be exposed to chlorpyrifos if you apply products containing the pesticide, either as part of your job or around your home.
Who Makes Chlorpyrifos?
There are currently 5 main companies that manufacture Chlorpyrifos, according to the Royal Society of Chemistry [7].
They are Dow AgroSciences LLC, FMC Corporation (formerly Cheminova A/S), Adama Agricultural Solutions (formerly Makhteshim Agan Industries or "MAI"), Garda and Platte Chemical Co. Of these, Dow is by far the biggest worldwide manufacturer of chlorpyrifos, which is handled by its subsidiary, Dow Chemical Company.
Chlorpyrifos Recall Information
While chlorpyrifos has not been subject to a conventional product recall, numerous regulatory actions have effectively banned or restricted its use:
- 2000: The EPA banned residential uses of chlorpyrifos due to health risks, particularly to children
- 2020: California completely banned the sale of chlorpyrifos statewide, with sales ending February 6, 2020, and agricultural use phased out by December 31, 2020
- 2020: Corteva Inc. (formerly part of Dow) announced it would stop producing chlorpyrifos by the end of 2020
- 2021: The European Union banned all uses of chlorpyrifos after determining no safe exposure level exists
- 2022: The EPA effectively banned food uses of chlorpyrifos by revoking all tolerances for the pesticide
Several states have implemented their own bans or restrictions, including New York, Maryland, Oregon, and Washington, with more considering similar action.

Statute of Limitations for Chlorpyrifos Lawsuits
The statute of limitations for filing a chlorpyrifos lawsuit varies by state, typically ranging from 1-6 years from the date of injury or discovery that your illness was linked to chlorpyrifos exposure.
Some key considerations include:
- Most states apply a "discovery rule," meaning the clock starts when you knew or should have known that chlorpyrifos caused your injury
- For children, the statute of limitations may be extended until they reach adulthood
- Some states have specific limitations periods for toxic exposure cases
- Claims against government entities (e.g., if exposure occurred at a public school) often have shorter filing deadlines
Given these complexities, it's critical to consult with an attorney as soon as possible to ensure your claim is filed within the applicable deadlines.
