Food safety types – practice what you preach

My first column from the Texas A&M Center for Food Safety:

I dream about thermometers.

In the latest combination of fact and fiction, accuracy and amalgamation, I was at a roadhouse-style restaurant and settling the bill with an powell's.food.safety.worldassistant manger who had seen it all and stopped having fun years ago, when smoke started billowing from the open grill.

A waitress tried to serve the burger — black on the outside, raw on the inside – when my food safety nerd friend went to intervene.

I joined the fray, and insisted a thermometer was necessary to determine if the burger was safe.

The assistant manager said, “I heard you were the biggest loser in town.”

Then the dream ends.

In 1998, the U.S. Department of Agriculture very publicly began to urge consumers to use an accurate food thermometer when cooking ground beef patties because research demonstrated that the color of meat is not a reliable indicator of safety.

USDA Under Secretary for Food Safety at the time, Catherine Woteki, said, “Consumers need to know that the only way to be sure a ground beef patty is cooked to a high enough temperature to destroy any harmful bacteria that may be present is to use a thermometer.”

At the time, I said, no one uses a meat thermometer to check the doneness of hamburgers. The idea of picking up a hamburger patty with tongs and inserting the thermometer in sideways was too much effort (others insist the best way to use a tip sensitive digital thermometer is to insert into the middle of the patty at a 45 degree angle).

I was wrong.

Shortly thereafter, I started doing it and discovered, not only was using a meat thermometer fairly easy, it made me a better cook. No more extra amy.thermometerwell-done burgers to ensure the bugs that would make me sick were gone. They tasted better.

By May 2000, USDA launched a national consumer campaign to promote the use of food thermometers in the home. The campaign featured an infantile mascot called Thermy that proclaimed, “It’s Safe to Bite When the Temperature is Right.”

Fourteen years later, the converts are minimal. Canada came to the thermometer table a few years ago, but the laws of physics are apparently different north of the 49th parallel, with a safe temperature for poultry being 180F in Canada, but 165F in the U.S.

The Aussies are slowly warming to the idea of thermometers but the UK is still firmly committed to piping hot (cue Dick van Dyke in Mary Poppins).

Science-based depends on whose science is being quoted to whose ends. The fancy folks call it value judgments in risk assessments; Kevin Spacey in the TV series House of Cards would call it personal advancement.

Food safety is losing to food porn with thermometers.

Many celebrity chefs actively denigrate the use of a thermometer when cooking. Some claim to know meat is safe using the finger method, which is akin to a shaman curing a sick child, or dowsing to find water (chance figures heavily –even a blind squirrel finds a nut once in a while).

Gordon Ramsey says, “A thermometer? The day we need that to cook a breast of chicken — you, get out.”

Seamus Mullen, the chef and an owner of the Boqueria restaurants in the Flatiron district and SoHo in New York City uses a wire cake tester, or any thin, straight piece of metal.
“We stick it in the middle through the side. If it’s barely warm to the lips, it’s rare. If it’s like bath water, it’s medium rare. The temperature will never lie. It takes the guesswork out of everything.”

Why not stick in a thermometer — a thin piece of metal?

I can no longer cook without a meat thermometer; I feel naked, like in a dream.

Yet almost everyone else in the U.S. can, where only 7 per cent of the population report using a thermometer on a regular basis — and some of those are surely lying.

We’ve known the basics for increasing thermometer use for over a decade: people care more about being better cooks than serving safe food, and lead by example.

Tip-sensitive digital thermometers need to be widely available, and food safety types need to use them properly. Not just at home, but at school events with the kids, at potlucks, at any gathering that involves food.

Stop dreaming, start doing.

Dr. Douglas Powell is a former professor of food safety who shops, cooks and ferments from his home in Brisbane, Australia.

  • Using a meat thermometer to check cooking temp or internal temp of meat is the only way to tell if the meat is safe, as supported by researchs & public health articles. It is strange to hear that the chef in NYC inserting a thin wire to test the temp on his lips!!! Gross, this won’t work plus what a way to cross-contaminate food.. or to burn his lips?

    As a food safety type, I’m ashamed to admit I don’t own a thermometer. But then again, I don’t really cook because I’m terrible at it. However, I did visit several grocery stores recently to purchase one… and if you can imagine, I could not find a tip-sensitive digital thermometer. Perhaps more people would use them if they were actually available.

    Although I must admit that the converts to thermometers has been slow, I have seen improvements. As for the wire thing, I was taught a similiar method early in my cooking career along with a few other silly things. However today, because of education combined with accepting the science, I know these processes are not acceptable or efficient and place my business, customers and reputation in harms way. When I teach food safety classes now, I like to tell them that when I started in the food business you could actually purchase th elong wooden boards, used on the service lines, with ashtrays built into them. No one would dare do this today but it was done. Culinary arts are no different than any other industry. It must evolve using the science and knowledge of the day. Think of where we would be today if the science of medicine, astronomy, physics, chemistry were ignored the way we ignore the science of food. As for your comment “the dream ends” Dr. Powell, remember that many of the first scientists were crucified as heretics. But we know better today don’t we?

    I think I would be lost at home without my thermometer. I had one of the supermarket cheapies for awhile which suck for quick measurements. My new one even came with certificate of calibration and 4 second response time and really we can spend hundreds on a coffee maker so why complain about $100 to have a great tool to serve safe food which is still tender and flavoursome.
