In our ongoing reporting we move on from pizza to organic food.
From a link offered in John Stossel's excellent post Organic Hype, note the below excerpts from his latest book, "Myths, Lies and Downright Stupidity:"
MYTH: Pesticide residues in food cause cancer and other diseases.
TRUTH: The residues are largely harmless.
Ames laughs at the claims of chemically induced cancers, and he should
know-he's the one who invented the test that first frightened people
about a lot of those chemicals. It's called the Ames Test, and its
first use in the 1970s raised alarms by revealing there were
carcinogens in hair dye, and in the flame retardants in children's
pajamas. Ames helped get the chemicals banned.
Before the Ames Test, the traditional way to test a substance
was to feed big doses of it to animals and wait to see if they got
cancer or had babies with birth defects. But those tests took two to
three years and cost $100,000. So Dr. Ames said, "Instead of testing
animals, why not test bacteria? You can study a billion of them on just
one Petri dish and you don't have to wait long for the next generation.
Bacteria reproduce every twenty minutes."
The test proved successful. It was hailed as a major scientific
breakthrough, and today, the Ames Test is one of the standards used to
discover if a substance is carcinogenic.
But after getting the hair dye and the flame retardants banned,
Dr. Ames and other scientists continued testing chemicals. "People
started using our test," he told me, "and finding mutagens
everywhere-in cups of coffee, on the outside of bread, and when you fry
your hamburger!"
This made him wonder if his tests were too sensitive, and led
him to question the very bans he'd advocated. A few years later, when I
went to a supermarket with him, he certainly didn't send out any danger
signals.
DR. AMES Practically everything in the supermarket, if you
really looked at it at the parts per billion level, would have
carcinogens. Vegetables are good for you, yet vegetables make toxic
chemicals to keep off insects, so every vegetable is 5 percent of its
weight in toxic chemicals. These are Nature's pesticides. Celery,
alfalfa sprouts, and mushrooms are just chock-full of carcinogens.
STOSSEL Over there it says "Organic Produce." Is that better?
DR. AMES No, absolutely not, because the amount of pesticide
residues-man-made pesticide residues-people are eating are actually
trivial and very, very tiny amounts! We get more carcinogens in a cup
of coffee than we do in all the pesticide residues you eat in a day.
In a cup of coffee? To put the risks in perspective, Ames and
his staff analyzed the results of every cancer test done on rats and
mice. By comparing the dose that gave the rodents cancer to the typical
exposure people get, they came up with a ranking of the danger.
Pesticides such as DDT and EDB came out much lower than herb tea,
peanut butter, alcohol, and mushrooms. We moved over to the mushrooms
as the cameras continued to roll, and Dr. Ames put his mouth where his
convictions were.
DR. AMES One raw mushroom gives you much more carcinogens than any polluted water you're going to drink in a day.
STOSSEL So you're saying we shouldn't eat fresh produce?
DR. AMES No. Fresh produce is good for you! Here, I'll eat a raw mushroom even though it's full of carcinogens.
Dr. Ames is widely respected in the scientific community, but he
is not on many journalists' electronic Rolodexes. He's the real deal,
and no help at all if you're looking for screaming headlines.
