I'm reminded of the 1950's...TV newscasts
showing clouds of DDT sprayed on a clueless public, compromising their
health and contaminating the environment for decades to come, as Rachel
Carson writes "Silent Spring." But the time is now, other toxic
pesticides have joined the ranks in our wayward war against mosquitoes,
and the Rachels of today are drowned out by a media rushing to sound the
alarm, rather than report the news. And the news is - pesticides pose
a much greater health hazard than the West Nile virus.
DEET, Anvil, and other toxic pesticides are aggressively promoted to
protect the public from a mosquito bite that appears to be,
statistically, less dangerous than a dog bite or bee sting. And the CDC
seems to agree. On its website it says, "Human illness from West Nile
virus is rare, even in areas where the virus has been reported. The
chance that any one person is going to become ill from a mosquito bite
is low."
Since 1999 only a handful of deaths per year have been associated
with West Nile, even though the virus has been found in 33 states.
The fact that this "health crisis" has been exaggerated, and that
chemical spraying is usually the least effective yet most toxic way to
control mosquitoes, has deterred some state officials, but not others.
The New York State Health Department backed away from recommending
wholesale spraying after finding that more people got sick from the
pesticides than from the virus. However, Louisiana has just asked for
$17 million in federal aid, and Mississippi is following suit. There's
no word yet on how the money is to be allocated, but rest assured the
pesticide companies stand to benefit.
Meanwhile, some citizen groups are taking matters into their own
hands. The No Spray Coalition is suing New York City to stop pesticide
spraying in their neighborhoods.
There's a good deal of information on government and other websites
about the toxic effects of pesticides, but a comprehensive picture of
the specific pesticides and issues involved in the West Nile campaign is
well laid out in a report called "Overkill: Why Pesticide Spraying for
West Nile Virus May Cause More Harm Than Good" by the Maine
Environmental Policy Institute (MEPI) and the Toxics Action Center.
In short, they report that these pesticides offer a toxic
legacy: short- and long-term respiratory problems, immune and nervous
system disruption, cancer, and reproductive and learning disorders. That
covers just about everything you'd never want to get.
The "Overkill" report also emphasizes the association between outdoor
pesticide sprays and neurological damage, stating, "A report of
pesticides and childhood brain cancers published in Environmental Health
Perspectives (a publication of the National Institutes of Health)
revealed a strong relationship between brain cancers and pyrethroids
used to kill fleas and ticks." Anvil, a pyrethroid, is a popular
pesticide used by state agencies to control mosquitoes.
The use of DEET in mosquito repellents is extremely troubling. DEET
has been associated with seizures and several cases of toxic
encephalopathy (encephalitis) in children, including three deaths,
according to the Extension Toxicology Network at Cornell University.
The battle against West Nile is supposed to prevent a virus that can
cause encephalitis. It appears the cure can cause the disease. That
would be ironic, if it weren't so tragic.
Dr. Mohamed Abou-Donia, a research scientist at Duke University
Medical Center, whose studies have established a link between DEET and
neurological damage in animals, warns parents in a recent Environmental
News Service article, "Never use insect repellents on infants, and be
wary of using them on children in general. Never combine insecticides
with each other or use them with other medications. Even so simple a
drug as an antihistamine could interact with DEET to cause toxic side
effects. Don't spray your yard for bugs and then take medications. Until
we have more data on potential interactions in humans, safe is better
than sorry."
Meanwhile, state and federal agencies, including the Environmental
Protection Agency (EPA) and the Centers for Disease Control (CDC), are
encouraging the public to use mosquito repellents containing DEET.
Although the CDC warns parents to avoid applying repellent on children
less than 2 years old, the EPA and other state agencies are not giving
that caution. The EPA instead advises, "Do not allow children to handle
the products, and do not apply to children's hands. When using on
children, apply to your own hands and then put it on the child."
Have these people ever met a child? Children touch everything and
everybody, including themselves. And then they put their pudgy little
fingers directly into their mouths.
While the battle plan's objective is to target the mosquitoes that
carry West Nile, the strikes won't be 'precision' and the collateral
damage could be vast. Pesticides and larvicides can impact fish,
insects, animals, and humans. And although the public has been told to
lather up with DEET, spray pesticides, and eliminate standing water,
little has been said about using select plants, birds, bugs, fish, and
amphibians - gifts of nature that help control mosquitoes.
It seems we're traveling in a deadly circle. Spraying for West Nile,
while we're gassing ourselves. Falling for a health scare, when the real
scare is the alleged cure. And the real cure can be found in the natural
world we're attacking.
