Eggs are a kitchen staple—versatile, nutritious, and packed with protein. But what happens when you notice your egg carton has passed its expiration date? Can you still use them, or is it time to toss them out?
This is a common household dilemma, often leading to debates over food safety, expiration dates, and storage methods. Some people insist that expired eggs should never be eaten, while others claim they are safe weeks beyond the date.
So, what’s the truth? Let’s crack open the facts and settle this debate once and for all.
Understanding Egg Expiration Dates
One of the biggest sources of confusion is the expiration date printed on egg cartons. Many consumers assume that once this date has passed, the eggs are automatically bad or unsafe to eat. But that’s not entirely accurate.
Egg cartons typically have one of the following labels:
✔️ Sell-By Date – A guideline for retailers, indicating how long eggs should be displayed for sale. Eggs are still safe to eat beyond this date if stored properly.
✔️ Expiration Date (EXP) – This is the suggested last date for using the eggs, but not a strict safety deadline. Many eggs remain fresh for weeks past this date.
✔️ Pack Date (Julian Date) – A three-digit code that represents the day of the year the eggs were packed. For example, “001” means January 1st, while “365” means December 31st. Eggs can often remain good for four to five weeks after this date.
So, does an expired date automatically mean bad eggs? Not necessarily. The key lies in how eggs are stored and tested for freshness.

How to Determine If Eggs Are Still Safe to Eat
Instead of relying solely on expiration dates, use simple and reliable tests to determine egg freshness.
1. The Float Test (Most Popular Method)
The float test is an easy and effective way to check an egg’s freshness. Here’s how:
1️⃣ Fill a bowl with cold water.
2️⃣ Gently place the egg into the water.
3️⃣ Observe the results:
- Fresh eggs sink and lay flat on the bottom.
- Slightly older eggs stand upright but remain at the bottom.
- Spoiled eggs float to the top and should be discarded.
Why does this work? Over time, air enters the egg through its porous shell, causing it to become more buoyant. Floating means there’s too much air inside, signaling that the egg is no longer fresh.
2. The Sniff Test
Crack the egg open and give it a quick sniff. If you notice a strong sulfur-like or rotten smell, the egg is bad and should not be eaten. Fresh eggs have a mild or neutral scent.
3. The Visual Test
Look at the egg’s:
✔️ Egg white: A fresh egg has a thick, slightly cloudy egg white. A watery or runny white suggests it’s older but still safe.
✔️ Yolk: A bright yellow or orange yolk is a good sign, while a flattened yolk can indicate age.
✔️ Unusual discoloration: If you see dark spots, mold, or pinkish hues, throw the egg away immediately.
The Science Behind Egg Freshness
What makes eggs go bad over time? The answer lies in their natural structure and storage conditions.
- Eggshells are porous, meaning air and moisture can pass through over time. This process accelerates if eggs are not stored properly.
- Carbon dioxide and moisture loss cause eggs to become less dense, affecting their texture and taste.
- Refrigeration slows bacterial growth, keeping eggs fresh for much longer.
If eggs are kept in the refrigerator, they can stay safe to eat for up to 4-5 weeks after the pack date. However, eggs stored at room temperature spoil much faster.
Common Misconceptions About Expired Eggs
❌ “Eggs become unsafe the moment they expire.”
✅ Not true! If stored correctly, eggs remain good for weeks past their expiration date.
❌ “If an egg has a runny white, it’s bad.”
✅ Not necessarily. A runny egg white means the egg is older, but it can still be safe to eat if there are no bad smells or discoloration.
❌ “You can’t eat raw eggs if they’re past the expiration date.”
✅ While fresh eggs are best for raw consumption, properly stored eggs past their expiration date can still be used for baking and cooking as long as they pass the freshness tests.

Health Risks of Eating Spoiled Eggs
While most expired eggs are still safe, consuming truly rotten eggs can pose health risks. Spoiled eggs may contain bacteria like Salmonella, which can cause food poisoning.
⚠️ Symptoms of food poisoning from bad eggs include:
- Stomach cramps
- Nausea and vomiting
- Diarrhea
- Fever and chills
If you suspect an egg is spoiled, it’s better to be safe than sorry—throw it out.
Practical Tips for Storing Eggs Safely
To extend the shelf life of eggs and keep them fresh longer, follow these storage tips:
✔️ Store eggs in the refrigerator – Keep them at or below 40°F (4°C) to slow bacteria growth.
✔️ Keep them in their original carton – This prevents moisture loss and protects eggs from absorbing strong odors.
✔️ Avoid storing eggs on the fridge door – The temperature fluctuates every time the door is opened. Instead, keep them on a middle shelf where the temperature is more stable.
✔️ Wash eggs only before using them – Washing eggs can remove their protective coating, making them more vulnerable to contamination.
✔️ Use older eggs for baking and cooking – If your eggs are past their expiration date but still pass the float and sniff tests, use them for scrambled eggs, baking, or boiling instead of eating them raw.
Resolving Disagreements Over Expired Eggs
If you and your partner or family members disagree about eating expired eggs, here’s how to handle it:
✔️ Communicate openly – Discuss concerns and agree on a testing method (like the float test) before making a decision.
✔️ Compromise – If one person is uncomfortable with using older eggs, use them for non-direct consumption (baking, frying at high heat, etc.).
✔️ Rely on expert recommendations – Food safety experts emphasize sensory tests over printed dates.
