Eggs do not go bad suddenly in the fridge, but they do lose quality over time. A fresh egg stored properly in the refrigerator can stay safe to eat for weeks past the date on the carton. The real question is not whether they go bad, but how to tell when they have actually turned.
How Long Do Eggs Last in the Fridge?
The USDA states that eggs can be stored in the refrigerator for 3 to 5 weeks from the day you buy them. That date on the carton is a sell-by date, not a safety deadline. If you bring eggs home and put them in the fridge right away, they will likely be fine for several weeks after that date passes.
Fresh shell eggs have a natural coating called the bloom that keeps bacteria out. Washing removes this coating, which is why eggs in the US are refrigerated while eggs in some other countries are not. Once refrigerated, eggs must stay cold. Leaving them on the counter for two hours or more creates risk.
Hard-boiled eggs are a different story. They last about one week in the fridge. The cooking process removes the protective bloom, so bacteria can enter the shell more easily.
Can You Eat Eggs After the Expiration Date?
Yes, in most cases. The expiration date on an egg carton is not a safety cutoff. It is a quality estimate set by the producer. Research from the USDA shows that eggs can remain safe to eat for 3 to 5 weeks after you buy them, even if the date on the carton has passed.
The key is proper storage. Eggs kept at a steady 40°F or below in the main body of the refrigerator — not the door — will last longer. The door opens and closes often, causing temperature swings that speed up spoilage. Store eggs on a middle or lower shelf instead.
Do not rely on the date alone. A bad egg will give you clear signs before it becomes dangerous. The date is a starting point, not a final answer.
How to Tell If an Egg Is Bad
Your senses are the best tools for checking egg freshness. The float test is widely shared online, but it has limits. A fresh egg sinks to the bottom of a bowl of water and lies flat. An older egg stands upright or floats. The float test tells you about age, not safety. A floating egg is not necessarily bad — it just has more air inside from moisture loss over time.
The smell test is more reliable. Crack the egg into a clean bowl. If it smells like sulfur or rot, throw it away. A fresh egg has almost no smell. Also look at the white and yolk. A fresh egg white is thick and cloudy. The yolk sits high and round. An older egg white is thin and runny, and the yolk flattens out. These changes are normal and do not mean the egg is unsafe.
If the egg white has a greenish tint or the yolk sticks to the shell in a way that looks odd, that can be a sign of bacterial growth. When in doubt, toss it. The cost of one egg is not worth the risk.
Do Eggs Go Bad In The Fridge Faster After Washing?
Yes, washing eggs shortens their fridge life. Commercial egg washing is required in the United States for safety reasons. It removes dirt and bacteria from the shell, but it also strips the protective bloom. That is why the USDA requires eggs to be refrigerated from that point forward.
If you wash eggs at home, you remove the bloom again. This makes the shell more porous and allows bacteria and moisture to move in and out more easily. Washed eggs spoil faster than unwashed ones, even in the fridge.
Do not wash eggs until you are ready to use them. If there is visible dirt on a store-bought egg, it is rare but possible. Wipe it off with a dry cloth instead of running it under water. For farm-fresh eggs with visible debris, wash them right before cracking, not before storing.
What About Egg Safety and Salmonella?
Salmonella is the main safety concern with eggs. The CDC estimates that about 1 in 20,000 eggs contains Salmonella. That number is low, but the risk is real, especially for young children, older adults, pregnant women, and people with weakened immune systems.
Refrigeration slows bacterial growth but does not kill Salmonella. If an egg starts out contaminated, it stays contaminated. Proper cooking kills Salmonella. The USDA recommends cooking eggs until both the white and yolk are firm. For dishes that combine eggs with other ingredients, cook to an internal temperature of 160°F.
Do not rely on the fridge to make a bad egg safe. The fridge extends shelf life and slows spoilage, but it does not fix contamination that was already there. Buy eggs from a reputable source. Check for cracks before buying. If a shell cracks on the way home, use that egg within two days and cook it fully.
| Egg Type | Fridge Storage Time | Key Safety Note |
|---|---|---|
| Fresh shell eggs | 3 to 5 weeks from purchase | Keep at 40°F or below |
| Hard-boiled eggs | 1 week | Store in shell or peeled |
| Raw egg whites | 2 to 4 days | Use airtight container |
| Raw egg yolks | 2 to 4 days | Cover with water to prevent drying |
| Leftover egg dishes | 3 to 4 days | Reheat to 165°F |
Common Misconceptions About Egg Storage
One common myth is that eggs must be stored with the pointy end down. This is not true for safety. Pointy end down keeps the yolk centered, which helps with appearance but not with spoilage. Store eggs however they fit best in your fridge.
Another myth is that brown eggs last longer than white eggs. Shell color comes from the breed of the hen and has nothing to do with freshness or shelf life. A brown egg and a white egg from the same farm will spoil at the same rate under the same conditions.
Some people believe that eggs should be left at room temperature before cooking for better texture. This is a cooking preference, not a safety rule. If you do this, do not leave eggs out for more than two hours. The USDA warns against leaving eggs at room temperature for longer than that because bacteria multiply quickly between 40°F and 140°F.
There is also a belief that you can freeze eggs in the shell. Do not do this. The liquid inside expands as it freezes, which cracks the shell and makes the egg unsafe. If you want to freeze eggs, crack them into a bowl, beat them until blended, and pour them into a freezer-safe container. Label it with the date and use within one year.
Frequently Asked Questions
Can you eat eggs 2 months out of date?
Possibly, but it depends on storage conditions. If kept at a steady 40°F or below, eggs can sometimes be safe past two months, but quality will be poor.
What does a bad egg look like when cracked?
A bad egg may have a greenish or pinkish tint in the white, or the yolk may look flat and break easily. A strong sulfur smell confirms it is spoiled.
Is the float test accurate for egg safety?
Not completely. The float test measures age, not safety. A floating egg is older but can still be safe if it passes the smell test.
Can you get sick from eating old eggs?
Yes, if they contain Salmonella or other bacteria. Old eggs are more porous and more likely to harbor bacteria, so always check for signs of spoilage before eating.
