You’re standing there with the fridge door wide open, squinting at a carton of eggs that’s been sitting behind the oat milk for... well, you aren't exactly sure how long. We’ve all been there. You want an omelet, but you don’t want food poisoning. The date on the carton says they expired three days ago, but they look fine. They don't smell. So, do you risk it?
Most people toss them way too early. Honestly, it’s a massive waste of money. If you’re wondering how long can raw eggs last in fridge, the answer is probably a lot longer than the "sell-by" date suggests. We’re talking weeks, not days. But there is a massive difference between a grocery store egg and something you grabbed from a local farm, and if you handle them wrong, you’re basically inviting bacteria to dinner.
The Real Timeline for Freshness
Let’s get the basics out of the way first. According to the USDA and the American Egg Board, shell eggs are typically good for 3 to 5 weeks from the day you put them in the refrigerator. That’s a huge window. Even if that "sell-by" date has come and gone, the eggs inside are usually perfectly safe to eat for several more weeks.
Why the discrepancy? The date on the carton isn’t a safety date. It’s a quality date. Over time, the white gets thinner and the yolk gets flatter. It might not make a "tall" fried egg, but it isn't going to kill you. However, once you crack that egg, the clock starts ticking much faster. If you’ve got raw egg whites or yolks sitting in a bowl, you’ve only got about 2 to 4 days before they need to go in the trash. Hard-boiled eggs? Surprisingly, they expire faster than raw ones because the boiling process removes a protective waxy coating. You get one week with those, tops.
Temperature Stability is Everything
Here is where most people mess up. You know that cute little egg rack built into the door of your refrigerator? Stop using it. Seriously.

The door is the warmest part of the fridge. Every time you open it to grab a snack, those eggs are hit with a blast of warm kitchen air. Fluctuating temperatures are the enemy. If the temperature of the egg rises and then falls, it can cause "sweating" on the shell. Moisture on a porous shell is a literal highway for Salmonella to travel from the outside of the egg to the inside.
Keep them in the original carton. It’s not just for the date; the carton protects them from picking up odors from that leftover onion or funky cheese you forgot about. Store them in the main body of the fridge, ideally toward the back where the temperature stays a steady 40°F (4°C) or slightly below.
The Famous Water Test: Fact or Fiction?
You’ve probably seen the "float test" on TikTok or heard about it from your grandmother. You drop an egg in a glass of water. If it sinks, it’s fresh. If it stands on one end, it’s getting old. If it floats, it’s "rotten."
It’s actually a pretty decent science experiment, but it’s not a perfect safety test. Eggs have an air cell at the large end. As the egg ages, moisture escapes through the pores of the shell and is replaced by air. The bigger the air pocket, the more the egg floats. So, a floating egg is definitely old, but it isn't necessarily spoiled.

Spoilage is caused by bacteria. An egg can be old (and floaty) but still be bacteria-free. Conversely, a sinking egg could technically be contaminated if it was handled poorly. Use the float test to check for quality—like if you need a super fresh egg for poaching—but use your nose to check for safety.
What About Farm Fresh vs. Store Bought?
This is where things get kinda weird. In the United States, commercial eggs are washed. This removes dirt and potential Salmonella from the shell, but it also strips away the "bloom." The bloom is a natural, protective layer that seals the pores. Because this is gone, American eggs must be refrigerated.
In many European countries, they don't wash the eggs. They keep the bloom intact, which is why you’ll see eggs sitting on room-temperature shelves in London or Paris. If you get eggs from a neighbor’s coop and they haven't been washed, they can stay on your counter for a couple of weeks. But once you wash them or once they’ve been refrigerated, you can’t go back.
Spotting a Bad Egg Without a Lab
If you’re still nervous about how long can raw eggs last in fridge, just use your senses. It’s actually pretty hard to miss a truly rotten egg.

- The Sniff Test: This is the gold standard. A spoiled egg will have a distinct, pungent sulfur smell the second you crack it. If it smells like nothing, it’s fine.
- Visual Check: Look at the shell. Is it slimy? Is there a powdery residue? Sliminess indicates bacteria; powder usually means mold. Inside, if the white is pink, green, or iridescent, toss it immediately. That’s a sign of Pseudomonas spoilage.
- The Crack Test: If you crack an egg and the yolk is watery and the white spreads out like a puddle, it’s old. It’s still safe for baking or scrambling, but maybe don’t try to fry it sunny-side up.
The Salmonella Factor
We can't talk about egg longevity without mentioning Salmonella. It’s the big scary monster under the bed for egg lovers. According to the CDC, about 1 in every 20,000 eggs contains this bacteria. While those odds are low, they aren't zero.
The risk increases as the egg ages because the physical barriers (like the membrane) start to break down, making it easier for bacteria to reach the nutrient-rich yolk. If you are serving eggs to someone with a weakened immune system, the elderly, or small children, don't play the "how long can this last" game. Use the freshest eggs possible and cook them until the yolks are firm.
Freezing Eggs: A Pro Move
Did you buy three dozen eggs because they were on sale? You can actually freeze them. You just can’t freeze them in the shell. They will expand and explode. It's a mess.
Instead, crack them into a bowl, whisk them together, and pour them into an ice cube tray. Once frozen, pop the cubes into a freezer bag. They’ll stay good for up to a year. This is a lifesaver for bakers. Just remember to thaw them in the fridge overnight before you use them.
Actionable Steps for Maximizing Egg Life
To make sure you aren't wasting food or risking a stomach bug, follow these specific rules:
- Check the pack date: Look for a three-digit code on the carton (the Julian date). 001 is January 1st, and 365 is December 31st. This tells you exactly when they were packed, regardless of the "sell-by" date.
- Keep 'em cold: Put your eggs in the fridge as soon as you get home. Don't leave them in a hot car while you run other errands.
- The "One-at-a-Time" Rule: If you’re using older eggs for a recipe, crack them into a separate small bowl first. That way, if you do hit a "stinker," you haven't ruined the whole bowl of batter or the entire pan of carbonara.
- Cook thoroughly: If an egg is past its prime but doesn't smell, cooking it to an internal temperature of 160°F kills most pathogens.
Knowing how long can raw eggs last in fridge basically comes down to trusting the process. If you keep them in the back of the fridge, in their carton, and they pass the sniff test, you’re usually good to go for up to five weeks. Stop tossing money down the drain just because a calendar date said so. Use your eyes, your nose, and a little bit of common sense.
