How to tell if fresh eggs have gone bad

There are a few different methods to tell if an egg has gone bad that we are going to cover. Typically if one of these things is off then you should discard the egg.

With that said I would recommend checking all of these things to determine if you should cook with or eat the eggs. Just because they haven’t expired doesn’t mean that they won’t have a smell or have a crack in them.

Let’s go over just want you want to look for when deciding if your eggs are safe to eat or not.

Check the expiration date

Check the expiration date. You should always buy eggs within three weeks of their expiration date, and you should not eat eggs past the expiration date.

This is not a hard or fast rule with checking the expiration. You really want to follow the steps below.

Smell It

Eggs should have a neutral smell, no sulfurous, gassy, or sour notes. This is if the egg has not been cracked yet. However, the smell alone is an unreliable indicator of spoilage.

If you think an egg smells bad, it probably is and you should throw it away. Bad eggs will often have a characteristic smell that can be easily identified.

After you crack the egg if there is any bad odor then it is not good and should be thrown away. Eggs cracked that are fresh should not have a foul smell at all.

Look it over

 While the egg is still in an eggshell, check that it’s not cracked, slimy or powdery. A slime or crack in the eggshell could indicate signs of bacteria in the egg.

A bad egg may have white spots on the shell.

After you crack the egg if you see red color or black then this is a good sign that it is no good and it should be tossed. The yolk should be a vibrant yellow or orange color.

The whites of the egg should be clear and have no odd colors.

Shake the egg

There is a good chance that the egg has gone bad if you shake it gently and make a sloshing or rattling noise inside.

A fresh egg won’t make any noise at all when shaken.

Float test

A good way to tell if an egg is bad, or about to go bad, is by doing a float test. Fill 3/4 of a glass with water and then add an egg.

A fresh egg will sink to the bottom of the bowl and lay on its side.

However, if the egg floats, it means that the air cell has grown large enough that buoyancy has taken over gravity and it is no longer dense enough to sink.

This generally means that the egg isn’t good for consumption anymore and should be discarded.
