Common Spoilage Signs Of Eggs

Many among us often deal with an older egg that looks fine from the outside. It is important to determine an egg’s freshness before you consume it. So, let us now first learn how to know if eggs are good in the water.

  1. Float Test

You can do an egg float test for egg freshness. For this, simply take a glass or bowl filled with cold water and place your egg into this cold water. Wait for a while and keep an eye on your egg movements. If your egg sinks to the button and lay flat on its side, it is still fresh. Even if your egg stays at the bottom but stands on one end, it can be consumed. Spoiled eggs will float to the surface, so it’s better to discard them!

  1. Smell

Apart from the water test, you can also tell if an egg is good by its smell. Fresh eggs have little to no noticeable odor. If you get a pungent smell from your eggs, they are no longer safer to eat. Sometimes, you might also get a sulphuric, gassy, or sour smell from eggs. Eggs often develop cracks during transportation. Due to these cracks, bacteria get a chance to enter through the shell and develop an odor inside the egg.

  1. Appearance

It is very important to know what does a bad egg look like while it is still in the shell. When you notice it has a slimy or powdery exterior, they are contaminated by bacteria or mold. You can also take a look at the inside of the eggshell after cracking it up. If you notice black or brown spots, it is no longer fresh.

After you crack an egg onto a flat surface, you must also observe its yolk and egg white. Fresh eggs will always have a bright yellow or orange yolk. And the egg white is slightly stiff and will sit up around the yolk. However, the egg white of the spoiled egg will be flatter and spread out.

  1. Shake It

Alternatively, you can also hold an egg up to your ear and shake it. Fresh eggs won’t make any noise. On the other hand, the egg is no longer good if you hear the liquid swishing around inside. This swishing sound indicates that the egg is very old and has a watery yolk.

  1. Check The Expiry Date

While purchasing eggs from the grocery store, you must check the use-by date on the carton. The sell-by date indicates how long a store should sell the eggs. While the use-by date indicates the date after which the eggs are considered less than fresh. If your eggs are passed the expiry date, you can still eat them only if they are refrigerated.

Now, you must be wondering how do you know if an egg is bad after boiling it. Hard-boiled eggs have shorter shelf life than raw eggs. Boiled eggs are more prone to bacteria and other contaminants. If you notice a slimy or chalky texture on your egg, simply discard it.
