Paraquat is a deadly herbicide that has been
linked to Parkinson’s disease in farmworkers and agricultural communities. It’s
already been banned in more than 50 countries. But in the U.S., paraquat is
still widely sprayed on farms despite staggering evidence that it harms
people’s neurological functioning.
On behalf of farmworker, public
health and environmental organizations, Earthjustice sued the U.S.
Environmental Protection Agency (EPA) in 2021 for allowing paraquat to remain
on the market despite strong scientific evidence of the harm it causes. In response,
the EPA agreed to take another look at that decision.
The data is quite clear. Paraquat
damages farmworkers’ respiratory system, their kidneys, and their eyes, which
the EPA concedes. A National Institutes of Health study found
that workers who have used it are 2.5 times more likely to develop Parkinson’s,
and a study published
earlier this year found that people who live near the fields where paraquat is
sprayed also experience increased Parkinson’s disease risks. Yet the EPA
reauthorized the widespread use of paraquat without addressing its neurological
risks.
Thousands of people have stories of
contracting Parkinson’s after being exposed to paraquat. Take Lori Phillips,
for example, a 67-year-old woman who grew up on a small family farm in New
York. “I can still remember the smell of the crops being sprayed by my bedroom
window,” she says. “This was in the early 1960s, about the time that paraquat
was invented and put on the market.”
Fast forward 50 years and Phillips’ mother,
brother, and uncle were all diagnosed with Parkinson’s. She and her brother
were tested for the genes linked to Parkinson’s, and neither had any of them,
suggesting environmental factors were at play.
Despite not always having control
of her arms, which hang rigidly at her side, or her feet, which shuffle when
she walks, Phillips stays active as best she can. But the old Phillips — who
could run marathons and type 120 words a minute at work, was an avid sewer, and
planned to travel throughout retirement – is gone.
People tend to know about the
slurred speech and trouble with movement that characterize Parkinson’s. But
less well-known is the link between Parkinson’s and depression as the disease
drains the brain of dopamine.
“Sometimes the medicine works and
sometimes it doesn’t,” she explains. “It affects cognitive thinking. It affects
your speech. You get constipated. You get dementia very easily. You get
depressed.”
Then there’s the financial stress.
There’s no generic version of Ongentys, the medicine Phillips takes; a 90-day
supply costs $1,900. And that’s just one pill, before you get to the others and
all the supplements that health insurance won’t cover. To get by, Phillips,
like many others, gets grants from non-profit organizations that help them pay
for medicine.
But there’s no guarantee how long
that will go on. And because of her Parkinson’s, Phillips does not qualify for
long-term care insurance, which makes her future precarious at best.
Earthjustice is fighting to press
the EPA to do what it should have done years ago – to ban paraquat. But we’re
up against chemical companies with deep pockets who will go to great lengths to
bury the evidence of paraquat’s harm. And the EPA’s latest analysis of paraquat
continues to overlook the overwhelming evidence linking the herbicide to
Parkinson’s disease. The EPA needs to hear from people like you that it
should ban this deadly chemical. This month marks the start of 60-day comment
period where people can make their feelings known to the EPA.
What is
paraquat? What are paraquat’s health harms?
It’s an herbicide used on
farms to stop weeds from growing. It’s quite good at killing weeds – but it’s
lethal for people too. And it disrupts normal neurological functioning. It’s
been linked to a host of serious diseases in humans, including Parkinson’s and
kidney disease.
The risks skyrocket the
longer you’re exposed to it, which puts farmworkers at great risk. It can also
cause migraines, and dizziness on a day-to-day basis for people who handle it.
Who faces the greatest risks
from paraquat?
Scientific
research has not found that there is a health risk to people who eat food
treated with paraquat at the levels approved by the EPA. But the EPA has found
that the approved use of paraquat presents serious health risks to farmworkers,
and studies have shown harm to the communities surrounding the farms where
paraquat is sprayed. Thousands of people across the world have also died from
paraquat ingestion, since one small sip is enough to kill and there is no known
antidote.
Despite
the dangers of paraquat and the existence of safer alternatives on the market,
paraquat’s use doubled between 2012 and 2018.
Why is paraquat still on the market?
Paraquat
has already been banned in more than 50 countries, including all the countries
in the European Union. The two places where it’s actually made — the UK and
China – ban its use. But here in the U.S., chemical manufacturers still have a
good deal of leverage in the political process. So they put pressure on
regulators and put up their own experts to sew doubt over the scientific
evidence linking paraquat to Parkinson’s disease. Syngenta, the company that
manufactures paraquat, continues to sell the deadly chemical in the U.S.,
Australia, New Zealand, Japan, and Indonesia
Syngenta
denies the evidence linking paraquat to Parkinson’s and other health harms. An investigation by
The Guardian and the New Lede in 2022 showed that Syngenta suppressed evidence
of paraquat’s presence in the brain, withheld key data related to paraquat’s
harms from the EPA, and fought to keep scientists who had documented the
connection between paraquat and Parkinson’s disease off an influential EPA peer
review panel.
What have you heard from people exposed to paraquat?
“We’d go
out spraying and get it on our skin. Our boots were soaked in the chemical. I
am very athletic, played football in college. Then I noticed at the age of 37,
my gait was foreshortened on the right side, badly so I could barely get across
a parking lot.”
– John Kelly, who worked for a lawn
company spraying paraquat from ages 13 to 16
“My life
is dramatically changed. I have slowness of movement. I don’t qualify for
long-term care insurance if I have to go into a long-term care facility. How do
you even survive when you’ve got $3000 a month in medicine?”
– Lori Phillips, person with Parkinson’s
“He cannot
walk unassisted without falling – the problem now is the constant falling. He
has cut his head open and had 10 metal stitches in his head. He ended up having
a blood clot in his arm from a fall. Those kinds of things happen. He’s on many
medications. His pillbox contains 25 pills just to function. One of the
medications is for hallucinations he has had in the past – if we had to pay the
out-of-pocket, even with insurance, it would be over $2000 a month. “
– Irene Miller, a support group leader
who cares for her husband who has Parkinson’s
What is Earthjustice’s role in fighting to get paraquat banned?
We
sued the EPA when the agency renewed the registration for the chemical,
reauthorizing its widespread use for another 15 years. Our clients include
Farmworker Association of Florida, Farmworker Justice, Alianza Nacional de
Campesinas, California Rural Legal Assistance Foundation, The Michael J. Fox
Foundation for Parkinson’s Research, Pesticide Action Network North America,
Center for Biological Diversity, and Toxic Free North Carolina. Our
lawsuit claims that the EPA violated the Federal Insecticide, Fungicide and
Rodenticide Act (FIFRA) by failing to adequately consider the risks of
Parkinson’s disease, ignoring key exposure pathways, and leaving farmworkers
and agricultural communities exposed to unreasonable risks.
In
response to our suit, the EPA has agreed to take a new look at the science and
let the public weigh in. This is a crucial period to show the EPA that the
paraquat presents unacceptable health risks and must be banned.
What could happen next?
In
early 2025, the EPA will finalize its reassessment on paraquat’s risk, making
its decision based partly on public input. We are pressing the EPA to issue an
outright ban of paraquat, as dozens of other countries have already done. It
remains to be seen whether the United States will join them. Earthjustice
members have an important role to play because we know the EPA is hearing from
the chemical lobby. They need to hear from us too.
Tell the EPA to ban paraquat now.
