Pay Attention to This Date on Egg Cartons—It’s More Important Than You Think

You pick up a carton of eggs at the grocery store and notice a date printed on the package. It might say “Sell By,” “Best By,” “Use By,” or display another date code.

But what exactly does that date mean?

If you’ve ever stood in your kitchen wondering whether eggs are still safe to eat because the date on the carton has passed, you’re not alone.

Egg carton dates can be confusing because they don’t all mean the same thing. Some dates are intended to help stores manage inventory or indicate peak quality, while food-safety guidance focuses on factors such as proper refrigeration, handling, and how long eggs have been stored.

Understanding the date on your egg carton can help you reduce unnecessary food waste while making safer decisions about the eggs you eat.

Here’s what you should know before cracking that next egg.

Egg Carton Dates Don’t Always Mean “Unsafe After This Date”

One of the biggest misconceptions about egg carton dates is that an egg automatically becomes unsafe the day after the printed date.

That’s not necessarily true.

In the United States, egg carton dating rules can vary by state, and terms such as “Sell By” and “Best By” can have different purposes.

A “Sell By” date generally helps retailers know how long a product should remain available for sale. It isn’t necessarily a statement that the food becomes unsafe immediately afterward.

A “Best By” date is generally associated more with quality than an exact safety deadline.

However, this doesn’t mean you should ignore dates completely.

The date is one piece of information. Refrigeration, storage conditions, shell cleanliness, cracks, handling, and cooking practices also matter.

The Date You Should Pay Close Attention To

When you’re looking at an egg carton, don’t focus only on the most obvious date printed on the package.

Some cartons also include a three-digit Julian date, which indicates the day of the year when the eggs were packed.

For example, a code such as 001 represents January 1, while 365 represents December 31 in a non-leap year.

This packing date can provide useful information about how long the eggs have been in storage.

Egg cartons can also contain a plant identification number and other codes, depending on the labeling requirements where you live.

If you’re unsure what a particular code means, check the packaging information or contact the producer.

Why Egg Storage Matters So Much

Eggs are perishable foods.

Once eggs reach your refrigerator, keeping them consistently cold is one of the most important steps you can take to maintain quality and reduce the risk of foodborne illness.

The U.S. Food and Drug Administration recommends that eggs requiring refrigeration be stored at 40°F (4°C) or below.

Keeping eggs in their original carton can also help protect them from absorbing odors from other foods and makes it easier to keep track of the relevant dates.

Avoid storing eggs in the refrigerator door if possible. The temperature in the door can fluctuate more frequently than the temperature in the main refrigerator compartment.

What Does “Sell By” Mean?

The phrase “Sell By” can cause unnecessary confusion.

A sell-by date is primarily useful for retailers. It helps stores determine how long a product should be displayed for sale.

It isn’t necessarily a declaration that the eggs become unsafe immediately after that date.

If you have eggs at home that have passed the sell-by date, don’t automatically throw them away without considering how they’ve been stored.

If the eggs have been continuously refrigerated and are otherwise in good condition, they may still be usable.

However, local regulations and labeling requirements can differ, so always follow the guidance applicable to your location.

What Does “Best By” Mean?

A “Best By” or similar quality date generally indicates when the product is expected to have its best quality.

With eggs, quality can gradually decline during storage.

Older eggs may behave differently during cooking. For example, the whites may become thinner and the yolks may become less firm.

That doesn’t automatically mean the eggs are spoiled.

Still, quality and safety are separate considerations. An egg can lose freshness without necessarily being spoiled, while improper storage can create food-safety concerns.

What Does “Use By” Mean?

A “Use By” date can be more significant depending on the food and the labeling system used in your country.

Unlike “Best By,” which often refers primarily to quality, “Use By” may be used to communicate a stronger recommendation regarding when a perishable food should be consumed.

Because food-labeling laws differ between countries, consumers should check the meaning of the term used on their particular carton rather than assuming all date labels mean the same thing.

If you’re outside the United States, your country’s food-safety authority may provide specific guidance for egg labeling and storage.

How Long Do Eggs Usually Stay Fresh?

Properly refrigerated eggs can remain useful for a considerable period.

According to the USDA, shell eggs can generally be refrigerated for 3 to 5 weeks.

That doesn’t mean every egg will have identical quality throughout that period.

Egg quality gradually changes over time.

The most important factors include:

• How fresh the eggs were when purchased
• Whether they have been continuously refrigerated
• Whether the shells are cracked
• How they were handled
• Whether the eggs have been washed or processed according to local practices
• Whether the refrigerator maintains a safe temperature

The Smell Test Isn’t a Complete Safety Test

Many people crack an egg into a bowl and smell it to decide whether it’s safe.

A spoiled egg may have an unmistakably unpleasant odor, and you should discard eggs that clearly smell rotten after cracking.

But you shouldn’t rely solely on smell to determine whether an egg is safe.

Some harmful bacteria don’t necessarily produce an obvious smell, taste, or visible change.

This is why proper refrigeration, careful handling, and thorough cooking remain important.

What If an Egg Has a Cracked Shell?

Be cautious with cracked eggs.

The shell provides a natural barrier that helps protect the contents. A crack can create an opportunity for bacteria to enter.

If you notice a cracked egg in the carton before purchasing it, choose another carton.

If an egg becomes cracked at home, food-safety recommendations may differ depending on how and when the crack occurred. When in doubt, discarding it is the safer option.

Don’t buy cartons containing multiple visibly cracked eggs.

Should You Wash Eggs Before Putting Them in the Refrigerator?

This depends partly on where you live and how eggs are commercially processed.

