Can somone please back-up or debunk this "fact" about plastic and Microwaves?

Plastic Wrap Toxins. 
Author/s: Jule Klotter 
Issue:  Jan, 2001 

As a seventh grade student, Claire Nelson learned that 

di(ethylhexyl)adepate (DEHA), considered a carcinogen, is found in
plastic wrap. She also learned that the FDA had never studied the
effect of microwave cooking on plastic-wrapped food. Claire began to
wonder: “Can cancer-causing particles seep into food covered with
household plastic wrap while it is being microwaved?”

Three years later, with encouragement from her high 
school science teacher, Claire had an idea for studying the effect of 

microwave radiation on plastic-wrapped food, she did not have the
equipment.

Eventually, Jon Wilkes at the National Center for  Toxicological 

Research in Jefferson, Arkansas, agreed to help her.

The research center, which is affiliated with the 
FDA, let her use its facilities to perform her experiments, which 

involved microwaving plastic wrap in virgin olive oil.

Claire tested four different plastic wraps and "found not just the 

carcinogens but also xenoestrogen was migrating [into the oil]…"
Xenoestrogens are linked to low sperm counts in men and to breast
cancer in women.

Throughout her junior and senior years, Claire made 
a couple of trips each week to the research center, which was 25 miles 

from her home, to work on her experiment.

An article in Options reported that "her analysis found that DEHA was 

migrating into the oil at between 200 parts and 500 parts per million.

The FDA standard is 0.05 parts per billion." Her summarized results 

have been published in science journals. Claire Nelson received the
American Chemical Society’s top science prize for students during her
junior year and fourth place at the International Science and
Engineering Fair (Fort Worth,Texas) as a senior.

On Channel 2 (Huntsville, AL) this morning they had 
a Dr. Edward Fujimoto from Castle Hospital on the program. He is the 

manager of the Wellness Program at the hospital. He was talking about
dioxins and how bad they are for us. He said that we should not be
heating our food in the Microwave using plastic containers. This
applies to foods that contain fat. He said that the combination of fat,
high heat and plastics releases dioxins into the food and ultimately
into the cells of the body.

Dioxins are carcinogens and highly toxic to the cells of our bodies. 

Instead, he recommends using glass, Corning Ware, or ceramic containers
for heating food. You get the same results without the dioxins. So such
things as TV dinners, instant saimin and soups, etc., should be removed
from the container and heated in something else. Paper isn’t bad but you
don’t know what is in the paper. Just safer to use tempered glass,
Corning Ware, etc.

He said we might remember when some of the fast food restaurants moved 

away from the foam containers to paper. The dioxin problem is one of the
reasons.

To add to this: Saran wrap placed over foods as they are nuked, with 

the high heat, actually drips poisonous toxins into the food! Use a
paper towel!!

You might want to pass this on to your friends....I just did!! 

Does anyone know if there is any truth to this?

[Chronos]

Snopes says there’s some truth to this, but they aren’t too worried. It’s only some brands of plastic wrap that does this, and the ones labelled “microwave safe” are.

Microwaving Plastic Releases Cancer-Causing Agents

Apparently, both of these people did what it says they did, but neither is particularly reliable research. Plastic films labeled “microwave-safe” have probably been tested and found safe; the substances named have never actually been shown to cause any harm to humans; the actual use of these materials doesn’t necessarily correspond to the protocol used in the experiments.

[bernse]

Thanks!

Snopes is my friend. I should have checked there first.

[Broomstick]

He said we might remember when some of the fast food restaurants moved away from the foam containers to paper. The dioxin problem is one of the reasons.

I thought they moved from foam to paper because of “environmental concerns” - people perceive paper as recyclable (which it is, even though most of it isn’t recycled). In fact, dixons are formed during modern paper and paper pulp manufacture.

When you buy a dish to heat things in the microwave look on the box. You want to see “microwave safe” on it. That means the plastic, if it is plastic, is OK for the nuke oven. If it doesn’t say that, assume it’s not a good idea. This will probably solve 99.99% of the problem.

Consumer Reports did a study on this and also found using plastic wrap was safe.

Consumer Reports did a study on this and also found using plastic wrap was safe.

Did they do long term toxicity studies ? What other things did they not check for ? Did they actually stew the plastic wrap in superheated oil, and then check the smoking residue for bad stuff, or did they assume that everyone tosses their cooking mistakes ?

Actually, a local television news recently showed a debunking of this. I attend UC Davis so I paid a bit of attention to the news segment in question.

First: The university asserted it has not conducted such research.
Second: The “researcher” named in the orginal hoax, according to the University rep in the news segment, is not employed nor a student at UC Davis.
Third: The segment closed with one of the people who actually is a researcher at the University “nuking” his plastic wrapped meal and consuming it on camera.

In short, it’s BS, judging by the madeup “researcher” at our local university inserted into the story to give it credence. You’d think that the hoaxter (hoaxster?) would’ve used the school’s website (http://www.ucdavis.edu) to check the directory and copy a real name!

[Tranquilis]

Ah, but a real person could be contacted, allowing even easier debunking.

[Arkcon]

OK, so I’ve gone and necroed a decade and a half old thread, and even changed the title in my bump. But I want to know … how does her story end?

OK, back in 2000, this story was burning up the newsfeeds, and Snopes and The Straight Dope were all we had to debunk it with. Tiny little peeps of reason in the wild. Now this story is immortal – you never ever microwave anything in plastic or you’ll die from horrible belly explosion, researchers say, is what I always hear. I always shoot back, look it up, you’re quoting a 7th graders project, not a research project. The FDA long ago decided what to approve as a food safe container.

Pfft. As if. Of course the male-dominated, government sanctioned, fat cats just want to preserve the status quo. Even a 7th grader knows you think as much with your heart as with your brain when conducting science. Well, that’s the response I tend to get.

This is pretty much the story of the Mpemba effect – how warmer liquids freeze first. People still study it, and people still argue about it. But Mpemba himself isn’t now a theoretical physicist, he’s a game warden. His initial observations are no less valid, but that doesn’t make the science any better either.

So, Claire Nelson: tenured university theoretical chemist? analytical chemist for a major company? Eco-blogger? Paralegal in a consumer advocate legal firm? Account executive in a hometown insurance company? What?
