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.
Eggs must be kept clean, intact and fresh; stored at cool temperatures; and cooked well. Follow these practical tips to ensure that the eggs you sell stay safe: Do store eggs in their outer boxes at below 20 °C, until displayed for sale.
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.
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.
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 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.
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."
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.
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.
Americans, along with the Japanese, Australians and Scandinavians, all wash their eggs and therefore have to refrigerate them. After the chickens lay the eggs, they're immediately placed into a machine that washes them with soap and hot water.
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.
Commercially sold eggs in America go through a washing and sanitizing process that clears contaminants, but also removes the natural protections that eggs have against bacteria. Because of this, eggs are refrigerated during processing and must remain chilled in order to reduce the risk of salmonella contamination.
What's the best way to store eggs? 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.
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.
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.
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, eggs are kept at a constant “room temperature” from production to the supermarket shelf, to avoid any thermal shock. This is to prevent any condensation from forming, which would allow bacteria to pass between the outer shell and the inside of the egg.
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.
There are a few other countries that also sterilize and refrigerate eggs before they're sold. If you live in Australia, Japan, Denmark and Sweden, your eggs are just like those in North America – so make sure you're keeping them refrigerated.
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 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.
Although egg washing is not a requirement in Australia, sale of dirty eggs is prohibited by Food Standards Australia New Zealand (FSANZ). Any washing and sanitising process needs to reduce bacterial load on the eggshell, as visibly clean eggs can still be highly contaminated with Salmonella.
The egg industry faces supply issues impacted by rising feed costs and a hangover from the pandemic restrictions which reduced laying flocks. Egg Farmers of Australia told SBS in 2022 the industry had been impacted by bushfires, floods, droughts, the mice plague, COVID-19 and increased production costs.
What is this? 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.
