Lots of people wonder about keeping eggs fresh. Knowing how long do raw eggs last in the refrigerator is super handy, especially when you’re just starting out in the kitchen. It can seem a bit tricky to remember, but don’t worry!
This guide will give you a simple way to figure it out. We’ll go through everything you need to know so you can use your eggs with confidence.
How Long Do Raw Eggs Last In The Refrigerator
Fresh eggs are a staple in many kitchens. They are versatile and can be used in so many dishes, from baking to breakfast. But a common question that pops up is about their shelf life.
Specifically, many home cooks and bakers want to know how long do raw eggs last in the refrigerator. This is a practical piece of information that helps prevent food waste and ensures you’re using eggs that are safe and delicious to eat.
The shelf life of raw eggs can depend on a few things. The most important factors are how the eggs were stored initially and how they are handled once you bring them home. Understanding these aspects will give you a clearer picture of what to expect from your egg supply.
Understanding Egg Freshness
When you buy eggs from the grocery store, they have already been through a process. This process includes washing and grading. The washing removes any bacteria from the outside of the shell.
This is important because it helps the eggs last longer. However, it also removes a natural protective coating called the bloom. The bloom helps to keep bacteria from entering the egg through the shell’s pores.
Because the bloom is removed, U.S. eggs are typically kept refrigerated. In many other countries, eggs are not washed and retain their natural bloom.
These eggs are often stored at room temperature. This difference in processing is a key reason why storage recommendations can vary.
The Role of Refrigeration
Refrigeration is crucial for slowing down the growth of bacteria. This includes salmonella, which is a concern with raw eggs. Keeping eggs cold significantly extends their safe consumption period.
The ideal temperature for storing eggs is 40°F (4°C) or below. This is the standard temperature for most home refrigerators.
When eggs are stored correctly in the refrigerator, their quality is maintained for a longer time. This means the yolks stay centered, the whites are thick, and the overall taste remains good.
Determining Egg Shelf Life
So, how long do raw eggs last in the refrigerator? Generally, raw eggs can last for about 3 to 5 weeks when stored properly in the refrigerator. This is from the date they were purchased or packed.
There are a couple of ways to check the “best by” or “expiration” date on the carton. You might see a “sell by” date. This tells the store how long to display the product for sale.
Eggs are still good for a few weeks after this date.
You might also see a Julian date. This is a three-digit number that represents the day of the year the eggs were packed. For example, 001 would be January 1st, and 365 would be December 31st.
You can count forward from this date to estimate the packing date. Then, add the typical shelf life to find out when they might no longer be at their best.
The Float Test
One of the easiest and most popular ways to check if an egg is still fresh is the float test. This method relies on the air cell inside the egg. As an egg ages, the air cell gets larger.
This is because moisture evaporates through the shell, and air enters to replace it.
- Fill a bowl or glass with cold water.
- Gently place the raw egg into the water.
- Observe how the egg behaves.
If the egg sinks to the bottom and lies on its side, it is very fresh. If it sinks but stands on one end, it is still good but a few days or a week old. If the egg floats to the surface, it is likely too old to eat and should be discarded.
The float test is a good indicator of age, but it’s not the only way to tell if an egg has gone bad. Even if an egg sinks, it could still be spoiled. It’s always best to use your senses as well.
Sensory Checks for Spoilage
Before using an egg, it’s a good idea to perform a quick sensory check. This involves looking and smelling the egg. This is especially important if you’re unsure about the age of the egg or if it passed the float test but you still have doubts.
- Smell: A fresh egg has very little odor. A spoiled egg will have a distinct, unpleasant sulfurous smell. If you crack an egg open and it smells bad, throw it away immediately. This smell is usually quite noticeable.
- Look: When you crack a fresh egg onto a flat surface (like a plate), the yolk should be round and plump. The white should be thick and hold its shape around the yolk. If the yolk is flat and spreads out, or if the white is watery and thin, the egg is older but likely still safe if it passes the smell test. If you see any discoloration (pink, green, or rainbow sheen) in the white, discard the egg.
If an egg looks and smells fine, it is generally safe to use, even if it’s a bit past the typical 3-5 week window, as long as it was stored correctly. However, for best quality and taste, it’s good to use them within the recommended timeframe.
Proper Egg Storage Techniques
How you store your eggs can make a big difference in how long they stay fresh and safe. Following these simple storage tips will help you get the most out of your eggs.
Keep Them in Their Original Carton
Always store eggs in their original carton. The carton protects the eggs from absorbing odors from other foods in the refrigerator. It also prevents them from drying out.
The carton itself is designed to keep the eggs safe and stable.
