The Importance of Knowing If Eggs are Good

Challenger, welcome to our article on how to tell if eggs are good. The ability to determine if an egg is good or bad is a valuable skill for any chef or home cook. Consuming an expired or spoiled egg can cause severe health issues, including food poisoning. Therefore, it is crucial to understand the different methods to identify good eggs to avoid any health hazards.

In this article, we will be focusing on the various ways to identify if an egg is good or not. We will also be answering some common questions on this topic. By the end of this article, you will have a comprehensive understanding of how to tell if an egg is good or bad.

Factors that Affect Egg Quality

Before we begin exploring the different ways to identify good eggs, it is essential first to understand the factors that impact the quality of an egg.

One of the most important factors is the freshness of the egg. An egg loses its freshness as time passes, which results in a decline in quality. As the egg ages, the egg white becomes thinner and the yolk becomes flatter, which makes it harder to identify if the egg is good.

The storage of the egg also plays an important role in its quality. If the egg is stored in high temperatures or is exposed to sunlight, it can cause the egg to deteriorate faster, leading to spoilage. High humidity can also damage the eggshell, which can result in bacteria entering the egg.

The breed of the chicken that laid the egg can also affect its quality. Different breeds of chicken produce eggs of varying size, texture, and color. The diet of the chicken can also impact the quality of the egg it produces.

Now that we have a basic understanding of the factors that impact egg quality, let us move on to the methods of identifying good eggs.

Using the Float Test

The float test is one of the easiest and most popular ways to identify if an egg is good or bad. To perform the float test, fill a bowl with water and gently place the egg in the water. If the egg sinks to the bottom and lies flat on its side, it is fresh. If the egg starts to tilt upwards or stands on its end, it is not fresh and may be bad.

The float test works because, over time, an egg will lose moisture through its porous shell, which results in a larger air pocket inside the egg. The more prominent the air pocket, the more likely it is that the egg is bad and has spoiled.

Is it safe to eat a floating egg?

An egg that floats in water should not be consumed, as it is likely that the egg has gone bad. Eating a bad egg can result in food poisoning and cause several health issues.

The Candle Test

The candle test is another common way to identify if an egg is good or not. The candle test involves using a bright light source to illuminate the egg and observe its contents.

To perform the candle test, simply hold the egg up to a bright light source, such as a flashlight or a candle. If the egg is fresh, it will appear opaque, and you will not be able to see through the egg. If the egg has started to spoil, it will appear translucent or transparent, and you may be able to see the yolk or white inside the egg.

What can affect the accuracy of the candle test?

Artificial light can affect the accuracy of the test. It is best to use natural daylight to perform the candle test for the most accurate results.

The Crack Test

The crack test is another easy way to determine if an egg is good or not. To perform the crack test, simply crack the egg open onto a plate or bowl. If the egg is fresh, the yolk and white should be firm, and the egg should have a thick consistency. If the egg is bad, the yolk and white will be runny, and the egg will have a thin consistency.

What if the egg looks and smells normal but fails the crack test?

If the egg looks and smells normal but fails the crack test, it is best to discard the egg. It is better to be safe than sorry, as consuming a bad egg can result in food poisoning.

The Smell Test

The smell test is another method to determine if an egg is good or bad. If an egg has started to go bad, it will emit a rotten odor.

To perform the smell test, hold the egg close to your nose and take a whiff. If the egg smells fresh, it is most likely good to eat. If the egg smells bad, it has gone bad and should be discarded.

Can I still use an egg that smells a little off?

No, even if an egg smells slightly off, it is best to discard it. Consuming bad eggs can cause food poisoning and pose a significant health risk.

Other Methods to Identify Bad Eggs

There are other ways to identify if an egg is bad, such as checking the eggshell for cracks or discoloration, or shaking the egg to see if the yolk moves freely. However, these methods are not as accurate as the previous methods and may not provide a definitive answer.


We hope this article has provided you with valuable information on how to identify if eggs are good or bad. It is essential to be able to determine if an egg is good to avoid any health hazards that may arise from consuming spoiled eggs.

Remember to use the float test, the candle test, the crack test, and the smell test to determine if an egg is good or bad. If you are unsure, it is best to err on the side of caution and discard the egg.
