Eggs are a staple in many households, known for their versatility and long shelf life. But what happens when they go past their expiration date? Specifically, can you still eat eggs that expired a month ago? In this article, we’ll explore everything you need to know about expired eggs, how to check if they’re still good to eat, and the risks involved.
Understanding Egg Expiration Dates
Before we dive into whether you can eat eggs that expired a month ago, it’s important to understand how egg expiration dates work.
Eggs typically have a “sell by” or “expiration” date printed on the carton. This is meant to guide consumers on the freshness of the eggs. However, it’s not a guarantee that the eggs are unsafe to eat the day after the expiration date.
The expiration date is based on how long eggs will stay fresh in their best quality. In most cases, eggs can still be good to eat for several weeks after the expiration date if stored properly.
How Long Do Eggs Last?
Eggs have a relatively long shelf life compared to many other perishable foods. The general rule of thumb is:
- Fresh eggs, when stored properly in the fridge, can last for 3–5 weeks beyond their sell-by date.
- Hard-boiled eggs, once cooked, typically last up to one week in the fridge.
- Eggs in the shell may last longer if kept in the fridge, but you should always check for freshness before consuming.
Eggs that have been stored in a cool, consistent environment will stay fresh longer. Eggs stored at room temperature will spoil much faster, so it’s always best to refrigerate them.
How to Check If Your Eggs Are Still Good
Even if the eggs in your fridge are past their expiration date, there are simple ways to check if they are still safe to eat.
1. The Float Test
One of the easiest ways to check the freshness of an egg is the float test. Here’s how to do it:
- Fill a bowl with water deep enough to fully submerge the egg.
- Gently place the egg in the water.
- If the egg sinks to the bottom and lays flat on its side, it is still fresh.
- If the egg stands upright or floats, it is likely spoiled and should be discarded.
Why does this work? As eggs age, air enters the shell and the egg becomes less dense. An older egg has a larger air pocket, which causes it to float in the water.
2. The Sniff Test
Another reliable method for checking the freshness of an egg is to crack it open and smell it. A fresh egg will have little to no odor. If the egg smells sour or rotten, it should not be eaten. The presence of an unpleasant smell is a clear sign that bacteria have begun to grow inside.
3. The Visual Check
When you crack an egg open, take a look at the egg white and yolk. A fresh egg will have a firm, slightly thick white that surrounds a bright, firm yolk. If the egg white is runny, watery, or the yolk is broken and flat, this may indicate that the egg is no longer fresh.
4. The Shake Test
You can also shake the egg gently and listen for sloshing sounds. If you hear liquid moving around inside the egg, it means the egg has aged, and the egg white and yolk have thinned. While this doesn’t necessarily mean the egg is spoiled, it’s a sign that it’s past its prime and may not be ideal for all types of cooking.
Can I Eat Eggs That Expired a Month Ago?
Now that you know how to check the freshness of eggs, let’s discuss whether it’s safe to eat eggs that have expired a month ago.
Factors to Consider:
How the Eggs Were Stored
If the eggs have been stored in the fridge the whole time, and the carton was not opened, the eggs could still be good even a month after the expiration date. Eggs tend to stay fresh longer when kept at a consistent temperature and not exposed to fluctuating heat.
Expiration Date vs. Sell-By Date
The expiration date is often a guideline for optimal quality, but it doesn’t necessarily mean that eggs go bad on that date. In fact, eggs can last a month or more beyond their expiration date if they’ve been kept at the right temperature. Just make sure you check the eggs carefully before eating them.
The Condition of the Eggs
If the eggs are still intact, and the float test, sniff test, and visual check all come back fine, the eggs are likely safe to eat. However, eggs that show signs of being cracked or leaking should not be consumed, as they can easily harbor bacteria.
Cooking the Eggs
Even if your eggs are a month past the expiration date but pass all the freshness tests, it’s best to cook them thoroughly before eating. Cooking eggs to a safe temperature (160°F or 71°C) will help kill any harmful bacteria, such as Salmonella, that may have developed over time.
Risks of Eating Expired Eggs
While many eggs are still good after their expiration date, there are risks involved in eating eggs that are a month past their expiration. Here are some of the potential risks:
1. Foodborne Illness
Eggs are a high-risk food when it comes to foodborne illness. The bacteria Salmonella is most commonly associated with raw or undercooked eggs. While cooking eggs thoroughly can kill the bacteria, there’s still a small chance that expired eggs could harbor harmful bacteria, even if they look and smell okay.
If you experience symptoms such as stomach cramps, nausea, vomiting, or diarrhea after eating expired eggs, you should seek medical attention.
2. Increased Risk of Spoilage
As eggs age, the likelihood of them spoiling or becoming contaminated increases. Bacteria can enter the eggshell, especially if the eggs are cracked or exposed to dirt or moisture. This can lead to contamination inside the egg, which could make you sick even if the egg doesn’t show obvious signs of spoilage.
3. Decreased Nutritional Value
Even if expired eggs don’t cause illness, they may lose some of their nutritional value. Older eggs tend to have lower protein quality and reduced levels of certain nutrients. While they might not be harmful to eat, they may not be as beneficial as fresher eggs.
When to Toss Eggs
There are a few scenarios where you should definitely toss eggs, even if they are a month past their expiration:
- If they float in the water during the float test, indicating that they are very old.
- If they have an off smell when cracked open, indicating that they are rotten.
- If the egg shell is cracked or damaged.
- If there is any leaking liquid or evidence of bacterial contamination.
In any of these cases, it’s better to be safe than sorry and discard the eggs.
Tips for Storing Eggs Properly
To extend the shelf life of your eggs and keep them safe to eat longer, follow these storage tips:
Store eggs in the coldest part of your fridge (usually the back) rather than on the door, where the temperature fluctuates.
Keep eggs in their original carton to prevent them from absorbing odors from other foods and to help maintain their moisture level.
Don’t wash eggs before storing them, as the protective coating on the shell helps keep bacteria out.
Check expiration dates regularly, but always test the freshness of eggs before consuming them, even if the date hasn’t passed.
Conclusion
In short, yes, you can eat eggs that expired a month ago, but it depends on how they’ve been stored and their condition when you check them. If your eggs have been kept in the fridge and pass the float, sniff, and visual tests, they are likely still good to eat. However, be aware of the risks of foodborne illness and spoilage, and always cook eggs thoroughly to reduce the chances of getting sick.
If you’re unsure or the eggs show any signs of being spoiled, it’s better to throw them out than risk your health. Proper storage and regular checks can help you make the most out of your eggs while minimizing waste.
