Most store bought eggs last 3 to 5 weeks from the day you buy them. That is much longer than most people think. The key is knowing how to store them and what signs to look for. This guide covers exactly how long eggs last, how to tell if they are still good, and what the science says about egg storage.
How Long Do Store Bought Eggs Last in the Refrigerator?
Store bought eggs in the refrigerator stay fresh for 3 to 5 weeks after purchase. The USDA states that eggs can be kept in the fridge for several weeks past the pack date and still be safe to eat. The “sell by” date on the carton is usually 30 days from when the eggs were packed.
Do not rely only on the date. Eggs often remain good for 2 to 3 weeks beyond that date if stored properly. The refrigerator temperature should be at or below 40°F. Keep eggs in their original carton on an inside shelf, not in the door. The door is the warmest part of the fridge and temperature changes every time you open it.
Fresh eggs last longer than older eggs. But even eggs near the end of their shelf life are safe as long as they are kept cold and the shell is intact. Cracked eggs should be used immediately or thrown away. Bacteria can enter through cracks even if the egg looks fine.
How Long Do Store Bought Eggs Last at Room Temperature?
Store bought eggs should not sit at room temperature for more than 2 hours. The USDA warns that eggs left out longer than that should be thrown away. This is because eggs in the US are washed and sanitized before sale, which removes a natural protective coating called the cuticle.
Without the cuticle, bacteria can enter the egg more easily through the porous shell. Room temperature allows bacteria to grow quickly. If you are cooking and leave eggs out while other ingredients come to room temperature, keep track of the time. Set a timer if needed.
Some countries do not wash eggs and leave the cuticle intact. Those eggs can sit at room temperature for weeks. But in the United States, store bought eggs require refrigeration from the moment they are washed. Do not take them out and leave them on the counter for later use.
| Storage Method | How Long They Last | Key Rule |
|---|---|---|
| Refrigerator (below 40°F) | 3 to 5 weeks past purchase | Keep in original carton on a shelf |
| Freezer (0°F or below) | Up to 1 year | Beat eggs before freezing; do not freeze in shell |
| Room temperature | No more than 2 hours | Discard after 2 hours |
How Can You Tell If Store Bought Eggs Are Still Good?
The float test is the most common method people use. Place the egg in a bowl of cold water. If it sinks and lies flat on its side, it is fresh. If it stands upright on the bottom, it is older but still safe to eat. If it floats to the top, it is likely spoiled and should be thrown away.
The science behind the float test is simple. Eggshells are porous. Over time, moisture and air move through the shell. As the egg ages, the air cell inside grows larger. A floating egg has a large air cell, which means it has lost moisture and is old. But the float test is not 100% reliable. An egg that floats might still be safe, though the quality will be poor.
A better way to check is to crack the egg into a bowl and look at it. Fresh egg whites are thick and sit close to the yolk. Older egg whites are thin and spread out. A spoiled egg will have a strong sulfur smell. If the smell is bad, do not eat it. Do not rely on smell alone for very old eggs. Some bacteria do not produce a smell but can still make you sick.
Another sign is the yolk. A fresh yolk sits high and round. An older yolk flattens out and breaks easily. If the yolk looks dull or the white has a greenish tint, the egg is still safe but past its prime for certain uses like poaching.
Does the Expiration Date on the Carton Really Matter?
The date on the carton is not a safety deadline. It is a quality indicator. The USDA requires a “sell by” date that is no more than 30 days after the eggs were packed. Eggs can still be sold after that date in many states, though some stores pull them earlier.
The pack date is more useful. It is a three-digit number printed on the carton that represents the day of the year. January 1 is 001, and December 31 is 365. If you see 032, the eggs were packed on February 1. The USDA says eggs are safe to eat for 4 to 5 weeks past that pack date.
Some cartons also have an expiration date. This is usually 30 days after the pack date. Eggs can be safe for another 2 to 3 weeks past this date if stored properly. Do not throw eggs away just because the date has passed. Use the float test and your senses instead.
One more thing: the date means nothing if the eggs were left out of the fridge for more than 2 hours. Temperature abuse shortens shelf life dramatically. If you buy eggs and leave them in a hot car for an hour, the clock starts ticking faster.
Can You Freeze Store Bought Eggs to Make Them Last Longer?
Yes, you can freeze eggs, but not in the shell. The liquid inside expands when frozen and the shell will crack. To freeze eggs, crack them into a bowl and beat them gently until the yolk and white are mixed. Pour the mixture into a freezer-safe container or an ice cube tray.
Frozen eggs last up to one year at 0°F or below. The quality is best if used within 6 months. Thaw frozen eggs in the refrigerator overnight. Use them in recipes where eggs are mixed with other ingredients, like scrambled eggs, omelets, or baked goods. Do not use thawed eggs for poaching or frying because the texture changes.
You can also freeze egg whites and yolks separately. Whites freeze well on their own. Yolks need a little salt or sugar stirred in to keep them from turning thick and gel-like. Label the container with the number of eggs and the date. This is useful if you buy eggs in bulk or have extra egg whites from a recipe.
Some people report that frozen eggs are not as good for baking. Research published in the Journal of Food Science found that freezing affects the protein structure in egg whites, which can change how they whip up. For recipes that rely on stiff peaks like meringue, fresh egg whites are better.
Common Misconceptions About Egg Storage
One common myth is that eggs should be washed before storing. Do not wash eggs. Store bought eggs are already washed at the processing plant. Washing them again removes the protective coating and increases the risk of bacteria entering through the shell. Keep them in the carton and wash your hands after handling raw eggs.
Another myth is that eggs should be stored with the pointy end down. This does not matter for safety. It might help the yolk stay centered, but the difference is small. Store eggs any way that fits in the carton. The carton itself protects the eggs from absorbing odors from other foods in the fridge.
Some people believe that brown eggs last longer than white eggs. The color of the shell has nothing to do with freshness. It only tells you the breed of the hen. Brown eggs and white eggs have the same shelf life if stored the same way.
A persistent myth is that eggs can be stored on the counter like in some European countries. This is not safe for US store bought eggs. The washing process makes refrigeration necessary. If you buy eggs from a local farm that does not wash them, they can sit at room temperature for a few weeks. But for standard grocery store eggs, keep them cold.

- Do not rely only on the expiration date
Frequently Asked Questions
Can you eat eggs 2 months after the expiration date?
It depends on storage. If eggs were kept at 40°F or below and pass the float test and smell test, they may be safe but quality will be poor. Most eggs lose quality well before 2 months past the date.
What happens if you eat a bad egg?
Eating a spoiled egg can cause food poisoning with symptoms like nausea, vomiting, stomach cramps, and diarrhea. Symptoms usually appear within 6 to 48 hours and last 1 to 2 days.
How long do hard boiled eggs last in the fridge?
Hard boiled eggs last up to one week in the refrigerator. Keep them in the shell for best quality. Peeled hard boiled eggs should be stored in a container with a damp paper towel and used within a few days.
Is it safe to eat eggs with blood spots?
Yes, blood spots are harmless. They are caused by a small blood vessel rupture during egg formation. You can remove the spot with a spoon or eat it without concern.
