TIL: You can easily check eggs for being bad or fresh

My egg packages here in Sweden have that information printed on them.

But the version where the egg floats they don’t say to toss it out, but rather crack it open, look, smell. Might still be good.

Exactly, the egg floating doesn't mean that it's not edible anymore, just that it's old.
- Yes, I'm sick of seeing this infographic and ones like it as it encourages waste
Exactly. If an egg has gone bad, you can't really miss it.

Also why it's good to always quickly check eggs before adding them to a mix.
- Assuming you have a sense of smell. Anosmia affects about 3% of people - probably more since Covid.
- I made the mistake of not checking once, as I was cracking eggs into a running mixer. It was awful, I'll never forget again.

Nice try 4chan, last time I microwaved an Iphone.

Oh no, you created mustard gas
Don't eat spoiled eggs.

I had a coworker who did. She had to go to the emergency room and missed work for a month.

I think I dunno. That was her story. She could have went to Cancun or backpacked in Europe and made up the story.
- What I learn from this is that if I eat spoiled eggs, I have a 2/3 chance of ending up in Cancun or backpacking across Europe. Brb

Why does the tosser egg have some sort of donut shaped cereal in the bowl?

Clearly they mean: toss the egg in a bowl of Frootloops!
- That makes sense, breakfast food + breakfast food = breakfast.
It’s part of a complete breakfast.
And what is the picture in the background? It sort of looks like breasts.

I live in a country where they don't boil and bleach the duck placenta off of the egg so you can just sort of keep them on the floor outside of the refrigerator for days and it doesn't matter it's fine

for how long?
- Until you eat them
- I'd say for a few weeks, at least for me i keep eggs on the counter and have never had spoiled eggs
boil and bleach the duck placenta off of the egg

What on earth.

Is this a non-US thing? I’ve never heard of this practice and I worked for a farmer that raised chickens and sold eggs.
- An industrialized system to promote waste. None of the smaller farms in my area (Eastern Ont Canada) wash their eggs but the ones that get sold to stores must.
- Not boiled but "washed" probably with bleach.
  
  Eggs are porous. Birds leave a coating on them that blocks the pores and prevents bacteria getting in but washing the eggs removes that protective coating.
  
  Pretty sure you do this in the US but not every country does.

Remember, if the thick cloud emitted by the egg only drifts upwards, it's probably no good.

No, this graphic really is solid advice for people to know, but damn if it could have been designed with a little more forethought. Imagine, for instance, if the reader is yellow/blue colorblind. They could make a guess at what's happening, but they may not quite be sure. Arrows are doing 99% of the lifting, here.

I think it's if it produces both a thick gas cloud and Fruitloops. If it's only one of those, it may still be good.

Why is this though? What’s the science for making old eggs float?

The older an egg gets the more experienced it gets with swimming. I once had an egg that was so old, it could do 4 laps in an Olympic swimming pool in under a minute

Unfortunately by that zime it had already gone bad. Started smoking, got into trouble with the law, that sorta stuff. Must be because of that satanic heavy metal music
The egg start to decompose and produces gas. Some of that gas escapes through the shell, so the egg's mass decreases, which causes the density of the egg vs water to drop.

As an egg gets older it starts to break down, so it's density becomes less. Eventually it's density will be less than the water so it'll begin to float.

But which stage is best for hard boiling?

As close as you can get to "eat soon". It'll have a decent air pocket developed and the membrane adhering to the shell will be weaker.

Advice: Don’t trust infographics with zero source reporting for things as important as food safety.

This doesn't tell you if it's good or bad. Just tells you if it's new or old. Older eggs have more air in them.

If it has so much it floats, you have to throw it away.
- I regularly cook eggs that float on water before boiling. It's still good. Don't waste food.
- The difference between sinks and floats is a pretty small amount of air. Now if the egg truly does go sideways then there is probably an issue because the air sack has broken. But floating itself doesn't say anything about the safety of the egg.

You've obviously never experienced 4

This is extra important if you're eating eggs you got from A Guy instead of like a supermarket.

I get my eggs from B Guy
I get my eggs from my E guy. He handles all my eggplant needs too.

Gotta eat me some chicken menstruations. Mmm mmm!

Menses.

Also, that's some really bad biology there.

The closest comparison to human cycles could be ovulation, not menstruation. Hell, it would be closer to childbirth than menstruation.

Also, the sounds hens make before, during, and after laying are... impressive. Definitely closer to childbirth in that regard.
They used to have the six piece on the dollar menu. But that’s capitalism for you. 🤷‍♀️
