Eggs are a staple in many kitchens around the world. They are not only versatile and delicious but also packed with nutrients. However, one common question that arises for egg enthusiasts and casual cooks alike is: How long do eggs last in the refrigerator? Understanding egg storage, shelf life, and safety measures can ensure that we enjoy our eggs at their best and avoid any unnecessary food waste. In this article, we will explore the factors influencing egg freshness, best practices for storage, and how to determine if your eggs are still good to eat.
The Lifespan of Eggs: What You Need to Know
Eggs can have various expiration dates depending on multiple factors. The lifespan of eggs is typically influenced by:
1. The Grading and Packaging of Eggs
Eggs are usually graded based on their quality, and this grading affects how long they can last in the refrigerator:
Grade AA: These are the freshest eggs, with firm whites and intact yolks. They can last up to 3-5 weeks past the sell-by date.
Grade A: Slightly less fresh than Grade AA, these eggs still have decent quality and can also last for 3-5 weeks past the sell-by date.
Grade B: These eggs are usually used for baking and cooking and should be consumed within 2-4 weeks past the sell-by date.
2. Storage Conditions
How you store your eggs dramatically influences their longevity. To maximize freshness, keeping them in the refrigerator is key. Here are best practices for egg storage:
Keep them in the original carton: The carton helps reduce exposure to odors and protects the eggs from damage.
Store in the main body of the fridge: Avoid placing eggs in the door, as this area experiences more temperature fluctuations.
3. Temperature Maintenance
The ideal temperature for storing eggs is at or below 40°F (4°C). Eggs stored above this temperature will spoil more quickly.
Understanding Expiration Dates: Sell-By, Best Before, and Use By
When purchasing eggs, you’ll often see a series of dates on the carton. Here’s what they mean:
1. Sell-By Date
Defined by retailers, this informs consumers how long the eggs will remain at peak quality. However, eggs remain good for several weeks after this date if they have been stored correctly.
2. Best Before Date
This suggests the date until which the eggs will retain optimal flavor and texture, but it doesn’t necessarily indicate spoilage.
3. Use By Date
While similar to the sell-by and best-before, this date often signifies the last day the eggs should be used for quality assurance.
How to Determine If Your Eggs Are Still Good
When in doubt about whether your eggs are still safe to consume, there are a few simple tests you can conduct at home.
1. The Water Float Test
Fresh eggs sink in water, while older eggs tend to float. Here’s how it works:
- Fresh Egg: Sinks to the bottom and lays flat on its side.
- Slightly Older Egg: Stands upright on the bottom, but still sinks.
- Bad Egg: Floats to the top.
The floating happens due to an air cell that forms inside the egg over time, which increases in size as the egg ages.
2. The Sniff Test
A straightforward and effective way to determine freshness is by smelling the egg. If an egg has a foul odor when cracked open, it is best to discard it.
Storing Eggs for Longer Lifespan
To ensure your eggs stay fresh for as long as possible, consider the following methods:
1. Freezing Eggs
If you know you won’t consume your eggs within the fridge’s suggested time, you can freeze them. Here’s how:
- Crack the eggs into a bowl and whisk until blended.
- Pour the mixture into an ice cube tray or muffin tin.
- Freeze until solid, then transfer the eggs to a freezer-safe container for up to one year.
Freezing preserves your eggs without impacting quality significantly. Note that whole eggs, whites, and yolks can be frozen, but always consider adding a pinch of salt or sugar for yolks to prevent them from becoming gelatinous.
2. Pickling Eggs
This is another delightful method to extend the life of hard-boiled eggs. After boiling and peeling your eggs, place them in a jar and cover them with a vinegar-based solution. This not only prolongs the shelf life but also adds a unique flavor to them.
Signs of Spoilage: What to Avoid
Be vigilant! There are some telltale signs that will help you distinguish fresh eggs from spoiled ones. The following indicators suggest that eggs should be discarded:
1. Unusual Appearance
If the egg has a cracked shell, discolored yolk, or a slimy coat on its surface, it’s safer to toss it out.
2. Off-putting Odor
Crack your egg open away from your cooking area. If it emits a sulfurous, rotten scent, it’s definitely spoiled.
