How Long Do Eggs Last Before Going Bad?

Eggs are considered perishable in the United States. It implies they must be stored in the refrigerator to avoid spoilage. When properly preserved, eggs may survive for a surprisingly long period. Throwing away eggs as soon as their expiry date approaches may be a waste of money.

Eggs must be refrigerated in the United States and some other nations, including Australia, Japan, Sweden, and the Netherlands. It is because eggs in these nations are washed and sterilized immediately after they are laid to avoid Salmonella infection, which is often responsible for food poisoning from chicken products.

However, cleaning an egg may harm its naturally protective cuticle in addition to eradicating microorganisms. It may make germs migrate more easily through the shell and taint the egg.

Bacteria present within an egg is what finally causes it to “go bad,” or decay. Keeping an egg in the refrigerator (below 40°F, or 4°C) inhibits the development of germs and helps prevent them from piercing the shell.

Refrigeration is so good at limiting bacteria development that, when combined with an egg’s protective shell and enzymes, refrigerated eggs seldom go bad as long as they are handled and kept correctly.

Nonetheless, egg quality deteriorates with time. It causes the air pocket in an egg to expand, while the yolk and whites become thinner and less bouncy. It may eventually dry up instead of becoming rotten.

Despite these modifications, an egg may be entirely safe to consume for an extended period. On the other hand, eggs do not last forever and must be discarded at some time. This article will teach you all you need to know about the shelf life of eggs.

How Long Do Eggs Last?

So, how long do eggs stay fresh? Probably much longer than you imagine. If you don’t eat one egg every day and like to stretch your carton as far as possible, you’re in luck: Pasteurized eggs may be stored in the refrigerator for up to 5 weeks in their shells.

While the “Sell-By” date on the eggs usually expires within that time frame, as long as the eggs are refrigerated at 40°F or slightly below, they are fine to consume beyond the “Sell-By” date.

While in-shell eggs may keep for 3 to 5 weeks, frozen eggs can be kept for much longer. If you can’t complete a carton in time, separate the eggs from the shells, whisk them, and store them in a container. Frozen eggs may store for up to a year.

Various regulations apply to different kinds of eggs. Hard-boiled eggs have a shelf life of one week. And if you have a pasteurized liquid egg alternative, it will keep for ten days unopened or three days after opening.

How To Tell If An Egg Is Good Or Bad?

You want to make an omelet or brownies but aren’t sure whether the eggs in your refrigerator have been sitting too long. Eggs may lose some of their freshness with time, but they are still safe to use for many weeks. Here are numerous methods for determining if an egg is excellent or poor.

Check The Expiration Date:

Before taking eggs home from the supermarket, always check the expiry date or “sell by” date on the carton. Expiration dates cannot be more than 30 days from the day the eggs were placed into the carton. However, eggs may remain much longer.

Fresh eggs in the shell may survive three to five weeks if properly stored and refrigerated. The quality of an egg may begin to deteriorate as it ages, but it is still safe to consume.

Check The Pack Date:

You’ll also notice a three-digit number on the carton near the expiry date. It is the pack date, which is usually close to the plant number, which begins with the letter “P.”

Except in leap years, the pack date follows the Julian calendar, with 001 representing January 1 and 365 representing December 31. To rapidly translate the numbers on your carton, use the chart above. Fresh eggs in their cartons may be stored in the refrigerator for up to five weeks after this date.

Do A Sniff Test:

You may be able to determine whether your eggs have gone rotten merely by smelling them in your refrigerator. The easiest approach to do a smell test is to break an egg into a dish and examine it for an odd appearance or a poor odor. A rotten egg, whether raw or cooked, will smell terrible. It’s safe to use if it seems and smells normal.

Do an Egg Float Test:

When an egg is first laid, it lacks an air cell. However, when it cools, a pocket of air develops between the cell’s shell membranes at the big end of the egg. The yolk absorbs liquid from the egg white as the egg ages. More air enters the shell when moisture and carbon dioxide begin to evaporate via the pores in the egg, enabling that air cell to develop.

An egg float test may be used to determine the age of an egg by measuring the air pocket. Pour a glass of water over an uncooked egg.

• It’s fresh if it remains on the bottom of the glass horizontally.

• If it isn’t as fresh, it will slant slightly in a semi-horizontal posture.

• It will float to the top in a vertical posture if it is old and stale.

How To Properly Store Your Eggs?

Follow these basic guidelines to keep your eggs as fresh as possible.

Keep Your Fridge At The Proper Temperature:

Check your refrigerator to determine whether the temperature is at or below 40°F. The right temperature limits the development of germs within the egg, preventing it from spoiling. Items in your refrigerator are more prone to deteriorate or go bad if the temperature is too high.

Put Your Eggs In The Fridge As Soon As You Get Home:

After unloading groceries, do not leave your eggs on the kitchen counter. Storing them in the refrigerator right away to avoid spoilage. You don’t want them to be left at room temperature for too long.

Keep Eggs In The Back Of The Fridge:

It matters where you keep your eggs in the fridge. Keep them on an interior shelf near the back of the fridge in their original container. While many people like to store eggs on the fridge door, the temperature in the rear is more stable; they won’t keep as chilly owing to the door opening and shutting.

How To Use Older Eggs?

If your eggs aren’t the freshest but haven’t gone bad, there are a few things you can do with them. Similarly, there are several applications where fresh eggs are preferable.

Boiling older eggs is good. It becomes simpler to peel an egg as it matures and its air pocket expands. Older eggs are ideal for hard-boiled eggs, deviled eggs, and egg salad.

Older eggs may be used to make scrambled eggs, omelets, casseroles, and quiches. Fried eggs and poached eggs, on the other hand, should preferably be done using fresh eggs.

The longer an egg remains in the refrigerator, the runnier the yolk and whites get. Using an older egg may result in a runny mess rather than a solid fried egg or a compact poached egg.

Furthermore, an aged egg may not be as efficient as a leavening agent in baking. However, older eggs may utilize nearly anything. If you are unsure how long an egg has been sitting in the fridge, break it open and scent it first.


Eggs stored on the counter at ambient temperature ‘age’ faster than those kept refrigerated. One day on the counter is equivalent to one week in the refrigerator. You should not have a spoiling issue if you keep a few chickens and consume the eggs every day.

We hope you liked this free-range tour of fresh eggs. They are both healthful and tasty, and there is no comparison in terms of freshness or taste between your home-produced eggs and shop-purchased eggs.
