How to Tell If Eggs Are Rotten

Step 1: Fill bowl
Do the float test: put the egg in a deep bowl of water. If it sinks straight to the bottom, it's fresh. If it floats, it means it's old, but may still be safe to eat. Proceed to the crack test.

Step 2: Put egg in bowl
Crack a floater into a bowl and give it a sniff: if it gives off an unpleasant odor, throw it out.

Step 3: Watch the egg
No odor? Examine the egg white: a pink or iridescent appearance means it's spoiled. Don't worry about red spots -- they represent blood vessel ruptures that occurred at the time of ovulation and have nothing to do with safety or freshness.

Tip
A cloudy egg white means the egg is very fresh; a clear egg white means the egg is aging.

Step 4: Crack egg
Disregard the color of the yolk -- it varies in accordance with the hen's diet. And a green ring on a hard-cooked yolk simply means you overcooked it.

Did You Know?
When a hard-boiled egg is difficult to peel, it means it's very fresh.

I bought pasture raised eggs for the first time and when I cracked it the egg white was cloudy then I started searching YouTube till I came across your video, thanks 🙏

Nice to see someone realise that a floating egg is NOT necessarily bad.
The better way to think of it is that an egg is definitely FRESH if it SINKS.

'crack a floater into a bowl and give it a sniff'
Fuckin' LOL!

[samuellourenco]

The buoyancy test is far more sensitive than the sniff test. It catches a lot of "undecided" eggs too (those that do not sink as fast).

water float test is not accurate. you can put it under light and check if there's any black spots.

you can just shake the egg, if it is clearly sloshing about, it's old or spoilt, if it doesn't slosh, it is ok to eat.
The older an egg gets, the more air builds up inside it

[dorispeck]

We forgot boiled eggs in a pot with water in it and they have been there for like 3-5 days and we noticed it and tossed it in the trash and it for real smells like human feces right now in our house even after throwing them away

The egg will still sink if it's rotten.

[odp]

Simply shake it and if the inside is shaken it's already rotten

@REYMEXICANO4L A floater= shit that floats in the toilet bowl

How to tell if an egg is rotten: Eat it. If you get food poison, it was rotten. If it doesn't tast good, it may be rotten or maybe you just don't like eggs.

I wanted to know if there's a way to tell if an egg is rotten before cracking it up...that way, you can return it to the store and get a fresh one, but if you crack it first, you lose evidence. How do you do this?

why is my YOLK WHITE in my hard boiled egg? 1 out of 9

[jhlords]

i got a rotten boild egg that the yok was green and there were some yellow parts nasy i put it in the bin asap

[okxyjazmsp]

i was so worried about the eggs cause they were a couple of days old and i smelt them, they smelt fine i checked the egg whites they looked fine but i saw these white floaties inside my egg, is that normal?

[TheRobinRedbreast]

This is a good video but it is a bit misleading. If the egg floats throw it away. Don't play guessing games with your life. If it floats it is bad. PERIOD.

[anniehall]

Can you show what a rotten one would do in water too
