Have a weak stomach? Don't read any further. OK, you've been warned.
Did you know that you're eating insects, rat hair, rat excrement and
insect fragments every day? And that it's OK with the U.S.
government?
It's true. The Food and Drug Administration sets "food defect action
levels," the maximum levels of natural or unavoidable defects in foods
-- like how many insects or rat hairs are permissible.
WHY ALLOW ANY DEFECTS IN FOODS?
The
action levels were created because it's "economically impractical to
grow, harvest or process foods that are totally free of safe, naturally
occurring, unavoidable defects," says Barry Swanson, Ph.D., professor
of food science and nutrition at Washington State University in
Pullman.
In fact, the FDA action level defect guidelines
say: "The alternative to establishing natural defect levels in some
foods would be to insist on increased utilization of chemical
substances to control insects, rodents and other natural contaminants.
The alternative is not satisfactory because of the very real danger of
exposing consumers to potential hazards from residues of these
chemicals, as opposed to the aesthetically unpleasant but harmless
natural and unavoidable defects." In other words, to have no defects,
you would have to use more chemicals, and foods would be less healthy.
EATING INSECTS
It's been estimated by an Ohio University fact sheet that we actually eat 1 to 2 pounds of insects each year, unintentionally.
"They're
actually pretty healthy," says Philip Nixon, Ph.D., an entomologist at
the University of Illinois. Insects are a regular part of a balanced
diet throughout most of the world, with the exception of Europe and
North America. They have nutrients, are high in protein and low in fat.
And, "If we were more willing to accept certain defect levels such as
insects and insect parts, growers could reduce pesticide usage. Some of
the spraying that goes on is directly related to the aesthetics of our
food," adds Nixon.
ARE THESE 'DEFECTS' DANGEROUS?
"Not at all," says Manfred
Kroger, Ph.D., a professor of food science at Pennsylvania State
University. They're basically processed filth, meaning they have been
sterilized. "Let's face it," he says, "much of our food comes from
nature, and nature is not perfect." And that means it has some level of
contamination (mold, insects, rodent hairs or excrement). However,
"This is more about how the food looks and what people think than about
health," says Stephen Pintauro, Ph.D., a professor of food science at
the University of Vermont.
IS ORGANIC THE ANSWER?
"Organic
food is probably worse," says Kroger. "Think about it. When you're
using raw animal waste as fertilizer and less pesticides, it's much
more difficult to keep organic foods free of defects."
WHICH FOODS ARE AFFECTED?
These
defect guidelines cover any foods exposed to biological contamination,
as well as foods attractive to insects or microbes that the consumer
may not see (like popcorn, tomato products, spices, raspberries,
blackberries, strawberries, peppers, mushrooms, cornmeal, tree nuts and
dry legumes). The list compiled by the FDA includes about 105 foods.
RANDOM FOODS
When
you look at the list, it seems almost random. But according to the FDA,
these foods are picked "whenever it is necessary and feasible to do
so," which basically translates to the foods that come up with problems
most frequently. Does this mean that other foods don't have defects?
No. "Almost all foods have defects. In fact, the only food that might
have virtually none is infant formula, because of the way it's
processed," according to Pintauro.
ONLY 10 PERCENT
"Action
levels" are the point at which the FDA starts an investigation and
decides what action is warranted. But if these are the upper limits
allowed by law, what can we expect to find in our food? Well, that
depends -- if you ask the FDA, it's about 10 percent of the action
levels, but other experts argue it could be as high as 40 percent.
THE FOOD DEFECT ACTION LEVELS
Here is a small sampling of foods from the guide. You can view the list in its entirety on the FDA Web site at http://vm.cfsan.fda.gov/~dms/dalbook.html.
PEANUT BUTTER
Defect: Insect and rodent filth.
Action level: An average of 30 or more insect fragments and one or more rodent hairs per 100 grams.
Example: In every 18-ounce jar of peanut butter, there can be as many as 150 insect fragments and five rodent hairs.
CHOCOLATE
Defect: Insect and rodent filth.
Action level: An average of 60 or more insect fragments and one or more rodent hairs per 100 grams.
Example:
A typical chocolate bar is about 60 grams, or 2 ounces. It could have
as many as 36 insect fragments and about half a rodent hair and still
be sold in supermarkets.
MACARONI AND PASTA
Defect: Insect and rodent filth.
Action level: An average of 225 or more insect fragments and 4.5 rodent hairs per 225 grams (an 8-ounce serving).
WHEAT FLOUR
Defect: Insect and rodent filth.
Action level: An average of 75 or more insect fragments and one or more rodent hairs per 50 grams.
Example: A 2-pound bag can have as many as 1,344 insect fragments and 18 rodent hairs.
FROZEN BROCCOLI
Defect: Insects and mites.
Action level: An average of 60 or more aphids and/or thrips (insects) and/or mites per 100 grams.
Example:
A 10-ounce box of frozen broccoli can have no more than 168 insects or
mites. (Aphids and thrips are plant-sucking insects.)
CANNED CITRUS FRUIT JUICES
Defect: Mold, insects and insect eggs.
Action
level: Ten percent average mold count or more, and five or more fruit
fly and other fly eggs or one or more maggots per 250 milliliters.
Example: No more than five fruit fly or other eggs or one maggot per 8-ounce glass.
TOMATO PASTE, PIZZA AND OTHER SAUCES
Defect: Fruit flies and maggots.
Action
level: An average of 30 or more fly eggs, or 15 or more fly eggs and
one or more maggots, or two or more maggots per 100 grams.
Example: If a typical jar is 26 ounces, there can be as many as 220 eggs per jar.
GROUND PEPPER
Defect: Insect filth and rodent filth.
Action level: An average of 475 or more insect fragments and two or more rodent hairs per 50 grams.
Example: In every teaspoon, you could find as many as 27 insect fragments and about a tenth of a rodent hair.
SPINACH, CANNED OR FROZEN
Defect: Insects and mites.
Action
level: An average of 50 or more aphids, thrips and/or mites OR 2 or
more 3 millimeters or longer larvae and/or larval fragments OR spinach
worms (caterpillars) whose aggregate length exceeds 12 millimeters
present in 24 pounds OR an average of eight or more leaf miners of any
size per 100 grams OR an average of four or more leaf miners that are 3
millimeters or longer per 100 grams.
Example: A 10-ounce box of frozen spinach can have no more than 142 insects or mites or 22 caterpillars.
SAUERKRAUT
Defect: Insects.
Action level: An average of more than 50 thrips per 100 grams.
Example: Two tablespoons of sauerkraut can contain no more than 15 thrips.
CHERRIES, BRINED AND MARASCHINO
