Do Fresh Eggs Need to Be Refrigerated? Freshly laid eggs need to be refrigerated immediately. Fresh eggs purchased from a farmers market need to be refrigerated as soon as you get home. Per USDA guidelines, eggs should be stored at 40 degrees F or below to help minimize the risk of Salmonella.
Store whole eggs in a cool dry place, ideally in the fridge, until you use them. Storing eggs at a constant cool temperature will help to keep them safe. Do not use eggs after their 'best before' date.
Storing eggs at room temperature isn't advised in the United States because of Salmonella and other pathogens. When we asked Clark whether it's safe to keep store-bought eggs at room temperature in the U.S., her answer was a clear "no."
And salmonella can spread quickly when eggs are left out at room temperature and not refrigerated. “A cold egg left out at room temperature can sweat, facilitating the movement of bacteria into the egg and increasing the growth of bacteria,” the USDA states on its website.
Should you put eggs in the fridge? Eggs don't need to go in the fridge, but they'll last longer if they do. If they've been washed or refrigerated before (for instance, at the supermarket) then they should also go in your fridge at home.
In Europe it's a health risk to store eggs in the fridge. In Australia, it's a health risk to store them out of the fridge. Who is right? The answer is all about Salmonella, the general name for about 2,000 types of bacteria that lead to food poisoning.
If that's the case, then why are eggs not stored in fridges at the supermarket? Well, there's a simple explanation for that. It's apparently because store temperatures are kept below 20ºC, so refrigeration is unnecessary. 'This also prevents significant temperature fluctuations.
In Europe, farms vaccinate chickens against salmonella. That means the cuticle is still intact when eggs are sold. Refrigerating eggs with the cuticle intact could actually cause mildew to grow. Which could cause… you guessed it salmonella contamination.
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.
If you've been to a country other than the USA, you might have! Most countries do not store their eggs in refrigerators. Instead, they leave them out at room temperature. This might seem like a food safety hazard, but both methods are safe.
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.
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.
Refrigerator Storage: Refrigerate eggs at 40°F or less. Store them in their original carton on an inside shelf and away from pungent foods. The temperature on an inside shelf remains more constant than one on the door, which is opened and closed frequently.
The water test for egg freshness
First, fill a bowl or glass with about four inches of cold water and gently place your egg(s) inside. Very fresh eggs will sink to the bottom and lay on their sides. If an egg stays at the bottom but stands on its small end, it's still acceptable to eat; just not quite as fresh.
If the eggs sink to the bottom and lay flat on their side, they're still fresh. However, if they sink, but stand on one end at the bottom of the glass or bowl, they're not as fresh but still edible. Of course, if any eggs float to the top, they shouldn't be eaten.
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.
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.
Why are Italian eggs never refrigerated? Head to an Italian grocery store and you'll find eggs on grocery store shelves and never refrigerated. There's a reason for this. Eggs have a protective outer layer that protects them from disease and bacteria.
You need to take the same precautions that you would for chicken, meat, seafood and dairy products. Eggs must be kept clean, intact and fresh; stored at cool temperatures; and cooked well.
The delay in the growth of Salmonella in eggs has been found to be temperature dependent. For eggs held at room temperature, growth may be inhibited for 2 to 3 weeks. Conversely, for eggs stored at 37°C, growth may occur in a few days.
The best way to keep eggs is to store them in their original carton in the refrigerator as soon as possible after purchase. Cartons reduce water loss and protect flavours from other foods being absorbed into the eggs.
Eggs should not be stored on the refrigerator door, but in the main body of the refrigerator to ensure that they keep a consistent and cool temperature. Leftover raw egg whites and yolks should be put in airtight containers and stored in the refrigerator immediately.
If eggs are left unwashed with the bloom intact, you can place them on your kitchen counter. Unwashed, room temperature eggs should keep for about two weeks. If you aren't planning to eat your eggs for a while, we recommend refrigerating them.
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.
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.
