Farm Workers Bear the Brunt of
Pesticide Poisoning
August 26, 2015
By Dr. Mercola
Worldwide, more than 5 billion pounds of pesticides are
sprayed onto crops each year,1
and more than 75 percent of the US population has detectable
levels of organophosphates (OPs), which are among the most
commonly used insecticides on American farms.
Your diet is one of the most likely routes of exposure –
unless you're a farmer or live near an agricultural area. For
farm workers, their children, and those who live in farming
communities,
pesticide exposure is a fact of life, but one that puts
their health in serious jeopardy.
The next time you’re at the grocery store deciding between
organic or conventional strawberries, realize that the decision
affects far more than your own health. For the farm workers
spraying those fields, and the children living and going to
school near them, the pesticide exposure will be far greater
than it will be for you.
Most of the farm workers are forced to work in these
hazardous conditions in order to feed their own families, but
that’s because pesticide-laden conventional produce is still
accepted and dominates the market.
Ultimately, a shift to an organic, more sustainable food supply
would make all the difference – not only for the families that
eat the food but also for the farm workers who grow it.
Farm Workers Are Exposed to High Levels of Pesticides
A recent report from Farmworker Justice highlighted just how
bad the pesticide exposure has become.2
Up to 20,000 farm workers are poisoned by pesticides each year,
according to data from the US Environmental Protection Agency
(EPA).
The actual number is likely far higher, as many of the
workers may not seek medical care or may be misdiagnosed if they
do seek treatment. There is also no coordinated national
incident reporting system to track such exposures. Despite this,
pesticide exposures cause farm workers more chemical-related
injuries and illnesses than any other workforce nationwide.
According to the report:3
“Farmworkers are exposed to pesticides in a variety
of ways. Workers who perform hand labor tasks in treated
areas risk exposure from direct spray, aerial drift, or
contact with pesticide residues on the crop or soil.
Workers who mix, load, or apply pesticides can be
exposed to pesticides due to spills, splashes, and
defective, missing, or inadequate protective equipment.
Even when not working in the fields, farmworker
families, especially children, are also at risk of elevated
pesticide exposure. Workers bring pesticides into their
homes in the form of residues on their tools, clothes,
shoes, and skin. They inadvertently expose their children
through a hug if they cannot shower after work.
The close proximity of agricultural fields to
residential areas results in aerial drift of pesticides into
farmworkers’ homes, schools, and playgrounds. Some
schoolyards are directly adjacent to fields of crops that
are sprayed with pesticides.
Pesticide exposure is an unavoidable reality for
farmworkers and their families because pesticides are in the
air they breathe, the water they drink, the food they eat,
and the soil they cultivate.”
Health Impacts of Pesticide Exposures
There are both short- and long-term effects that occur from
pesticide exposures. In the short-term, exposures can lead to
rashes, blisters, stinging eyes, blindness, nausea, dizziness,
headaches, coma, and death.
Some effects are delayed, however, and may not be immediately
apparent. Such long-term effects include infertility, birth
defects, endocrine disruption, neurological disorders, and
cancer.
There are about 2.5 million farm workers in the US, about 60
percent of whom live in poverty. Most of them lack legal work
authorization, which means they’re unlikely to report violations
of workplace safety, abuse of protective regulations, or even
seek medical attention for potential poisonings.
Further, some symptoms of pesticide exposure resemble the
flu, so many workers aren’t aware of the exposure. There are
also language barriers to factor in and the risk of employer
retaliation if a farm worker challenges unsafe pesticide
practices or seeks medical treatment for pesticide exposures.
According to the report:4
“Rural and agricultural communities have been found
to experience higher rates of leukemia, non-Hodgkin
lymphoma, multiple myeloma, and soft tissue sarcoma, as well
as cancers of the skin, lip, stomach, brain, and prostate.
Workers who reported farm work as their primary
occupation suffered elevated risks for prostate cancer,
esophagus cancer, and oral cavity cancers. …
Pesticide exposure is attributed to higher rates of birth
defects, developmental delays, leukemia, and brain cancer
among farmworker children.”
‘Absolute Proof’ of the Damaging Effects of Pesticides on
Children’s Brains
Because the effects of pesticide exposure aren’t always
immediate, it can be difficult to tie them directly to the
health problems they cause. However, the CHAMACOS Study showed
that very small amounts of pesticides may be harming kids’
brains.
