In addition to the safety concerns posed by Salmonella and other bacteria, keeping eggs at room temperature can have negative effects on their protein content. "Eggs stored at room temperature dry out and lose protein quality, even when they remain microbiologically safe to eat.
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.
Where should I keep my eggs? 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.
The case for refrigeration, however, is bolstered by the fact that the shelf life of refrigerated eggs is around 45 days, whereas unrefrigerated eggs are good for only about 21 days. This means that our squeaky clean and refreshingly cool American eggs do last longer than their cosmopolitan counterparts.
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.
Food Standards Australia New Zealand's Response
The statement continues to say that refrigerating whole eggs is not required because: The Salmonella bacteria which can contaminate an egg while it's inside the bird isn't present in Australian eggs.
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.
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.
You can leave eggs on the counter about two hours at room temperature or one hour if the temperature is 90 degrees 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.
Crack the egg into a bowl and examine it for an off-odor or unusual appearance before deciding to use or discard it. A spoiled egg will have an unpleasant odor when you break open the shell, either when raw or cooked." If the egg sinks and stands up, then it's not very fresh but still safe to eat.
Cleaning the eggs removes the cuticle, so the eggs must be kept at refrigeration temperature. Otherwise, the bacteria could easily enter the egg and multiply to dangerous levels. By keeping it out of the danger zone, salmonella can't multiply rapidly. Most other countries do not wash their eggs.
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.
It depends on how warm your kitchen is. If it gets hot in the summer or is well heated during the winter you should keep the eggs in the fridge. If it's a constant 18-21C they are best kept in the cupboard.
And are they safe to eat? We Americans, along with the Japanese, Australians and Scandinavians, tend to be squeamish about our chicken eggs, so we bathe them and then have to refrigerate them.
Though a few other countries around the world (namely Canada, Japan, and the Netherlands) do follow the American approach to egg safety, many skip the commercial cleaning and refrigeration process completely.
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.
The main thing with eggs, is that you want them to remain at a constant temperature, otherwise they can become unsafe for consumption. Fluctuations in temperature can cause salmonella in eggs, so the best place to store eggs is the fridge.
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.
Ripe tomatoes should still be kept at on your counter, uncovered, if you are going to enjoy the tomato in the next day or two. But any longer than that – the recommendation is to refrigerate. A so-so tomato is much better than a rotten, moldy tomato. Refrigeration will slow down the decay.
Egg washing is not required in Australia, but sale of dirty eggs is prohibited under Food Standards Australia New Zealand (FSANZ) requirements. A good option for cleaning dirty eggs is an automated washing machine system designed to produce a high recovery rate of first grade eggs.
According to the FDA, eggs should be left at normal room temperature (68°F to 70°F) no more than two hours; or at higher temperatures no more than one hour.
Off-color egg white, green or iridescent – Spoilage due to Pseudomonas bacteria, a very common type of bacteria that healthy people often carry without knowing it. This bacteria produces a greenish, fluorescent, water-soluble pigment in the egg white.
The theory is that, as an egg ages, the air pocket inside it grows larger, buoying an old egg to the surface. But, according to Dr. Schaffner, “there is no scientific basis for the egg float test.” So experimenting to see if your egg sinks or swims is not a reliable way to measure its quality.
