The Teflon Controversy......
Is Your Cookware Poisoning You?
For over 40 years scientists have
known that the fumes from hot non-stick surfaces can
kill birds such as canaries. So just how dangerous are
they to humans?
Several studies have been conducted into
health concerns surrounding Teflon, the coating invented
and patented by DuPont. The results have been
disturbing, if somewhat
inconclusive.
While the lethal effect on birds is well
documented and not in dispute, much of the other
evidence tends to be anecdotal at best. And some of it
is downright
confusing.
For example, the chemical perfluorooctanoic acid
(PFOA) is usually cited as the villain of the
piece and the root cause of the illnesses that have
allegedly appeared in some users. However DuPont claims
Teflon doesn't contain this chemical, although it is
used in the manufacturing
process.
Whatever the truth of that may be, it’s
certainly accurate to say that there have been a number
of health issues emerging in the community immediately
adjacent to the DuPont factory in Parkersburg, West Virginia;
more about that
later.
There also seems to be some disagreement
among authorities as to the temperatures at which the
bird-lethal fumes are given off. These are quoted as
ranging from 285°F to 475° and
more.
Since both these figures are well within
the smoke points of edible oils such as avocado and
safflower, keeping your budgie in or near the kitchen is
definitely not good for his
health.
But what about your
health?
Human 'victims' have complained of
flu-like symptoms, some leading to respiratory
complications, after using non-stick cookware. Some
reactions have been reported as
"severe"".
At least one report suggests that the
fumes may be cancer inducing after prolonged exposure,
although none suggest that Teflon itself is harmful if
swallowed.
If the fumes are harmful to humans, then
there is much more to consider than just kitchen items.
Some brands of light bulb, portable heaters and even
Gore Tex clothing are all produced using PFOA, the same
reactive agent used in the case of
Teflon.
Not surprisingly, DuPont denies there is
any problem; but this hasn't prevented the company from
paying out millions of dollars in compensation, not only
to their employees but to 50,000 people living in the
vicinity of the Parkersburg factory. You have to ask
yourself "why?".
Complaints have included accusations of
water pollution, high infant mortality rates and a
greater than normal incidence of cancer among the local
population. DuPont has never admitted liability in any
of these cases.
While the jury still seems to be out on
the safety or otherwise of Teflon in the home, even
DuPont's own experts advise caution when using non-stick
items, particularly with regard to high cooking
temperatures.
And this is something you can rely on:
when Teflon and similar coatings are heated to a certain
point, fumes are given off. These fumes will kill pet
birds that inhale them. It’s therefore reasonable to
suppose that other forms of life may also be at
risk.
