Eggs in the US are sold by the refrigerator, but not just in America. This happens in many other countries as well. People who have their chickens in the village leave the eggs out of the fridge until they are ready to cook them, but some also put them in the fridge. But what is the right way?
According to experts, anyone who has chickens at home can keep the eggs out of the fridge for a few days after you have confirmed the health of the chickens and the cleanliness of the cage. Even if the eggs are unwashed, they can stay that way for several days. This is because eggs have a natural layer that protects them from bacteria. If the eggs are washed, this layer is removed causing bacteria to penetrate faster inside the egg. If eggs are washed, the best advice to keep them fresh is the refrigerator.
As for store-bought eggs, the advice is the fridge. American egg makers wash the eggs to make sure they are clean, because there is a risk of salmonella in them as well. So the protective coating is removed before the eggs arrive at grocery stores, so once you buy them, put them in the fridge. Business Insider reported some time ago that many markets required manufacturers of unwashed eggs to protect them as long as possible from the risk of salmonella.
Of course, to be safe, you can always choose to keep eggs in the fridge. If an egg stays at room temperature for at least a day, it is approximately equivalent to seven days in the refrigerator, so you should eat them faster.
