Food safety experts explain that eggs can remain safe to eat for quite some time after the date on the carton, especially if they are stored properly in a refrigerator.
When kept at the right temperature, eggs can often stay safe for about three to five weeks after the pack date. In some situations, they may even last a little longer.
Because of this, it is a good idea to check the freshness of eggs before deciding to throw them away.
There are a few simple methods that people have used for many years to test whether eggs are still good.
Learning these simple checks can help reduce food waste and also give you more confidence when preparing meals in your kitchen.
One of the easiest and most well-known ways to test egg freshness is called the float test. This method requires only a bowl of cold water and a few seconds of your time.
To do the test, gently place the egg in the bowl of water and watch how it behaves. The way the egg moves in the water can tell you a lot about its freshness.
If the egg sinks to the bottom and lies flat on its side, it is very fresh and perfectly good to use.
Eggs in this condition are usually ideal for most types of cooking and baking.
If the egg sinks but stands upright at the bottom of the bowl, it means the egg is older.
However, it is still generally safe to eat and can be used in many dishes. It may simply not be as fresh as a newly purchased egg.
On the other hand, if the egg floats to the top of the water, it is usually a sign that it has gone bad. In this case, the egg should be thrown away to avoid possible food poisoning.
The reason eggs float as they get older has to do with the structure of the eggshell. Eggshells have very tiny pores that allow air and moisture to pass through slowly.
As time goes by, a small amount of moisture inside the egg escapes while air enters through these pores.
As more air collects inside the egg, the air pocket becomes larger. This makes the egg lighter, and eventually it begins to float when placed in water.
Although the float test is very helpful, it is always wise to double-check the egg after cracking it open.
A fresh egg usually has a firm yolk and thick egg white, while a spoiled egg often has a strong unpleasant smell.
