Egg Safety: Cholesterol and Pasteurization
My journey into egg safety and ultimately pasteurized eggs started, of course, with a cupcake. It was time to make my “Better Than Sex Chocolate Cupcakes“, and as part of the cupcakes I wanted a chocolate mousse filling. It had to be a real chocolate mousse made with raw eggs.
My chocolate mousse recipe called for 8 eggs. High cholesterol, here we come! Or not! - In the early 1970’s, the American Heart Association declared the egg a threat to health. This was because it contained 278 milligrams of cholesterol and food scientists had just announced that people shouldn’t have more than 300 milligrams of cholesterol a day.
- The 300 milligram per day standard was set because scientists were concerned about the connection between high cholesterol and heart disease and thought they could help people by setting a safe limit. They arbitrarily decided the safe limit should be half of what the average person ate (580 milligrams) so they decided on 300.
- It was later determined that cholesterol in humans is mostly created by the way we process food, not by eating foods that contain cholesterol (like eggs).
- Over the next 25 years, no study was done that linked dietary cholesterol and heart disease.
- In 1999, the Harvard School of Public Health conducted a study funded by the National Institute of Health that showed no heart health hazard connected to egg eating. This prompted the American Heart Association to say that four eggs a week would be fine.
- The American Heart Association later upped that number to an egg a day.
Read the chapter. I couldn’t do it justice without completely plagiarizing. FYI: Wikipedia has some of the same information in case you were wondering if this was just one person’s crazy egg propaganda.
Will Raw Eggs Give You Salmonella?
Gina points out that salmonella was the next attack on eggs after cholesterol. If you watch the video on the safeeggs website, you would think that we were all going to die from salmonella. Last Chance to Eat paints a very different picture.
Salmonella produces a mild form of typhoid fever in humans. Most people don’t notice it, but it can be fatal in susceptible people. My dad actually had salmonella years ago (I’m not sure if it was from eggs) and he was extremely sick. He got better quickly and all was well. However, it is definitely something I want to avoid.
According to Last Chance to Eat, salmonella in eggs is correlated with bad living conditions for the hens. Basically, salmonella can be contracted in an egg if it gets chicken poo on it when things aren’t clean. In response to public concerns, the egg industry worked on improving the unsanitary conditions. Last Chance to Eat says that your chances of getting salmonella from an egg are now only 1 in 20,000. Wikipedia says it’s 1 in 30,000. Note that these numbers vary outside of the US.
Pasteurized Eggs
One way to make sure that you don’t get sick from eggs is to use pasteurized eggs. These eggs are not available everywhere, however they are available in St. Louis at Dierbergs from safeeggs. They are the ones marked with the P in the photo to the left. Last Chance to Eat describes the process: “A computerized conveyor belt passes the eggs through successive baths of water, heated from 144 degrees to 162 degrees in order to destroy any pathogens.”
Gina goes on to say that pasteurization destroys the taste of the egg. Others agree. The San Fransisco Chronicle has a detailed article where the author does a series of tests to compare pasteurized vs. non-pasteurized eggs in a variety of ways. The pasteurized egg lost every test.
I decided to try my own test.
Pasteurized vs Non-Pasteurized Scrambled Eggs in a Blind Taste Test
First, I cracked both eggs. This part was not done blinded. They appeared very similar, but the pasteurized egg had cloudier egg whites. Look closely at the photo on the left. The back egg has not been pasteurized.
Then, my husband scrambled them both up. I bake, he scrambles.
I closed my eyes and he randomly fed me some of each cooked egg. I was hard-pressed to pick which one I liked better. However, I chose the non-pasteurized egg, as did all the other tasters. Groom 2.0 said he couldn’t tell the difference. The difference was very minimal, but the non-tampered-with egg had a richer flavor.
Which Type of Egg Did I Use in the Mousse?
I had to go with the pasteurized egg in my chocolate mousse. Even knowing how slim the chances are of getting salmonella, I didn’t want to risk it. What if Bride and Groom 2.0 pick the cupcake with the mousse for the wedding? I wouldn’t want their wedding to be ruined by a honeymoon salmonella disaster.
Call me chicken.
