Refrigerated eggs usually last 3–5 weeks, and many eggs remain usable beyond the sell-by date if they have been stored properly. The safest way to judge eggs is not by date alone, but by checking storage conditions, smell, appearance, and freshness tests.
This guide explains whether eggs expire, how long eggs last in the fridge, how to tell when eggs have gone bad, whether expired eggs are safe to eat, and how to compost bad eggs instead of throwing them away.
Quick Answer
Eggs do expire, but a printed date is not always the exact day they become unsafe. Raw eggs in the shell usually last 3–5 weeks in the fridge. Hard-boiled eggs last about 1 week. If an egg smells rotten, looks unusual, leaks, has mold, or floats during a freshness check, do not eat it. Compost bad eggs safely instead.

Do Eggs Expire?
Yes, eggs can expire. However, egg dates can be confusing because sell-by, best-by, and expiration dates do not always mean the same thing.
- Sell-by date: mainly for stores and inventory control.
- Best-by date: suggests peak quality, not necessarily safety.
- Expiration date: a stronger warning, but storage conditions still matter.
Eggs that have been refrigerated consistently can often remain usable beyond the printed date, but you should always check freshness before eating them.
The USDA explains that refrigerated eggs can generally be stored for several weeks. See the USDA guidance on how long eggs can be stored in the refrigerator.
Egg Shelf Life Table
| Egg Type | Fridge Life | Storage Notes |
|---|---|---|
| Raw eggs in the shell | 3–5 weeks | Store in the original carton inside the fridge. |
| Hard-boiled eggs | 1 week | Refrigerate promptly after cooking. |
| Beaten eggs | 2 days | Keep covered in a clean container. |
| Egg whites | 4 days | Store sealed and refrigerated. |
| Egg yolks | 2 days | Cover tightly; use quickly. |
How Long Do Eggs Last in the Fridge?
Raw eggs in the shell usually last 3–5 weeks in the refrigerator. They should be stored in their original carton, not loose in the fridge door.
Hard-boiled eggs last about 1 week in the fridge. Once eggs are cracked, beaten, or separated, their shelf life becomes much shorter.
The USDA also advises against storing eggs in the refrigerator door because the temperature changes more often there. Read the USDA's answer on whether it is safe to store eggs in the fridge door.
Not Sure If Your Eggs Are Still Safe?
If eggs smell rotten, look unusual, or fail freshness checks, do not risk eating them. GEME Terra 2 helps households compost spoiled food scraps indoors instead of sending them to the landfill.
How to Tell If Eggs Are Bad
The safest way to check eggs is to use several signs together: smell, appearance, shell condition, and freshness tests.
Signs an Egg Has Gone Bad
- Rotten smell: a sulfur-like odor is the clearest warning sign.
- Cracked or leaking shell: bacteria can enter through damage.
- Mold or powdery residue: discard the egg.
- Pink, green, or unusual egg white: do not eat it.
- Sloshing sound: may suggest the egg structure has broken down.
Never taste an egg to check if it is safe. If in doubt, throw it out or compost it safely.
Is the Egg Float Test Accurate?
The float test can help estimate egg age, but it is not a perfect food safety test. As eggs age, air enters through the shell, and the air cell grows larger. Older eggs may stand upright or float.
- Fresh egg: sinks and lies flat.
- Older egg: sinks but stands upright.
- Possibly bad egg: floats to the top.
A floating egg should be treated with caution. Even if an egg sinks, still check the smell and appearance after cracking.
Can You Eat Expired Eggs?
Sometimes. Eggs that are past the printed date may still be usable if they have been refrigerated properly and show no signs of spoilage.
However, do not eat eggs if they smell bad, look unusual, have cracked shells, or show signs of contamination. Egg safety matters because eggs can be associated with Salmonella risk.
The FDA provides food safety information about egg safety and Salmonella prevention.
Can You Compost Bad Eggs?
Yes, bad eggs and eggshells can be composted, but they should be handled carefully because they can smell and may attract pests in outdoor compost piles.
For outdoor composting, bury eggs deep in the pile and mix them with dry brown materials such as leaves, shredded cardboard, or sawdust. Eggshells can be crushed to help them break down faster.
What Parts of Eggs Can Be Composted?
- Eggshells
- Raw eggs
- Expired eggs
- Cooked plain eggs
- Small amounts of egg-based food waste
Turn Bad Eggs Into Compost Instead of Waste
Spoiled eggs can be unpleasant in outdoor bins, but indoor composting helps manage food scraps more cleanly. GEME Terra 2 is designed for kitchen food waste and continuous home composting.
How to Store Eggs Safely
Proper egg storage helps maintain quality and reduce food safety risk.
Egg Storage Do’s
- Store eggs in the original carton.
- Keep eggs in the main body of the fridge, not the door.
- Refrigerate eggs promptly after purchase.
- Label containers when storing cracked or separated eggs.
- Wash hands and utensils after handling raw eggs.
Egg Storage Don’ts
- Do not leave eggs at room temperature for long periods.
- Do not wash store-bought eggs before storing them.
- Do not use cracked or leaking eggs.
- Do not mix old and new eggs without tracking dates.
FAQ
How long do eggs last past the expiration date?
Eggs may last 2–3 weeks beyond a printed date if refrigerated properly, but you should always check freshness, smell, and appearance before using them.
Can you eat eggs that float in water?
A floating egg is old and may be spoiled. It is safest to discard or compost it, especially if it smells bad after cracking.
What happens if you eat a bad egg?
Eating a bad egg can cause foodborne illness, including nausea, vomiting, diarrhea, stomach cramps, and fever.
Can you eat eggs two weeks after expiration?
Possibly, if they have been refrigerated and pass smell and appearance checks. If there is any doubt, do not eat them.
How long do hard-boiled eggs last?
Hard-boiled eggs last about 1 week in the fridge, whether peeled or unpeeled.
Can you compost raw eggs?
Yes, raw eggs can be composted, but they should be buried deep in outdoor compost or processed in an enclosed composter to reduce odor and pest risk.
Are eggshells compostable?
Yes. Eggshells are compostable and add calcium-rich material to compost. Crushing them helps them break down faster.
Is the egg float test reliable?
The float test is useful for estimating age, but not perfect for safety. Always combine it with smell and visual checks.
