How Long Are Eggs Good For?
Raw shell eggs generally keep 3–5 weeks refrigerated at 40°F (4°C) or below; hard-cooked eggs keep 1 week. FDA recommends using refrigerated eggs within 3 weeks for best quality.
| Egg form | Refrigerated storage | Freezing |
|---|---|---|
| Raw in shell | 3–5 weeks | Do not freeze in shell |
| Hard-cooked | 1 week | Poor texture after freezing |
| Separated raw whites or yolks | 2–4 days | Use an appropriate freezing method |
Label cooked eggs separately
A cooking-date label is the change I find most useful here. Raw shell eggs and hard-cooked eggs have different refrigerator windows, even when they came from one carton. Keep raw eggs in their carton so the package information stays available, and label the cooked batch with its own date. A float test cannot supply the missing safety information.
Quality guidance and storage guidance answer different questions
The 3–5 week reference for raw shell eggs comes from the US cold-storage chart. FDA gives a shorter three-week recommendation for best quality. These statements do not mean every egg becomes unsafe at one exact midnight or that storage conditions no longer matter.
For planning, use the earlier quality target when practical. Keep the carton so the purchase, packing, and product information remain available. A loose collection of eggs in a decorative bowl removes useful context without improving their storage.
A floating egg is not a bacterial test
An egg can float as its internal air cell enlarges. USDA explains that this reflects an older, lower-quality egg, but does not determine whether it is safe. The reverse is also true: sinking is not a certificate that an egg is free of harmful bacteria.
Skip the bowl-of-water decision ritual if the real question is an unknown storage history. You need to know whether the eggs stayed refrigerated and whether the shells were intact. A buoyancy observation cannot reconstruct a weekend spent on a warm counter.
Why US storage advice may differ from what you saw abroad
This guide concerns the US refrigerated egg supply. Handling systems and washing practices vary between countries, so seeing eggs sold unrefrigerated while traveling is not a reason to move US store-bought eggs to the counter.
Follow the instructions and cold-chain expectations for the product you actually purchased. Store eggs in their carton inside the refrigerator, where they are protected and identifiable. An appliance thermometer is more informative than assuming a refrigerator dial number corresponds to a particular temperature.
Once you crack them, change the label
Separated whites and yolks do not inherit the unopened shell egg's full remaining storage window. Put them into clean covered containers, label the separation date, and use the shorter guidance for that form.
A useful kitchen note includes quantity as well as date: two whites, three yolks, or beaten whole eggs. Otherwise a future recipe becomes a guessing exercise about both age and amount. Keep raw egg containers away from ready-to-eat ingredients and clean equipment after handling them.
Freezing works better outside the shell
Do not deliberately freeze eggs in their shells. For whole eggs, FDA advises beating yolks and whites together before freezing; whites can also be frozen separately. Yolks need more attention because their texture changes, so follow a dedicated preservation method for the intended use.
Freeze portions you can identify and thaw in the refrigerator. A frozen raw egg portion is still raw and needs appropriate preparation. Labeling a portion for baking does not itself make it suitable to eat uncooked.
One carton, two dates to track
Suppose you buy a carton and hard-cook six of its eggs a few days later. The remaining raw eggs still belong to the raw-shell-egg guidance. The six cooked eggs now need their own cooking date and the one-week hard-cooked window. Returning them to a familiar carton without marking them makes it easier to apply the wrong deadline.
I would use a separate labeled container or clearly identify the cooked portion. For eggs packed into a lunch, refrigeration at home is only part of the story: plan to keep the lunch cold too. If you are choosing the cooking method, the egg guide distinguishes the covered heat-off method from the boiling-water timer estimates.
FAQ
Does a floating egg always need to be discarded?
Floating indicates a larger air cell and an older egg, not a complete safety assessment. Do not use that observation alone to approve or reject an egg. Storage history, shell condition, and the relevant guidance matter; a sinking egg is not automatically safe either.
Are brown eggs stored differently from white eggs?
Shell color is not the basis of the refrigerated storage windows in this guide. Identify the product and its handling instructions instead. Keep eggs in their carton, maintain the recommended refrigerator temperature, and use the appropriate guidance for raw, separated, or cooked eggs.
Can I leave refrigerated eggs on the counter?
Do not use counter storage as the routine for US refrigerated eggs. Keep their cold chain intact and bring out only what you need for preparation. A travel memory of eggs displayed differently abroad does not establish that the product in your kitchen can be handled the same way.
Can I freeze leftover egg whites?
Yes, egg whites can be frozen separately using suitable packaging. Label how many whites or how much volume each portion contains and record the date. Thaw in the refrigerator and use them in an appropriate preparation; freezing does not turn raw egg into a ready-to-eat food.
Does peeling shorten the one-week hard-cooked limit?
The FDA one-week guidance covers hard-cooked eggs in the shell or peeled. Maintain clean handling and refrigeration in either case. Count from cooking, not peeling, and do not treat the shell as a reason to leave cooked eggs unrefrigerated or to extend the storage window.