Final Thoughts: Are Expired Eggs Safe to Eat?
Egg expiration dates can be misleading, but understanding how to check for freshness can prevent unnecessary waste. While eggs do not instantly spoil after the expiration date, proper storage and freshness tests are essential for safe consumption.
Next time you find yourself debating whether to eat or toss expired eggs, remember: a simple float or sniff test is all you need to make the right decision!
20+ Things That Could Even Puzzle Sherlock Holmes
Once in a while, we come across things in our household that we can’t identify. If this happens to you, just know that you can ask the experts on Reddit. Here, people from all around the world share their knowledge and help figure out the purpose behind some really mysterious things.
Now I’ve Seen Everything can now say we haven’t really seen everything and here are some mysteries the internet managed to solve!
1. “Part with spokes rotates, spokes (of different diameters) match up to hole in the opposite side of the tool. Sharpie marker for size.”
Answer: It is for punching holes in leather or similar things. Like, for a belt.
2. “This little plastic basket/holder inside the far corner of a trolley — I asked the supermarket staff, they had no idea.”
Answer: It’s a bitz box (a place for small items, like pens, batteries, etc.).
3. “I know it’s a chair, but what’s with the extended arms?”
Answer: It looks like a plantation/planter chair. You’d put your sore, swollen legs up on the arms after sitting on a horse all day, like a pregnant woman with her legs up in the same fashion. This is why the back is so sloped as well. If you sat up straight it wouldn’t be comfortable to put your legs up like that, but in a reclined position, it’s good for blood flow and airflow.
4. “Small, light blue, rubber capsule with a tear-off end.”
Answer: It’s a cosmetics serum capsule.
5. “My coworker saw this toilet in the women’s restroom at the Huntsville Space Center. Why is it shaped this way?”
Answer: It is a woman’s urinal. It encourages women to urinate from a standing position without the need to sit on a shared seat.
6. “I’m waiting for the bank to open and they have this card facing the street. What is it used for?”
Answer: It’s definitely a safety signal. We switch ours quarterly and it’s to let other employees know that it is all clear to open. Typically we had 2 employees “open” the branch while the rest waited in the parking lot or across the street for “all clear.” The openers go in, turn off the alarm, search the building, and check everything, then set the signal.
7. “In the middle of the wall in my 1906 house”
Answer: It’s a capped-off gas line from when they used gaslighting.
8. “Found this in Guam in shallow water, 3 meters in diameter. Never seen anything like it.”
Answer: This is absolutely a rocket part.
9. “Opposite of hole-y: what is this not-really-spiky kitchen spoon for?”
Answer: It’s a spaghetti server.
10. “What is the S-shaped metal ornament on this house?”
Answer: It’s an anchor plate or wall washer. It’s meant to keep masonry in place and made aesthetically pleasing because they’re visible. There is a bolt going on the other side, in the center, holding the bricks in place.
11. “What is this piece of seemingly old tech? Found in a pile at a university.”
Answer: That’s a very old wearable computer.
12. “My house (built in the mid ’70s) has one of these in almost every room.”
Answer: The 3-prong ones were for TV and FM antennas, and the center one was for an antenna rotator to get better reception.
13. “This is an on-gate blocking road access to some cell towers. Why so many locks and how would someone even open it?”
Answer: You can open the gate by unlocking only one padlock. The way it’s designed means that multiple people can use the gate, and if one person loses their keys, only their padlock needs to be replaced. As opposed to one padlock with many keys, you’d need to give tons of people the new key.
14. “What are these shredded balls on my property?”
Answer: Juniper-hawthorn rust — it’s a fungal disease. It starts as a gall then the tentacles appear around spring or after rain. It probably won’t kill this tree but it can seriously mess up secondary host apple trees. The only way to get rid of it is to prune then burn the removed branches. Don’t forget to disinfect your tools after.
15. “A cast iron circle with raised edges and a zero”
Answer: I think it’s a support for an old waffle maker.
16. “I found this while cleaning out an old cedar closet. Had a bendy spring in the middle. Looks like it hangs on a door?”
Answer: I think it’s a vintage hat display stand. If you Google it, there are a lot that have the springy bit and the pull cord (it probably lets you pull the hat down and to the sides to examine it rather than touching the hat itself). Yours seems to be held by sliding onto a table edge rather than sitting on the table itself. So you’re holding it sideways.
17. “What is this stuff growing out of the nail holes in my ceiling?”
Answer: That’s termite frass. You’ve got bad termites and you’ll want to deal with it ASAP.
18. “I just bought a house and this weird triangle holder thing is by my kitchen sink. What is it?”
Answer: It’s a dishtowel holder. Take the corner of your dishtowel and put it to the back of the triangle, then pull down on the towel and it’s held in place.
19. “Found this buried in the garden, very tough glass.”
Answer: My father repaired TVs for decades. I can confirm this one is the glass back.
20. “I bought these at a thrift store. Thought it was a bar spoon but I’m not certain.”
/
Answer: They’re ice cream spoons.
21. “I found this in our kitchen drawer when I moved in, none of my roommates have any idea. What is this thing?”
Answer: It’s a part of a tea infuser.
22. “Found these when clearing out my dad’s wardrobe. Any idea what you’d hang on them?”
23. “It is made of steel/iron and is heavier than it looks. We’re not sure if it’s a tool or some type of kitchenware.”
