To know: do you make this mistake with your eggs?

The ordeal lasts about a week. But some people will not cure themselves. Hospitalization is essential. Because the bacteria, after proliferating in the intestine, join the bloodstream, causing widespread infection and death of the patient.

And the risk is very big!

Do you make this mistake with your eggs? According to the World Health Organization (WHO):

“Salmonellosis is one of the most common and widespread foodborne illnesses. It is estimated that there are several tens of millions of human cases each year worldwide, and the disease causes more than one hundred thousand deaths a year. [2]

Humans usually contract salmonellosis by consuming contaminated products of animal origin, particularly eggs.

The egg must be contaminated by a large number of bacteria, which is more common in old eggs, laid for several days or weeks.

On the other hand, the hotter it is, the faster the bacteria breed. Scientific research has confirmed that an egg infected with Salmonella that is stored at room temperature for more than 3 weeks will contain many more bacteria than if kept in the refrigerator [3].

So, score 1 – 0 for Americans who keep their eggs in the fridge?

Nature is well made

Not so fast.

Because nature is well done. Normally, your egg should not contain bacteria.

Indeed, just before laying it, the hen wraps the egg with a protective liquid that prevents the bacteria from passing.

This liquid dries and forms a layer called a cuticle. The cuticle protects the egg from the penetration of bacteria through the shell. Even if the egg then rolls on excrement contaminated with salmonella, which is the most frequent mode of contamination, salmonella will remain outside.

Why do not you wash the eggs

But this effective tactic of protection falls on the water, it is the case to say, if you wash your eggs instead of keeping them as they are after picking them up.

The washing of the eggs removes all or almost all the egg cuticle, thus depriving it of a natural barrier against microbes.

However, in the United States, commercially distributed eggs are still washed [4]. They lost their cuticle. This is why they are very vulnerable to contamination and should be kept refrigerated.

In Europe, washing is forbidden for this reason.

According to the legislation (EC) N ° 589/2008 of 23 June 2008 on eggs, quoted above:

“In general, eggs should not be washed or cleaned because such practices can damage the shell, which is an effective barrier against the entry of bacteria, with a line of antibacterial properties. (…) In addition, eggs class A should not be washed because of potential damage to physical barriers, such as the cuticle, that may occur during or after washing. [5]

Certainly, you will tell me, this explains why we should not wash the eggs.

But why not avoid washing them and keeping them in the fridge, since this slows bacterial growth?

Would not we have the best of both worlds?

Excellent question, which I will answer now.

Why do not refrigerate eggs

The problem is that when you take an egg out of a fridge, it gets covered with condensation.

According to the European regulations above, this humidity:

“Facilitates the growth of bacteria on the shell and probably their penetration into the egg. Therefore, eggs should be stored and transported at room temperature, and should generally not be refrigerated before being sold to the final consumer. “

Even if the eggs are not washed, condensation is a problem. The Europeans have deduced, logically in my opinion, that it is better not to wash the eggs, and not to refrigerate them.

The United States has made the opposite choice: they prefer to clean the eggs better at first, even to damage the cuticle, and then keep them always cool.

This poses in my opinion a problem.

Like us, Americans go to the supermarket, put the eggs in their shopping cart and then in the trunk of their car. But because their eggs are refrigerated in the store, they get covered with condensation and are wet when they are put back in the fridge. Deprived of the cuticle due to washing, they are then more likely to be contaminated by bacteria.

In addition, according to Mark Williams, expert in egg production:

“In Europe, the fact that it is not possible to wash the eggs before selling them encourages the good behavior of the farms. The chicken farmer understands that it is in his interest to produce eggs as clean as possible without washing, because no one will want to buy his eggs if they are dirty. [6] »

Does this mean that American eggs, because they are washed, are more likely to be produced in warehouses full of chicken feces, and at high risk of salmonella contamination?