It followed hundreds of pregnant women living in Salinas
Valley, California, an agricultural mecca that has had up to a
half-million pounds of organophosphates sprayed in the region
per year.
The children were followed through age 12 to assess what
impact the pesticides had on their development.5
It turns out the impact was quite dramatic, and mothers'
exposure to organophosphates during pregnancy was associated
with:6
- Shorter duration of pregnancy
- Poorer neonatal reflexes
- Lower IQ and poorer cognitive functioning in children
- Increased risk of attention problems in children
Research published, ironically, the same day as the CHAMACOS
study, also found that prenatal exposure to chlorpyrifos
(Dursban, a pesticide once used to control cockroaches in inner
cities) was associated with lower IQs and poorer working memory
in three-year-olds.7
A senior scientist at the Natural Resources Defense Council,
who is now an official at the California Environmental
Protection Agency (EPA) said the combination of studies come
"about as close as I can imagine to absolute proof" of the
damaging effects of pesticides on children's brains.8
It is this cumulative effect of numerous chemicals,
particularly to developing children, that likely poses the
greatest risks of all. Brenda Eskenazi, chief investigator of
the CHAMACOS study, noted:9
"The other thing we don't know about is the combined
effect of exposures … Throughout the course of a day, people
may eat several different types of produce, each of which
may bear traces of one or more pesticides. They encounter
other types of chemicals as well — from antibacterials in
soaps, to plasticizers in foodware, to flame retardants in
the furniture… By day's end, you've got a combination of
chemicals and an unknown level of risk."
This level of risk is heightened significantly among the
children of farm workers who also live and go to school
in close proximity to the heavily sprayed fields…
Many Farm Workers Are Unaware of the Risks They’re Facing
A federal law known as the Work Protection Standard (WPS)
requires pesticide safety training for farm workers,
notification of pesticide applications, and emergency medical
assistance. However, it is weakly enforced and many workers only
watch a 20-minute video about pesticide exposure symptoms once
every five years.
Pesticide applicators are at heightened risk as well, since
many speak Spanish but the pesticide labels (including the
safety information and health risks) are written in English.
Available safeguards, such as requiring pesticide applicators to
sit in an enclosed cab with a ventilation system (as opposed to
in the open cab of a truck) are not often used or required.
Many of the workers are simply not aware of the health risks
posed by pesticides and are often unaware when exposures occur.
Medical monitoring of workers who regularly handle neurotoxic
pesticides, which allows overexposures to be identified before
there is irreversible harm, has been shown to help reduce the
risks – but it’s not required.
No-spray buffer zones around area homes, schools, and parks
could help to protect workers and their families from aerial
pesticide drifts… but perhaps the more pressing question is why
we continue to use such toxic chemicals on agricultural fields
in the first place.
EPA Botches Pesticide-Spraying Settlement
In 1999, a civil-rights complaint was filed against the
California Department of Pesticide Regulation. Farm workers in
the strawberry fields near Oxnard, California were concerned the
pesticides sprayed on the fields were contaminating nearby
schools. And the complaint alleged that agricultural pesticides
were being used more heavily around schools with mostly minority
student populations.
After an investigation, the US Environmental Protection
Agency (EPA) released its preliminary finding and, in a first
and only decision, ruled it a case of discrimination and settled
with the state of California. The EPA touted this as a victory
for the farm workers… but there were just a few
problems… For starters, the EPA took more than a decade
to issue their finding – in 2011. By that time, the children in
the schools in question had long since graduated and some had
even started families of their own. The terms of the settlement
were also far from “victorious.”
The California Department of Pesticide Regulation, in
exchange for admitting no wrongdoing, agreed to put an
additional air monitor near a school. And the original
complainants, who are supposed to be a part of the process,
weren’t notified of the EPA’s discrimination finding until after
the settlement with the state was announced; they had no input
whatsoever.
EPA Ignores Ongoing Spraying of Toxic Chemicals Near Schools…
The complainants tried to get the EPA to reopen the
settlement negotiations, but the agency refused. One of them
even filed a lawsuit against the EPA for the way it handled the
investigation and settlement, but it was dismissed in 2014 (an
appeal is pending). One of the main atrocities of the case is
that it had mentioned, in 1999, the regular use of the fumigant
methyl bromide, which was linked to neurological effects and
lung and kidney damage. In 2005, the US agreed to phase the
chemical out, but farmers were allowed to continue to spray it
on strawberries until 2015.
