Eggs are a versatile and nutritious food that can be enjoyed in many different ways, from omelets and quiches to cakes and cookies. However, it’s important to make sure that the eggs you consume are fresh and safe to eat. 

Eggs that have gone bad can be a breeding ground for bacteria and can pose a risk to your health if consumed. But how can you tell if an egg has gone bad? In this blog post, we will discuss how to tell if eggs are bad and share some tips on how to properly store and handle eggs to help ensure their freshness and safety. 

Factors that Affect Egg Freshness 

The freshness of eggs depends on various factors, including the age of the egg, storage conditions, and handling practices.

Age of the egg: As an egg ages, it loses moisture, and the air sac inside it grows larger. As a result, the egg becomes less fresh. A fresh egg will have a yolk that sits high, and the white will be thick and close to the yolk. An older egg will have a flatter yolk and thinner, more watery white.

Storage conditions: The temperature and humidity of the environment in which the eggs are stored can affect their freshness. Eggs should be stored in a cool, dry place. If the temperature is too warm, the eggs can spoil faster. If the humidity is too high, the eggs can absorb moisture and become moldy.

Handling practices: Eggs are delicate and can be easily damaged, which can affect their freshness. Cracks or other damage to the shell can allow bacteria to enter the egg, causing it to spoil more quickly. Therefore, it’s important to handle eggs carefully and avoid dropping or shaking them.

How to Tell if Eggs are Bad: Signs of a Bad Egg 

There are several signs to look for to determine if an egg is bad.

Appearance: If an egg is bad, the shell may be discolored or dirty. When you crack the egg open, the yolk and white may appear runny, watery, or discolored. A bad egg may also have a flat yolk and a thin, transparent white.

Smell: One of the most noticeable signs of a bad egg is a foul odor. If the egg smells bad, it’s likely spoiled.

Float Test: The float test is a simple way to determine if an egg is bad. Fill a bowl with cold water and gently place the egg in the water. If the egg sinks to the bottom and lies flat on its side, it’s fresh. If it sinks but stands on its end, it’s a few days old but still good to eat. If the egg floats to the top, it’s gone bad and should be discarded.

How to Properly Store Eggs 

Proper storage is key to keeping eggs fresh. Here are some of the things you can follow to keep the eggs fresh:

Refrigeration: Eggs should be stored in the refrigerator, ideally in the main body of the fridge rather than the door. The temperature of the fridge should be between 33 and 40 degrees Fahrenheit. Storing eggs in the fridge helps to slow down the growth of bacteria and prolong the freshness of the eggs.

Egg carton orientation: Eggs should be stored with the pointed end facing down. This helps to keep the yolk centered and prevents it from coming into contact with the air sac, which can cause it to deteriorate more quickly.

Separating yolks and whites: If you’re not going to use the whole egg, it’s best to separate the yolks and whites and store them in separate containers. This helps to prevent the egg from spoiling as quickly and makes it easier to use the yolks or whites for different recipes.


Knowing how to tell if eggs are bad and how to properly store them is an essential skill for any home cook. By following these tips, you can help ensure that your eggs are always fresh, safe, and delicious. Whether you’re making an omelet for breakfast or baking a cake, fresh eggs are an important ingredient that can make all the difference in the final product. So next time you’re in the grocery store, remember to check the freshness of the eggs before you buy them, and always store them properly at home to keep them fresh and safe to eat.


How long do eggs typically last before they go bad?

The shelf life of eggs can vary depending on several factors, including how they are stored and whether they have been cooked. Eggs generally last up to 5 weeks when stored in the refrigerator. However, it’s important to note that the expiration date on the carton is only an estimate and not always accurate. It’s always a good idea to check the freshness of an egg before consuming it.

What is the float test, and how can it be used to check the freshness of an egg?

The float test is a simple method for determining whether an egg is still fresh. To perform the test, place the egg in a bowl of water. If the egg sinks to the bottom and lays flat on its side, it is still fresh. If it stands upright on the bottom or floats to the top, it is likely no longer fresh and should be discarded. As an egg age, the air pocket inside it gets larger, causing it to become less dense and more buoyant in water.
