How Long Raw Eggs Stay Fresh in Your Refrigerator

Raw eggs last three to five weeks in the refrigerator when stored properly, counting from the packing date on the carton

The packing date — a number from 1 to 365 printed on the carton — tells you when the eggs were graded and packed, not when they were laid. This date matters more than the "sell by" or "expiration" date because it gives you a real starting point. Eggs packed on day 1 are still safe to eat on day 35 if kept at a steady 40°F or below.

The reason eggs last this long is their natural protective layer, called the bloom or cuticle. This waxy coating seals the porous shell and slows moisture loss and bacterial entry. Once you wash an egg, you remove this layer, which is why store-bought eggs (washed before sale) last shorter than farm-fresh unwashed eggs. Keeping your refrigerator at the right temperature — between 35°F and 40°F — is what actually extends that window.

If you cannot find a packing date, count back from the sell-by date: most sell-by dates are set 30 days after packing. An egg with a sell-by date of day 60 was likely packed around day 30, so you have roughly two weeks left. This is an estimate, not a may provide, so when in doubt, use the float test or crack the egg into a bowl before cooking.

Key Takeaways

• The packing date on the carton, not the sell-by date, tells you when your eggs actually started their shelf life.
• Raw eggs in the shell stay safe for three to five weeks from the packing date if your refrigerator stays between 35°F and 40°F.
• Store eggs in their original carton on a shelf, not in the door, because the door is warmer and temperature fluctuates every time you open it.
• A raw egg that sinks and lies flat in cold water is fresh; one that stands upright or floats is older and should be cooked thoroughly or discarded.
• Cracked or visibly damaged eggs should be used within two days, and raw egg whites or yolks last only three to four days once separated.

Why the carton matters more than the date on the package

The carton itself is your best tool for storage. Eggs are porous, and they absorb odors and flavors from the air around them — onions, fish, and strong spices will transfer through the shell if eggs sit loose on a shelf. The carton holds them together, protects them from impact, and keeps them away from strong-smelling foods. It also slows water loss, which is why an egg in a carton stays fresher longer than one sitting bare in a bowl.

Keep the carton on a middle or lower shelf of your refrigerator, never in the door. The door is the warmest part of the fridge because it opens and closes constantly, letting warm air in. Temperature swings cause condensation to form on the shell, which can allow bacteria to enter through the pores. A steady, cool shelf is where eggs belong.

How to tell if a raw egg is still good

The float test is the quickest way to check an egg's age without cracking it. Fill a bowl with cold water and gently place the egg in it. A very fresh egg sinks and lies flat on the bottom. An older egg stands upright or bobs near the surface. A floating egg is past its prime and should be cooked thoroughly (not eaten raw) or thrown away.

This happens because as an egg ages, water inside evaporates through the porous shell, and the air cell at the wide end grows larger. The bigger the air pocket, the more buoyant the egg becomes. The float test does not tell you the exact age, but it tells you whether the egg is still in the safe window or approaching the edge.

If you crack an egg into a bowl, a fresh yolk will stand up tall and dome-shaped, and the white will be thick and cloudy. An older egg has a flat, runny yolk and thin, watery white. Smell it too — a fresh egg has almost no smell. Any sulfur or off odor means discard it. Trust your nose; it is more reliable than any date.

Storage rules for cracked or separated eggs

Once you crack an egg, the clock speeds up. Raw egg whites and yolks in a covered container last three to four days in the refrigerator. Raw whole eggs that have been cracked into a bowl should be used within two days. The shell was the barrier; without it, bacteria can grow faster.

Store separated whites and yolks in airtight containers, not in open bowls. Label them with the date you separated them. If you are storing yolks, cover them with a thin layer of cold water to prevent a skin from forming on top, which can dry them out. Change the water daily if you are keeping them longer than a day or two.

Cracked eggs with visible damage — a hole in the shell, a crack that goes all the way through, or a leak — should be cooked right away or discarded. A small hairline crack is usually fine if the egg has been refrigerated the whole time, but if it sat at room temperature, throw it out.

Temperature and humidity matter as much as time

Your refrigerator temperature is the single biggest factor in how long eggs last. At 40°F, eggs last the full three to five weeks. At 45°F, that window shrinks to two to three weeks. At 50°F or warmer, eggs age much faster and the risk of bacterial growth rises sharply. Check your refrigerator with a thermometer — many people assume theirs is cold enough when it is actually a few degrees too warm.

Humidity also plays a role. A very dry refrigerator will cause eggs to lose moisture faster through the shell, making them age quicker. If your fridge feels dry, you can place a small bowl of water on a shelf to raise the humidity slightly. This is not critical, but it can extend shelf life by a few days.

If you have a large number of eggs and do not use them quickly, consider storing some in the freezer. Crack them into ice cube trays, freeze them, then pop the cubes into a freezer bag. Frozen eggs last up to a year and work well for baking or scrambling, though the texture of the white changes slightly when thawed.

What happens if you eat an old egg

An egg that is past its safe window does not always look or smell bad. Salmonella and other bacteria can grow inside without visible signs. The risk is higher in raw or lightly cooked eggs — a runny yolk or soft white gives bacteria a better chance to survive. Cooking an egg thoroughly — until both the white and yolk are solid — kills most pathogens, which is why older eggs are safer cooked than raw.

Certain people should avoid raw or undercooked eggs altogether: young children, pregnant people, older adults, and anyone with a weakened immune system. For these groups, even a fresh egg carries some risk if eaten raw. If you are in one of these categories, cook all eggs until the yolk is firm.

If you do eat an old egg and get sick, symptoms usually appear within 6 to 72 hours and include nausea, vomiting, diarrhea, and stomach cramps. Most cases resolve on their own with rest and fluids. Seek medical care if symptoms are severe or last more than a few days.

Frequently Asked Questions

Can I eat an egg that floats in the float test?

A floating egg is old but not necessarily unsafe if cooked thoroughly. Cook it until both the white and yolk are completely solid. If you prefer to eat eggs raw or lightly cooked, discard it. When in doubt, crack it into a bowl and smell it first — trust your nose over the float test.

Do brown eggs last longer than white eggs?

No. Shell color does not affect how long an egg stays fresh. Brown and white eggs have the same porous structure and the same protective bloom. The difference is the breed of hen that laid it. Storage and temperature matter; color does not.

What if my refrigerator does not have a packing date on the carton?

Look for a sell-by date and count backward roughly 30 days to estimate when the eggs were packed. If there is no date at all, assume the eggs are older and use the float test before cooking. When possible, buy from stores that rotate stock frequently so you know the eggs are fresher.

Can I freeze raw eggs in the shell?

No. The liquid inside expands when frozen and will crack the shell, making them messy to thaw and potentially exposing the contents to bacteria. Crack eggs into ice cube trays or a container, freeze them, and thaw in the refrigerator before use. Frozen eggs work best for cooking, not for frying.

How do I know if my refrigerator is cold enough for eggs?

Use a refrigerator thermometer, available at any grocery or hardware store for a few dollars. Place it on a shelf (not in the door) and check it after a few hours. Your fridge should read between 35°F and 40°F. If it is warmer, adjust the dial and recheck after 24 hours.