Many people are tempted to store eggs in the door of the refrigerator. However, this is not ideal. The temperature in the refrigerator door fluctuates more than in the main body of the fridge, especially when the door is opened and closed frequently.
This variation in temperature can affect the eggs’ freshness.
It’s best to store the carton on one of the shelves in the main part of the refrigerator. This ensures a more consistent and colder temperature, which is key to preserving egg quality.
Store With the Wide End Up
When placing the carton on the shelf, orient it so that the wide end of the eggs is facing upwards. The air cell is located at the larger end of the egg. Storing eggs with the wide end up helps to keep the yolk centered within the white.
This can contribute to the egg’s overall freshness and appearance when cracked open.
Maintain Proper Refrigerator Temperature
As mentioned before, a refrigerator temperature of 40°F (4°C) or below is essential for keeping eggs fresh. If your refrigerator is warmer than this, it can accelerate spoilage. Periodically check your refrigerator’s temperature with a thermometer to ensure it’s set correctly.
What About Cracked Eggs?
If you find an egg with a cracked shell, it’s important to use it quickly. A crack in the shell can allow bacteria to enter the egg. It also increases the rate of moisture loss.
If the crack is small and the egg hasn’t leaked, you can still use it, but it’s best to cook it soon. For safety, it’s a good idea to crack any suspect eggs into a separate small bowl first. Then, check them for smell and appearance before adding them to your recipe.
If they seem off, you can discard that one egg without ruining the rest of your ingredients.
Freezing Eggs
Can you freeze raw eggs? Yes, you can! Freezing is a great way to preserve eggs for a very long time, usually for up to a year.
However, you cannot freeze eggs in their shells. The liquid inside the egg will expand as it freezes, causing the shells to crack.
To freeze eggs, you need to crack them and prepare them first:
- Whole Eggs: Crack whole eggs into a bowl, whisk them gently to break up the yolks and whites, but don’t beat them too much. Pour the mixture into freezer bags or ice cube trays.
- Egg Whites: You can freeze egg whites as they are.
- Egg Yolks: Egg yolks will become thick and gel-like when frozen. To prevent this, mix 1/8 teaspoon of corn syrup or salt (for savory dishes) or 1/2 teaspoon of sugar (for sweet dishes) into each cup of yolks before freezing. This helps maintain their texture.
Once frozen, label the containers with the date and the number of eggs or the type (whole, whites, yolks). Thaw frozen eggs in the refrigerator. Do not thaw them at room temperature.
Factors Affecting Egg Longevity
Several factors can influence how long raw eggs remain good in the refrigerator. Understanding these can help you make informed decisions about using your eggs.
The Age of the Eggs When Purchased
The “best by” or “sell by” date on the carton is a good indicator, but it’s not the absolute final word. Eggs sold in the U.S. are often quite fresh when they reach the store because they are refrigerated throughout the supply chain.
However, if you buy eggs that have already been on the shelf for a while, their usable life in your fridge will be shorter.
Storage Conditions at the Store
While most stores keep eggs refrigerated, there can be variations. If eggs were not stored at the proper temperature before you bought them, their shelf life might be compromised.
Handling After Purchase
Once you bring eggs home, how you store them matters. As discussed, keeping them in the original carton on a refrigerator shelf at a consistent cold temperature is key.
Common Misconceptions About Egg Freshness
There are a few common ideas about egg freshness that aren’t entirely accurate. Let’s clear them up.
The “Sell By” Date Means They Are Bad After That Date
This is a widespread misunderstanding. The “sell by” date is primarily for inventory management by retailers. It indicates the last day a product should be offered for sale.
Eggs are typically safe to consume for several weeks beyond their “sell by” date, provided they have been stored correctly.
Cracked Eggs Are Always Unsafe
A small crack doesn’t automatically mean an egg is spoiled. The key is how quickly it’s used and whether any spoilage indicators are present (bad smell, off-color). If the crack is recent and the egg looks and smells normal, it’s usually fine for cooking right away.
How to Use Older Eggs
Even if eggs are nearing the end of their prime, they can still be perfectly good for many dishes. Older eggs are actually easier to peel when hard-boiled! This is because the air cell has grown larger, which helps to separate the membrane from the shell.
Older eggs are also great for recipes where the egg is fully cooked and mixed into other ingredients, such as:
- Cakes and cookies
- Pancakes and waffles
- Scrambled eggs (where the yolk and white are mixed)
- Custards and puddings
- Quiches and frittatas
For dishes where the egg is the star or only lightly cooked, like poached or fried eggs, fresher eggs are generally preferred because their whites hold together better.