In the United States, commercially sold eggs are washed and sanitized under regulated procedures before reaching consumers.

Consumers generally shouldn’t wash commercially prepared eggs before storing them because washing can potentially introduce contamination or remove protective characteristics of the shell surface.

In countries where eggs are sold unwashed, recommendations can differ.

This is one reason it’s important to follow food-safety guidance from your local authorities rather than applying advice from another country automatically.

How to Store Eggs Correctly

Good egg storage is surprisingly simple.

Keep eggs refrigerated

Store eggs at 40°F (4°C) or below when refrigeration is required.

Keep them in their original carton

The carton helps protect the eggs and provides important labeling information.

Store them in the main refrigerator compartment

The main compartment generally experiences fewer temperature fluctuations than the refrigerator door.

Keep the shells intact

Don’t use eggs with damaged or heavily cracked shells.

Wash your hands

Wash your hands with soap and water after handling raw eggs and before preparing other foods.

Clean surfaces

If raw egg spills onto countertops, cutting boards, utensils, or other surfaces, clean them thoroughly.

What About Hard-Boiled Eggs?

Hard-boiled eggs don’t have the same storage timeline as fresh shell eggs.

The USDA recommends using refrigerated hard-cooked eggs within one week after cooking.

Keep them refrigerated and avoid leaving them at room temperature for extended periods.

If you’re preparing eggs for a picnic, lunchbox, or gathering, use appropriate food-safety practices and keep perishable foods properly chilled.

Is It Safe to Eat Eggs After the Carton Date?

The answer depends on several factors.

Don’t treat a single date as the only deciding factor.

Instead, consider:

How were the eggs stored?

Were they continuously refrigerated?

Is the shell intact?

Cracks can increase the risk of contamination.

What does the date actually say?

“Sell By,” “Best By,” “Use By,” and packing dates serve different purposes.

Are there signs of spoilage?

An unusual appearance or strong rotten odor after cracking is a reason to discard the egg.

How will you prepare them?

Thorough cooking reduces the risk associated with certain foodborne pathogens.

For people who are more vulnerable to foodborne illness—such as young children, older adults, pregnant people, and individuals with weakened immune systems—extra caution with raw or undercooked eggs is especially important.

Why Cooking Eggs Properly Matters

Raw or undercooked eggs can carry Salmonella, a bacterium that can cause foodborne illness.

Symptoms can include diarrhea, fever, stomach cramps, nausea, and vomiting.

The FDA recommends cooking eggs until both the yolk and white are firm.

Recipes that use eggs without thorough cooking require additional care.

Examples can include certain homemade mayonnaise recipes, some desserts, and dishes containing partially cooked eggs.

If you’re preparing food for someone at higher risk of serious foodborne illness, consider using pasteurized eggs or egg products when appropriate.

Don’t Throw Away Eggs Just Because the Date Makes You Nervous

Food waste is a real concern, and misunderstanding date labels can contribute to unnecessary disposal.

If eggs have been properly refrigerated, are within the recommended storage period, and have no signs of spoilage, a date printed on the carton doesn’t necessarily tell the entire story.

At the same time, avoiding food waste should never mean taking unnecessary food-safety risks.

When you’re genuinely unsure about how an egg was stored or whether it has been compromised, the safest choice may be to discard it.

When in doubt, don’t taste a questionable egg to see whether it’s still good.

A Simple Egg Safety Checklist

Before using eggs, remember these basic habits:

• Check the carton date and understand what it represents.
• Look for cracked or damaged shells.
• Keep refrigerated eggs at 40°F (4°C) or below.
• Store eggs in their original carton.
• Keep eggs refrigerated rather than leaving them on the counter.
• Wash your hands after handling raw eggs.
• Clean surfaces that come into contact with raw egg.
• Cook eggs thoroughly when appropriate.
• Take extra precautions when serving people at higher risk from foodborne illness.
• When storage conditions are uncertain, choose the safer option.

Frequently Asked Questions

Can I eat eggs after the sell-by date?

A sell-by date is primarily intended for retail inventory management and doesn’t necessarily mean the eggs become unsafe immediately afterward.

Proper refrigeration and storage history are important. Follow applicable local food-safety guidance.

How can I tell if an egg is spoiled?

After cracking an egg into a separate bowl, an obviously rotten odor is a strong warning sign.

However, smell and appearance aren’t perfect tests for harmful bacteria, so proper storage and cooking practices remain essential.

Should eggs be stored in the refrigerator door?

It’s generally better to store refrigerated eggs in the main refrigerator compartment, where temperatures are more stable.

How long can hard-boiled eggs last?

Properly refrigerated hard-cooked eggs should generally be used within one week according to USDA guidance.

Can I freeze eggs?

Raw eggs in their shells should not be frozen because the liquid inside can expand and crack the shell.

If you want to freeze eggs, remove them from their shells first and use appropriate food-storage methods.

Final Thoughts

The date on an egg carton is important—but it isn’t the only thing that matters.

Terms such as “Sell By,” “Best By,” and “Use By” can serve different purposes, while packing codes can provide additional information about when eggs were processed or packaged.

More importantly, eggs are perishable foods, so proper refrigeration, careful handling, intact shells, and thorough cooking are essential parts of egg safety.

For many households, the best approach is simple: check the date, store eggs correctly, pay attention to their condition, and follow reliable food-safety guidance.

Understanding what that small printed date actually means can help you make smarter decisions, avoid unnecessary food waste, and keep your meals safer.

And the next time you reach for an egg carton, don’t just glance at the date—know what you’re actually looking at.
