How long do eggs last?

Raw eggs in the shell keep 3 to 5 weeks in the fridge from the day you buy them. Hard-boiled eggs keep about 1 week, and raw whites or yolks 2 to 4 days.

Food	Fridge	Freezer
Raw eggs in the shell	3–5 weeksfrom purchase	Not recommended
Raw whites or yolks	2–4 days	12 months
Hard-boiled eggs	1 week	Not recommended

Fridge at 4 °C (40 °F) or colder, freezer at −18 °C (0 °F). Freezer times are for best quality: food kept frozen stays safe, but slowly loses taste and texture. These times are USDA guidance, not a guarantee. When in doubt, throw it out.

How to tell if eggs have gone bad

A sulfur or rotten smell when you crack the egg is the clearest sign. Throw it out.
A cracked, slimy or powdery shell: bacteria get in through cracks, so don't keep cracked eggs.
Pink, green, black or iridescent whites or yolks mean the egg has spoiled.
The float test (an old egg floats in water) shows age, not safety: the air pocket grows as the egg dries out. A floating egg can be fine and a sinking one can be spoiled, so trust your nose.

How to store eggs

Keep eggs in their carton on a shelf inside the fridge, not in the door, where the temperature changes every time it opens.
The carton protects the shells and stops eggs from picking up smells from other food.
Don't wash eggs before storing them. If one is dirty, wipe it just before you use it.
In the US, eggs are washed before sale and must stay refrigerated. In much of Europe they are sold unwashed and unrefrigerated, but the fridge still keeps them good for longer once you get them home.
Once eggs have been in the fridge, don't leave them out for more than 2 hours: a cold egg sweats at room temperature, which helps bacteria through the shell.