The Nutritional Value of Eggs
Before we wrap up, let’s take a moment to appreciate why eggs deserve a spot in your refrigerator, aside from their shelf life.
1. Packed with Protein
One large egg contains about 6 grams of protein, which is essential for muscle repair and overall body functionality.
2. Rich in Vitamins and Minerals
Eggs boast a variety of vitamins and minerals, including Vitamin B12, Vitamin D, and choline. These nutrients contribute to brain and heart health.
3. Versatile and Delicious
From breakfast omelets to baked goods, eggs can enhance flavor and texture in countless dishes.

How long do eggs last in the refrigerator?
Eggs can last quite a while in the refrigerator, typically up to three to five weeks beyond the purchase date. It’s essential to check the “best by” or “sell by” date on the carton; however, eggs can often remain fresh even after these dates if stored correctly. The cool temperature of the refrigerator helps prolong the freshness of eggs and slows down the growth of bacteria.
To maximize freshness, store eggs in their original carton on a middle shelf rather than the door, where temperature fluctuations are more common. Additionally, if you want to assess freshness, you can perform the water test: place an egg in a bowl of water; if it sinks to the bottom and lays flat, it’s fresh. If it stands upright or floats, it’s time to discard it.
Can you eat eggs past their expiration date?
Yes, in many cases, you can safely eat eggs past their expiration or “sell by” date. Eggs have a natural protective coating called the bloom that helps keep out bacteria and maintain freshness. If stored correctly in the refrigerator, eggs can remain safe for weeks after the indicated date, as long as they show no signs of spoilage.
However, it’s important to check if the eggs are still good before consuming them. This includes inspecting the eggs for any cracks or slimy surfaces and smelling them after cracking. If they produce an off odor or any unusual appearance, it’s best to err on the side of caution and discard them.
What is the best way to store eggs in the refrigerator?
The best way to store eggs in the refrigerator is to keep them in their original carton to protect them from absorbing strong odors and flavors from other foods. The carton also helps prevent the eggs from being jostled around, which can lead to cracks. Store eggs on a middle shelf, where the temperature is more consistent, rather than in the refrigerator door.
Additionally, ensure the refrigerator temperature is maintained below 40°F (4°C). This temperature slows down bacterial growth and helps keep eggs fresh longer. Avoid washing eggs before storage, as this can remove the protective coating and increase the risk of contamination.
How can you tell if eggs are still good?
To determine if eggs are still good, you can perform a simple float test. Fill a bowl with water and gently place the egg in it. If the egg sinks and lies flat on the bottom, it is still fresh. If it stands upright or floats, it indicates that the egg has likely gone bad and should be discarded.
Additionally, once you crack the egg open, look for signs of freshness. Fresh eggs will have a firm, intact yolk that sits high, while older eggs may have a flatter yolk that spreads out. If the egg emits a foul odor, it is spoiled and should not be consumed, regardless of its appearance.
Can you freeze eggs for long-term storage?
Yes, you can freeze eggs for long-term storage, but it’s important to do so correctly to maintain their quality. You can freeze whole eggs, egg whites, or egg yolks, but it’s not advisable to freeze them in their shells. Instead, beat the whole eggs lightly before pouring them into a freezer-safe container, or separate the yolks and whites accordingly.
When freezing eggs, be sure to leave some room in the container, as liquids expand when frozen. Frozen eggs can be stored for up to a year, although they are best used within four to six months for optimal quality. When you’re ready to use them, thaw frozen eggs in the refrigerator or use them in cooked dishes without defrosting.
What happens if you eat spoiled eggs?
Eating spoiled eggs can lead to foodborne illnesses due to bacteria such as Salmonella, which can be present in or on eggs. Symptoms of food poisoning from consuming bad eggs can include nausea, vomiting, abdominal cramps, and diarrhea, which can range from mild to severe. In some cases, it might even require medical attention, particularly for vulnerable groups like the elderly, young children, or individuals with weakened immune systems.
To minimize the risk of consuming spoiled eggs, always check for freshness before cooking them. It’s also wise to practice proper food safety by cooking eggs thoroughly, which can kill harmful bacteria. If in doubt about the freshness of your eggs, it’s always better to throw them out to avoid potential health risks.
