No, because washing may aid the transfer of harmful bacteria like Salmonella from the outside to the inside of the egg. The priority in egg production is to produce clean eggs at the point of collection, rather than trying to clean them afterwards.
No. It's not necessary or recommended for consumers to wash commercially packaged eggs, and it may actually increase the risk of contamination because the wash water can be "sucked" into the egg through the pores in the shell. When the chicken lays the egg, a protective coating is put on the outside by the hen.
The short answer is “No”. Eggs are laid with a natural coating on the shell called the “bloom” or “cuticle”. This coating is the first line of defense in keeping air and bacteria out of the egg. Eggshells are porous, so when you wash them you're removing that natural barrier.
“Because the shell is so porous, you're pushing it back through the surface of the egg,” she says. And that poses a far bigger risk of contaminating the part of the egg that you're actually going to eat.
Egg washing is not required in Australia, but sale of dirty eggs is prohibited by Food Standards Australia New Zealand (FSANZ). Storing washed eggs below 7°C can help reduce the ability of Salmonella to grow.
Eggs that are not thoroughly cleaned can cause human illness. Salmonella, a disease associated with poultry, can also be passed through contaminated shells. Dirty shells contaminate clean cooking areas, kitchen utensils, food, or hands. Eggs have small pores which harmful bacteria can enter.
Commercial eggs are required to be pre-washed, and honestly, considering the living circumstances of many of the birds, it's better that way. However, farm fresh eggs are a different story. You don't actually NEED to wash your eggs, although there are some circumstances where you may want to.
To clean your eggs without water use, use a sponge or towel to rub off all dirt and droppings from the egg gently. Never use the same cloth or sponge on other eggs. Always discard it after use.
Fresh eggs, even those with clean, uncracked shells, may contain bacteria called Salmonella that can cause foodborne illness, often called “food poisoning.” FDA has put regulations in place to help prevent contamination of eggs on the farm and during shipping and storage, but consumers also play a key role in ...
In the U.S., vaccination is not required, but eggs must be washed and refrigerated from farm to store, and producers must follow a host of other safety measures.
The best method for how to wash fresh eggs is by using warm water that is at least 90 degrees Fahrenheit. Washing with warm water causes the egg's contents to expand and push dirt and contaminants away from the shell's pores. Never soak eggs, even in warm water.
How to store fresh eggs. Once they're out of the coop and free of any of the feathers and poop that came with them, eggs should be refrigerated. Although unwashed eggs with cuticles intact can safely be stored at room temperature, refrigerating your eggs will help them last longer; about 5-6 weeks.
But — and here is the big piece of the puzzle — washing the eggs also cleans off a thin, protective cuticle devised by nature to protect bacteria from getting inside the egg in the first place. (The cuticle also helps keep moisture in the egg.)
When and How to Use an Egg Wash. If you're making bread or dessert, you should apply the egg wash right before you bake your creation, though some recipes may tell you to brush on the egg wash halfway through the baking process. The longer the egg wash stays in the oven, the darker it becomes.
The eggs stored in cold temperature tend to undergo condensation when they are taken out to room temperature. This promotes the growth of bacteria over the egg shell, thereby contaminating the egg and making it harmful for human consumption.
WASHING EGGS • Wash and rinse eggs in warm to hot water. Water temperature in the 90-120oF range is best; hot tap water is generally 120oF. The temperature should be at least 20 degrees warmer than the egg. If “freshly laid” eggs are gathered, use temperatures at the warmer end of the range.
You don't need to refrigerate farm fresh eggs. Eggs are laid with a near invisible coating called the "bloom" or "cuticle" on the shell. What is this? This coating helps keep air and bacteria out of the egg, keeping the egg fresher longer.
Most other countries do not wash their eggs. They put a higher priority on the cuticle, since it naturally keeps the egg safe from salmonella. By not removing the cuticle, it also eliminates the need to refrigerate the eggs after they have been laid.
Husbandry and hygiene practices in Europe
In Europe, it is unlawful to wash eggs because this process is believed to damage an outside layer of the egg shell known as the cuticle, making it easier for bacteria to penetrate the inside of an egg.
By leaving your eggs unwashed, the natural barrier remains intact. Commercial egg producers are regulated and required to wash all eggs before shipment, which is why the eggs you buy in the supermarket are so tidy.
In the UK, Grade A hen eggs may not be washed because the process is thought to "aid the transfer of harmful bacteria like salmonella from the outside to the inside of the egg," according to the Food Safety Authority of Ireland.
Never immerse or soak the eggs in water. Wash the eggs under running water from the faucet or spray the eggs in washer flats or wire baskets with warm water. Let them sit and wipe dry with a dry paper towel one at a time. Place the clean eggs in another basket or flat.
Don't wash the eggs until you use them, unless they're soiled. Fresh unwashed eggs do not need to be refrigerated for several weeks. Always refrigerate washed eggs. Eggs will maintain a higher quality when stored in the refrigerator – washed or not.
Freshly laid eggs can be left out at room temperature for at least a month before your need to start thinking about moving them into the fridge. We like to make sure we eat ours in under two weeks (because they tend to taste better), but so long as the egg is eaten within one month of it being laid, you will be fine.
The case for refrigeration, however, is bolstered by the fact that the shelf life of refrigerated eggs is around 45 days, whereas unrefrigerated eggs are good for only about 21 days.
