How to know if an egg is spoiled: (7 easy ways)

In this brief guide, we are going to answer the question “how to know if an egg is spoiled”, discuss the different methods of identifying spoiled eggs and the potential health effects of eating spoiled eggs.

How to know if an egg is spoiled:

There are several ways to determine if the egg is spoiled, such as checking if the expiry date has passed or not, see if it is giving any foul smell, see if the egg is cracked from somewhere or not. Shake the egg near your ear, listen to some sloshing sounds, and finally crack up the egg and see if there are any red spots inside it. If you see any such sign, it means that the egg is spoiled and is no longer safe to consume.

There are few signs from which we can find out if an egg is still edible or not. 

  • If the egg passes out, the expiry date written on the egg means that it’s not fresh anymore and not edible anymore.
  • Sniffing the egg:

If the egg gives a foul smell when we sniff it from its shell, open it and sniff from inside; if the egg still gives a foul odor, we should throw it away.

  • We should see if there is no crack or powder on the egg. If you see it, consider it a rotten egg.
  • If the egg is clear from outside, then crack it from and put it in a bowl, and check if there is any pink, blue, red, or other discoloration. If there are any such signs, then throw the egg.
  • Do a floating test on an egg. If the egg stinks in the bowl of water means that it’s fresh, but if it tilts up, then it’s not new anymore; it’s spoiled.
  • If we shake the egg near our ear and then hear a sloshing sound from inside, this means that it’s no longer edible. 
  • Crack the egg and see if there is any red blood-like spot on it; then, it’s spoiled and should not be eaten.

Let us explain these signs in detail ad see how these signs work:

Testing the egg for freshness:

Place the egg in the bowl of cold water and check to see if it floats or not. There is a fact about the egg that the egg contains a tiny pocket inside it, and as time passes, more air passes through the shell and into the egg. When more air enters the egg makes it more buoyant by the enormous growth of the pocket. 

  • Now check the egg. If the egg is laid on the bottom of the bowl it means that it’s too fresh.
  • If the egg is standing and pointing upward but still present on the bottom means that it’s not that fresh now but is still edible.
  • If the egg is floating on top of water it means that it’s not fresh anymore and should not be considered to eat it. Crack and smell it; if it smells terrible, then throw that away.

Quality test of egg white and yolk:

We need to crack the egg in an open plate or bowl and check its quality. Egg’s integrity changes as it starts getting older, and it can’t get hold together like a fresh one.

If the egg starts getting spread over means, it’s going toward spoiling, and if the egg shows watery and thinner white means it is fresh and can be eaten.

  • See if you notice that the yolk is flat and can break easily means the egg is old.
  • Notice if the egg yolk is moving around easily means that it is gone weak and getting older.
  • Now examine the color of egg white if it shows cloudy white, which means that it is fresh, but if it shows clear white standards that are not much new now, it is still edible.

Smelling the egg test:

Smelling the egg from the inside is the best indicator to find out the freshness of an egg. All you need to do is crack an egg on a plate and now smell it. A spoiled egg will give a pungent and bad smell after opening. This smell means that you need to throw that egg away immediately. The smell will continue even if it’s cooked.

Inspection of color:

The color of yolk has nothing to do with its freshness; it just depends on the hen’s diet. But the shade of egg white tells about the spoilage of the egg. If the yolk is pink in color it means that the egg is affected by Pseudomonas bacteria, and it’s not safe to eat anymore. Notice that green or black spots on the egg white mean that its fungus is affected. 

Tip to keep the egg safe:

We need to keep the egg in the refrigerator, and after the fridge, it should not be sat out at room temperature for more than 2 to 4 hours. Cool eggs in a hot temperature start getting sweat which begins the growth of bacteria outside the egg, and this can also go inside it and contaminate the whole egg. 

We need to refrigerate the egg and keep it cool, which prevents it from getting spoiled. 

It is unsafe to eat rotten egg:

Eating spoiled eggs causes salmonella injection, which causes diarrhea, vomiting, fever, blood in stools, abdominal cramps, and many other health issues. The person may get food poisoning. So make sure if the egg is fresh and safe to eat before eating.
