Secondhand Paraquat Exposure: The Hidden Danger in Your Home

Secondhand Paraquat Exposure: The Hidden Danger in Your Home

For decades, Paraquat has been one of the most widely used herbicides in American agriculture. It is incredibly effective at killing weeds, but it is also incredibly toxic. While agricultural workers who spray the chemical directly face the most obvious risks, a growing body of evidence suggests they are not the only ones in danger.

“Secondhand exposure”—also known as “take-home exposure” or “para-occupational exposure”—is a serious threat that has largely gone unnoticed until recently. Families living near farms or sharing a home with agricultural workers may be breathing in or coming into contact with this dangerous chemical without ever setting foot in a field.

If you or a loved one has developed Parkinson’s disease and suspect it might be linked to Paraquat, understanding how this exposure happens is the first step toward protecting your rights. At Walch Law, we are helping families connect the dots between their diagnosis and environmental toxins they never knew they were absorbing.

What Is Secondhand Paraquat Exposure?

Most people assume that if they aren’t the ones spraying the chemical, they are safe. Unfortunately, toxins like Paraquat do not respect property lines or doorways. Secondhand exposure occurs when a person inadvertently comes into contact with a chemical that was applied elsewhere or brought into their environment by someone else.

Paraquat is a restricted-use pesticide, meaning only certified applicators can buy and use it. However, once it is sprayed, microscopic particles can drift through the air, settle on clothing, or seep into the soil and groundwater. This creates a radius of danger that extends far beyond the crop rows.

For families in agricultural communities, this means the air you breathe and the dust in your home could be carrying traces of a chemical linked to severe neurological damage.

Where Are You Most Likely to Get Secondhand Exposure?

Secondhand exposure is not random; it is typically concentrated in specific areas and situations. If you live or work in these environments, your risk significantly increases.

1. Living Near Agricultural Fields (The “Spray Drift” Zone)

The most common source of secondhand exposure is simply geography. If your home, school, or workplace is located near a farm, vineyard, or orchard where Paraquat is used, you are in the “spray drift” zone.

When Paraquat is sprayed from tractor rigs or crop-dusting planes, wind can carry fine mist and particles for miles. This “drift” settles on:

• Your Yard: Coating outdoor furniture, children’s toys, and garden vegetables.
• Your Home: Entering through open windows or vents.
• The Air You Breathe: Creating a persistent, invisible inhalant risk during spraying seasons.

Studies have shown that residents living within a few miles of Paraquat-treated fields have a significantly higher risk of developing Parkinson’s disease than the general population.

2. Inside the Home of an Agricultural Worker (“Take-Home” Exposure)

The second major vector for exposure is “take-home” toxicity. This happens when a farmworker unknowingly brings Paraquat residue home on their body or belongings.

Paraquat particles are sticky and persistent. They cling to:

• Clothing: Work shirts, jeans, and hats.
• Boots: Tracking contaminated soil into the house.
• Skin and Hair: Transferring to furniture, bedding, or other family members through physical contact.
• Vehicles: Steering wheels and seats of trucks driven home from the fields.

Once inside the home, this residue can settle into carpets, furniture, and house dust. Family members—including spouses and children—then absorb the toxin through their skin or inhale it as dust is kicked up. This puts entire households at risk, even if only one person works in agriculture.

3. Rural Schools and Playgrounds

Children are particularly vulnerable to chemical exposure because their bodies are still developing. Rural schools located adjacent to farmland are often in the direct path of pesticide drift. Recess on a playground downwind from a spraying operation can expose dozens of children to toxic mist.

Furthermore, children playing in fields, irrigation ditches, or near farm equipment may come into direct contact with contaminated soil or water runoff.

The Health Risks: Connecting Paraquat to Parkinson’s Disease

The primary health concern associated with chronic Paraquat exposure is Parkinson’s disease. Unlike immediate poisoning, which causes lung damage and organ failure, chronic low-level exposure works slowly.

Paraquat creates “oxidative stress” in cells. It is particularly damaging to the neurons in the brain that produce dopamine—the chemical responsible for controlling movement. When these dopamine-producing neurons die, the classic symptoms of Parkinson’s disease begin to emerge:

• Tremors or shaking in hands and limbs
• Stiffness and slow movement (bradykinesia)
• Impaired balance and coordination
• Difficulty speaking or writing

Research indicates that exposure to Paraquat can increase the risk of developing Parkinson’s by 150% or more. Because the disease can take years or even decades to manifest, many people do not immediately link their diagnosis to the farm they lived near twenty years ago.

Your Legal Rights: Holding Manufacturers Accountable

If you have been diagnosed with Parkinson’s disease and lived or worked in an area with high Paraquat usage, you may have a valid legal claim.

Manufacturers like Syngenta and Chevron have a duty to ensure their products are safe or to provide adequate warnings about the risks. Lawsuits allege that these companies knew for decades that Paraquat was neurotoxic and capable of causing Parkinson’s but failed to warn the public or agricultural workers. They also allegedly failed to design the product in a way that minimized drift and take-home exposure risks.

Proving Secondhand Exposure
In a legal case, proving secondhand exposure requires a detailed investigation. We do not need a receipt showing you bought Paraquat. Instead, we look for evidence such as:

• Residential History: Mapping your home’s proximity to agricultural fields during key timeframes.
• Employment Records: Showing a family member worked as a pesticide applicator or farmhand.
• Medical Records: Documenting your Parkinson’s diagnosis and ruling out genetic causes.
• Expert Testimony: Using agricultural experts to model spray drift patterns and establish the likelihood of exposure in your specific location.