By the time the EPA’s decision was made, methyl bromide was
already being widely replaced… but the EPA didn’t factor in the
chemicals being used to replace it. So while methyl bromide was
certainly less of an issue, replacement chemicals, like 1,3-D, a
probable carcinogen, should have been investigated – but were
not. As reported by The Center for Public Integrity:10
“The settlement agreement didn’t take into account
the chemicals that would spring up to replace methyl
bromide. In fact, it focused only on the use of methyl
bromide between 1995 and 2001 — the years leading up to when
the case was filed, and later accepted for investigation.
The EPA said at the time that it looked at methyl bromide
because the chemical was specifically mentioned in the
complaint. [Brent] Newell [legal director for the Center on
Race, Poverty, and the Environment, which is one of the
agencies that filed the complaint], called it a dereliction
of duty.
‘I still do not know why EPA did not include the
fumigants that were replacing methyl bromide,’ he said. ‘…
Now, if they didn’t do it because they’re incompetent,
that’s a problem. If they knew about it and they decided to
deliberately restrict their investigation to only methyl
bromide, then that’s an even bigger problem. They would be
ignoring evidence that’s material to the investigation.’”
The Floriculture Industry Is Also a Danger to its Workers
It’s not only pesticide-laden produce that is putting
workers’ lives at risk; the cut flower industry is also among
one of the worst for pesticide exposures. A 1990 study looking
at the prevalence of reproductive problems in Colombian workers
exposed to pesticides while growing flowers found that workers
in the floriculture industry were exposed to 127 different types
of pesticides.11
According to the study:
"The prevalence rates for abortion, prematurity,
stillbirths, and malformations were estimated for
pregnancies occurring among the female workers and the wives
of the male workers before and after they started working in
floriculture, and these rates were related to various
degrees of exposure. A moderate increase in the prevalence
of abortion, prematurity, and congenital malformations was
detected for pregnancies occurring after the start of work
in floriculture."
Years later, a study published in the International
Journal of Environmental Health Research again assessed the
risk factors associated with pesticide exposure among farmers of
cut flowers — this time in the Philippines.12
Thirty-two percent of the workers reported pesticide-related
illnesses since starting work in the flower business, which
typically centered around their eyes, ears, nose, and throat.
The most commonly reported symptoms were weakness and fatigue,
muscle pain, chills and fever, blurred vision, dizziness, and
headache.
In a flower-growing region in Northern Ecuador, where female
employment in the industry is high, researchers found that
“prenatal exposure to pesticides – at levels not producing
adverse health outcomes in the mother – can cause lasting
adverse effects on brain development in children.” They conclude
that pesticide exposure may contribute to a "silent pandemic" of
developmental neurotoxicity in school-age children.13
By Eating Organic, You Can Help Shift the Agricultural Industry
Away from the Use of These Toxic Chemicals
Your best bet for minimizing health risks from
pesticide exposure is to avoid them in the first place by eating
organic as much as possible and investing in a good water
filtration system for your home or apartment. Alternatively, you
can try growing some of your own produce using organic methods
right in your own backyard. One of the benefits of eating
organic is that the foods will be free of
genetically modified (GM) ingredients – and this is key to
avoiding exposure to toxic
glyphosate.
Eating locally produced organic food will not only support
your family's health, it will also protect the environment from
harmful chemical pollutants and help shift the
agriculture industry away from conventional farming with the use
of toxic chemicals – a must for worker protection. As for cut
flowers, you can sometimes find organic cut flowers for sale at
farmer’s markets, flower shops, and health food stores, and
they’re also available to order online.
In the absence of organic certification, you can also look
for fair trade certification, as fair trade programs pay greater
attention to protecting worker's health and wellbeing, and
typically use fewer or less pesticides.
When consumers speak up, corporations listen. It’s because of
consumer demand that we’re seeing major chicken producers nixing
their use of antibiotics in chicken. If enough people demand
organic, pesticide-free food, and other goods, the agriculture
industry will have no choice but to listen. Finally, if you know
you have been exposed to pesticides, the lactic acid bacteria
formed during the
fermentation of kimchi may help your body break them down.
So including
fermented foods like kimchi in your diet may be a wise
strategy to help detox the pesticides that do enter your body.
