Most people will still put them in the fridge at home, but because in Germany and most of Europe eggs are not washed and sterilized, unlike in the US and Canada, whereby the protective layer on the outside can be damaged, eggs don't HAVE to be refrigerated so the store sells them on the shelf.
In most European countries, Salmonella is kept under control with preventative measures like vaccination. Farms are usually not allowed to wash eggs, so the cuticles remain intact, precluding refrigeration.
Eggs there are not required to go through extensive washing, which leaves the protective coating on the egg. Because this coating remains on the eggs, authorities feel it is safe for them to be sold at room temperature. In some European countries, vaccines are used to prevent Salmonella in laying hens.
However, farm-fresh eggs and those in European countries and most of the rest of the world, can be safely kept at room temperature for up to two weeks, says Chau.
Most egg producers in Australia recommend that eggs are stored below 15°C. This means that if the temperature in your kitchen is warmer than this, and in Queensland it most likely will be, then you should store your eggs in the fridge.
British authorities actually discourage refrigerating eggs on the theory that chilling and then warming could create condensation, which would allow salmonella to penetrate the shell.
Food Standards Australia New Zealand's Response
The statement continues to say that refrigerating whole eggs is not required because: The Salmonella bacteria which can contaminate an egg while it's inside the bird isn't present in Australian eggs.
Avoiding temperature fluctuation is critical to egg safety. A cold egg left out at room temperature can sweat, facilitating the growth of bacteria that could contaminate the egg.
Upon researching, it seems refrigerating eggs is an American initiative because of a salmonella fear in US eggs. In Europe, Australia, and New Zealand, there is very little chance of salmonella being present in eggs (in fact, European chickens are vaccinated against it).
Why The U.S. Chills Its Eggs And Most Of The World Doesn't : The Salt In many countries, eggs aren't refrigerated and they're still considered safe to eat. But in the U.S., we have to chill them, because we've washed away the cuticle that protects them from bacteria.
In the US, eggs that aren't refrigerated could cause salmonella poisoning—meanwhile, Europe considers it a health risk if eggs are refrigerated. This cultural difference stems from the way eggs are processed before they reach stores.
A general rule, unwashed eggs will last around two weeks unrefrigerated and about three months or more in your refrigerator. If you're experiencing an egg boom, it's smart to refrigerate any unwashed fresh eggs you aren't planning to eat immediately.
The rule of thumb? You can leave eggs on the counter about two hours at room temperature or one hour if the temperature is 90 degrees or hotter before you start to worry, per the Egg Safety Center. After two hours, you'd be safer to throw those eggs out and get a fresh dozen rather than chance it.
Culture of Eating Raw Eggs
Compared to other countries, eggs in Japan are considered to be much less contaminated by salmonella, one of the causes of food poisoning, and therefore raw eggs can be eaten without worry. The most popular way to eat raw eggs is “Tamagokakegohan” (TKG).
It's not a natural trait of a fancy European breed of hen or a sign of overly pampered birds. The yolk color actually comes from what the hens eat: a diet rich in carotenoids, the natural yellow-orange pigment found in fruits (cantaloupe), vegetables (carrots, sweet potatoes, and kale), and flowers.
According to eggs.org.au (best domain name ever), the cartons we see on the shelves of Australian supermarkets contain eggs that were laid up to 42 days ago. That's six weeks. All we have to go by, traditionally, is the 'use-by' date. Or the even more confusing 'best before'.
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 Aren't Refrigerated in all Parts of the World
However, here in the United States, commercial egg farms are required to clean the eggs before packaging them up in cartons to be shipped to supermarkets, so that means they require refrigeration.
They are not stored in the fridge in shops because they would amass condensation on your way home and this is what will encourage contamination through the shell.
Storing. Eggs are absolutely fine stored in a cupboard provided you will be using them before the 'best before' date, but they will last longer in the fridge. Keep them in their original box rather than in special egg racks in the door.
The lower and consistent temperature limits moisture lost through the pores of the egg shell. This keeps the egg fresh right up to the "best before date" that's stamped on the exterior of the carton.
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.
If refrigerated, eggs typically stay safe well after their expiration date. Regardless of what that date actually is, the optimal storage time for raw eggs in their shells, according to the USDA, is three to five weeks.
Cleaning the eggs removes the cuticle, so the eggs must be kept at refrigeration temperature. Otherwise, the bacteria could easily enter the egg and multiply to dangerous levels. By keeping it out of the danger zone, salmonella can't multiply rapidly.
He says the best way to preserve raw eggs is to store them in a solution of slaked lime (you can find it at a building supply store) and water, which, in his test, had a 100 percent success rate after eight months. That same Genesee Farmer article claimed this method could preserve eggs for six years or longer.
