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 F 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.
How Long Can Eggs Sit Out? According to the USDA, refrigerated eggs should not be left out for more than two hours.
But what is the ideal expiry date for eggs? “The shelf life of an unrefrigerated egg is 7 to 10 days and for refrigerated egg it's about 30 to 45 days,” notes Dr Batra.
You're in the U.S. so your eggs should have been refrigerated and have now gone without that cold-temperature protection for at least 12 hours. The United States Department of Agriculture advises against eating eggs that have been outside of refrigeration for more than two hours.
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.
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.
This is a requirement of the Food Standards Code. Refrigeration of eggs throughout the supply chain, including during wholesale and retail storage could reduce the risk of human Salmonellosis.
While egg farmers supply a safe, clean, fresh product, it is possible for eggs to become contaminated by the food poisoning bacteria Salmonella. The good news is Salmonella is killed instantly at 74oC. So even if you are unlucky enough to get an egg with bacteria on it, the food will become safe by cooking it properly.
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."
Can You Put Room Temperature Eggs Back In The Fridge? If the eggs have been at room temperature (68-70 degrees), for less than 2 hours, you can put them back in the refrigerator. If they've been at a higher temperature than 70 degrees, you can put them back if they've been out less than 1 hour.
Simply fill a bowl with cold tap water and place your eggs in it. If they sink to the bottom and lay flat on one side, they are fresh and good to eat. A bad egg will float because of the large air cell that forms at its base. Any floating eggs should be thrown out.
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.
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.
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. The U.S. Department of Agriculture (USDA) determined that the best way to fight Salmonella contamination is by sanitizing the eggs before they reach the consumer.
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.
The Centers for Disease Control estimates that 1 in every 20,000 eggs are contaminated with Salmonella. Persons infected with Salmonella may experience diarrhea, fever, abdominal cramps, headache, nausea and vomiting.
Dirty eggs may have harmful Salmonella bacteria on the shell. Cracked eggs allow Salmonella to enter and grow inside the egg. However even eggs with clean, uncracked shells can pose a risk if handled incorrectly.
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.
You can eat eggs past their expiration date. Just be sure to keep your eggs egg-cellent by storing them correctly. If you don't know if an egg is good or not, you can try the float test or give it a whiff. If it doesn't pass the test, throw it away.
