Dear Lou,
Is food irradiation good enough that we could theoretically go
back to having rare hamburgers, soft-boiled eggs and
unpasteurized milk? I miss all of those!
Carla
Dear Carla,
Let’s bond: I miss the hollandaise sauce at breakfast buffets,
homemade mayonnaise, and eggnog made from scratch. Oh, and I
miss raw chocolate chip cookie dough like the deserts miss the
rain.
The short answer to your question is no. If you’re going to
gamble, head for Vegas (or Reno—it’s nice there, too). No food
preservation method is good enough for you to take a completely
risk-free bite of any food, especially when it comes to
undercooked meat or egg products. Although irradiation can
vastly reduce pathogens, safe handling and cooking rules must be
heeded.
The longer and perhaps more interesting answer is this: Even if
irradiation (ionizing radiation) were effective enough to
completely sterilize our food, we might want look before we leap
when it comes to this technology.
As is my style, I’ll give you some pros and cons and let you
decide.
Irradiation pros:
• In an era marked by food recalls, deadly contaminations, and
food borne illnesses aplenty, irradiation could prevent illness
and deaths. Not only can it kill insects and parasites, it can
reduce or eliminate such nasty microorganisms such as E.coli,
Campylobacter, Listeria, and Salmonella.
• Irradiation is endorsed as safe by the Centers for Disease
Control, the World Health Organization, and the American Medical
Association. Say what you will, they’ve sure got a lot of people
there with fancy initials after their names. Here’s a
pro-irradiation video by the American Council on Science ....
• Irradiation does not leave traces of radioactive material in
food. (To the disappointment of nine-year-old boys everywhere,
you will not glow in the dark if you eat it.) According to a FAQ
by the
University of Wisconsin Food Irradiation Education Group,
“Irradiation by gamma rays, X-rays and accelerated electrons
under controlled conditions does not make food radioactive. Just
as the airport scanner doesn’t make your suitcase radioactive,
this process is not capable of inducing radioactivity in any
material, including food.”
• Irradiation proponents say that the nutritional value of the
food is largely unchanged. (They maintain that thiamine levels
are reduced but not enough to cause deficiency.)
• Irradiation can be used to prolong the shelf-life of certain
fruits and vegetables. Irradiated strawberries last weeks longer
than un-irradiated ones. (Why you would want weeks-old
strawberries is another question entirely.)
• The use of irradiation could eliminate the need for chemicals
to control pests for certain crops. (You have to admit, this
sounds good.)
Irradiation cons:
• Irradiation doesn’t make food perfectly safe. While it can
reduce microorganisms, it doesn’t entirely eliminate them. And
while it reduces bacteria levels, it’s not effective when it
comes to viruses or prions (which are responsible for Mad Cow
Disease, and, as far as I can tell, cannot be eliminated by
God).
• Irradiated foods cost more. The University of Wisconsin Food
Irradiation Group asserts that irradiated meat and poultry runs
3 to 5 cents more per pound. In these uncertain economic times,
that premium may be enough to further put off consumers who are
already a bit spooked by radiation because of that unfortunate
accident at Three Mile Island or that Cold War song by Sting.
But there
may be other reasons.
• Irradiation opponents see it as a Band-Aid solution to huge
problems in our food system that need to be fixed, not covered
over. They assert that the best way to prevent food-borne
illnesses and deaths is to clean up the dirty, unsafe, and
inhumane conditions at factory farms and slaughterhouses that
are ultimately responsible for large-scale contaminations. Check
out this clip of
Lou Dobbs
calling for FDA heads on a platter.
• Opponents of irradiation say that a diet high in irradiated
foods may not be safe in the long run because it damages the
quality of food. They further assert that the FDA’s approval for
irradiation was based on flawed and inadequate studies. For more
information, check out the
Organic
Consumer Association’s Stop Food Irradiation Project.
• Irradiation uses a lot of energy and could create enormous
environmental hazards. Here’s a cheery list of scary incidents
at irradiation facilities provided by
Public Citizen [PDF]. (Chant the Nuclear Industry Mantra:
“There was no danger to the public at any time. There was no
danger …”)
• Irradiation may not be suitable for all foods. Allegedly, it
makes tomatoes mushy. So, that nuked burger you just ordered
might be safer, but the Salmonella-infected tomato slice on it
could still get you.
Would I feed my own children irradiated hamburgers, albeit
well-cooked ones?
Although I’d like to say a resounding no, and that I only feed
my family local and organic foods all the time, I can’t pull
that off. (Did you hear that? It’s my Superwoman tiara clanging
to the floor. Damn! It just rolled under the fridge …) It is
highly likely that my family is already eating irradiated foods
whether I like it or not. While you’d think that a
large radura logo
would be required for each and every irradiated food, consumers
now have to squint to find he words “treated with irradiation”
or “treated by irradiation” on the ingredient list on labels.
Foods that are not entirely irradiated but contain irradiated
ingredients (such as spices) do not have to disclose them.
Restaurants and school lunch programs do not have to disclose
that they are using irradiated foods. Although I don’t think
that protecting our little ones from E.coli-infected CAFO
burgers is a bad thing, for the love of God, we need to be
informed. The FDA once proposed
relaxing labeling regulations to permit the term
“pasteurization” when it comes to certain irradiated foods. I’m
no scientist (a phrase that certainly would make my high school
chemistry teacher bust a gut laughing), but since when does
pasteurization involve Cobalt 60?
So, Carla, if you have any appetite left at all, go have a
well-cooked egg. Once your blood sugar (and pressure) return to
normal, do some soul searching and perhaps
make some calls.
With fond memories of Caesar salads,
Lou
PS: You mentioned milk: It hasn’t been approved for irradiation.
Pasteurization (the old-fashioned kind that involves heat), in
my opinion, is still the way to go. If you want the scoop on raw
milk, check out

by my esteemed colleague, Umbra Fisk.
