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.
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.
In Australia, most egg producers recommend storing eggs below 15C. This makes the fridge the best place for them. The Australian Eggs organisation also recommends a “climate-controlled refrigerated environment” for storing eggs.
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."
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. Make sure you rotate stock and use the oldest eggs first.
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.
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. This will help them last longer.
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.
Many European countries, like the UK, vaccinate their hens to prevent the transmission of salmonella when the hens lay eggs. The vaccinations, in conjunction with the protection of the “cuticle,” are thought to protect the European eggs from bacteria, therefore they don't refrigerate their eggs.
The practice of storing eggs in lime water goes back centuries, and it's still one of the best ways to preserve eggs without refrigeration. Anyone who has kept chickens knows that egg production doesn't always line up with demand.
A cold egg left out at room temperature can sweat, facilitating the growth of bacteria that could contaminate the egg. Refrigerated eggs should not be left out for more than two hours.
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.
Without the cuticle, eggs must be refrigerated to combat bacterial infection from inside. In Europe, it's illegal to wash eggs and instead, farms vaccinate chickens against salmonella. With the cuticle intact, refrigeration could cause mildew growth and contamination.
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.
COVID increased demand relative to supply and also significantly increased operating costs. There is now a push from major retailers to transition from caged eggs to cage-free eggs which is having a significant impact on caged eggs - which traditionally make up the bulk of egg supply in Australia.
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.
Though eggs are sold un-refrigerated in New Zealand, egg organisations (such as I Love Eggs) recommend refrigerating eggs at less than four degrees to give them longer life – around 35 days after being laid. But it must be said: eggs don't have to be refrigerated in New Zealand.
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.
Refrigerating eggs, or storing them in a cool location is one of the most common ways to extend the shelf-life of fresh eggs. Fresh eggs that are stored in a carton and kept on the coolest shelf in the fridge will last up to 5 weeks. They can last longer if the humidity is high to prevent too much evaporation.
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.
Yes, unwashed freshly-laid eggs from backyard chickens or a local farm can safely be stored at room temperature for several days or even a couple of weeks.
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.
Eggs have small pores which harmful bacteria can enter. Even shells that appear clean can carry germs. Even so, eggs do not need to be washed. If not washed, they can keep without spoiling for weeks without refrigeration.
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.
The Egg Safety Center has many readers who often ask a similar question: why is it safe to eat room temperature eggs in some parts of the world, but not in the USA? The answer has to do with bacteria: Salmonella. In the United States, it's more than a food safety recommendation that eggs be refrigerated – it's the law.
