Why are eggs not allowed on the shelves in the U.S. that haven t been washed?

They think that eggs that are not washed will carry a lot of bacteria. It can contaminate other foods. So it's not allowed to be put on the shelf.

Because the concept is different, the United States is to eliminate the bacteria that contaminate the eggs, so as to eat safe eggs.

Because eggs are not washed, there will be a lot of bacteria left on the top, which can easily spread to shoppers' hands.

Because unwashed eggs are very dirty and have a lot of bacteria, they need to be cleaned before they can be eaten.

Because they think that eggs that are not washed carry a lot of bacteria. It can contaminate other foods.

This may be because they feel that unwashed eggs are unhygienic and are not allowed to be placed on the shelves.

Because the eggs are picked up from the chicken coop, they may have a lot of germs on them, and they can be reduced by washing them.

Americans spray an oil layer on the eggs to keep bacteria out, and then put them in the refrigerator to prevent microorganisms from multiplying.

This may be because there are many bacteria on the outside of the eggs, so they should be washed first.

The original answer was: eggs cannot be washed in the UK. In the United States, eggs must be washed. Why are there different regulations? I guess the bacteria don't know which country they're in.

UK law makes it illegal for egg producers to wash eggs or to wash eggs in any way.

Why? This is done to ensure that egg producers have a clear interest in ensuring that their hens are kept in the best possible conditions. They can't let the chickens roll in the dirt, they can't let the chicken poop get on the eggs, and they can't get rid of it.

The egg has a film on the outside to protect what's inside. That layer of film has been destroyed by cleaning, and removing it is more likely to lead to contamination.

If you need to wash your eggs, then your chickens are not being kept in a clean and tidy environment. If you don't take care of your chickens, how can you trust keeping your egg wash water clean?

Go to a supermarket in the UK and you won't find eggs in the fridge or freezer – they're on the regular shelves at store temperature**.

There's a reason for this – it prevents moisture from getting on the surface of the egg and destroying the protective layer of the egg – just like condensation can occur when you put an egg out of a cold fridge and into a warm car.

About 90% of eggs in the UK come from salmonella vaccination.

Vaccine for chickens. It doesn't matter what you do after the eggs have laid – if the chicken contains salmonella, then there's a good chance that the eggs do. These eggs from "safe" chickens are printed with a red lion motif.

Pulled an egg out of my fridge that was labelled as made in the UK with the lion logo, producer and packaging details, preferably before the date.

10% without the lion mark is sold directly from the farm.

This is probably the reason why all human Salmonella cases from eggs in the UK are less than 600 per year. population in the United States.

to about 3,000 cases of Salmonella from eggs will occur in the United States if eggs are treated in the same way as in the United Kingdom. But this is not the case, and there are about 142,000 cases of salmonella infection from eggs in the United States each year.

In Europe and the UK, the opposite is true. EU regulations prohibit the washing of eggs. The idea is that preserving the protective film is more important than washing off the dirt.

At most U.S. farm stalls and farmers' markets, eggs are sold unrefrigerated. Many chefs store unwashed eggs bought from small producers in cabinets and wash them before using them – not at all if they are boiled in boiling water. However, if you buy refrigerated farm eggs, it's best to keep them refrigerated.

Leaving them at room temperature if they are not ready to cook immediately may cause water vapor to condense, which can destroy that protective layer or create mold. No matter where you buy it, it's okay to keep refrigerated eggs for four or five weeks. Eggs that are not refrigerated are best eaten within a week, although two weeks may be fine.

1) The culture of the country is different, (2) the living habits of individuals are also different, and (3) the culture of the local ethnic group is different, resulting in various regulations.

Because different regions have different living habits and customs. In particular, the habits of the two countries are very different.
