How long can you leave hard boiled eggs out unrefrigerated until they spoil? I boiled mine 2 days ago, let them cool when they were done. The two I ate were perfectly boiled, not a spot of green, (my recipe, eggs submerged in cold salted water, bring to a hard boil for 5 minutes, turn off heat for five minutes then set them out to cool.) Prob is, it's been two days since I've done that and apart from the smell test I'm wondering how long they can stay out without spoiling since eggs are the kind of things that stay out for weeks not being refrigerated when laid by chickens. Thoughts? Facts? Anecdotes?
Officially, two hours, based on CDC one-size fits all food safety recommendations:
Unofficially, we always left our boiled Easter eggs out all day and never got sick.
I would not personally eat any boiled egg that sat out for 2 days. I would eat a fresh, non-conventional egg (that is, fresh from the hen) that sat out, after cooking it. These eggs have a protective cuticle intact. After all, if such fresh eggs spoiled that quickly, chicks would never develop. (Yes, I know the eggs we eat are usually unfertilized.)
Boiling might temporarily sterilize the egg, but the shell may not really prevent bacteria from entering the egg. Egg shells are permeable, and I wouldn't count on the cuticle surviving boiling intact.
I don't think you should eat them. The smell test is not reliable. If it was, no one would get food poisoning.
If they're still shelled, you can probably eat them. Oxygen is what encourages bacterial growth, among other things, and when they're contained within their shells they're still sealed off from air. Make sure there are no cracks in the shell. Trust me, if they're bad, you'll be able to smell them.
Never eat a peeled hard-boiled egg that's been left out for longer than a couple hours. Bad ju-ju!
Edit: Then I'll retract my answer.
I was told once by someone with extensive outdoor and backcountry experience that she and others she knows frequently take them on trips and eat them up to three/four days unrefrigerated, assuming that the temperature is moderate.
I've only eaten them as long as two days out because well, they're just so damn tasty.
I have left my eggs out for over 2-3 days sitting in a bowl and I haven't gotten sick knock on wood So I don't see what harm could come from it. No one has gotten sick in my family from doing that. Its like when your camping you keep them out like in a pack or bag and eat them and no one has been reported dead from left out hard boiled eggs.
Americans are really scaredy about eggs!
First, I should say that I'm American but not very, har! Anyway, I grew up on a ranch and believe me, when you're pulling in 30+ eggs a day, it's not like you can sell them easily or give them away easily (living in the Ozarks meant I'd not see non-family members for months at a time) when everybody has hens laying. We ate A LOT (certainly daily, several family members and because we grew and prepared all of our food, that meant it went into cooking, too).
Point to that is: when they come out of the hen, they're HOT (body temp). You can store them on the counter (room temp) for over a week -- again, raw. You can store them refrigerated (again, raw) over a month and not blink.
You cooked yours, though. For Easter or just because we were boiling a mess, we'd not bother about them as long as it wasn't full summer for over a week (again, cooked). I wouldn't go too far past that since your eggs probably didn't just come out of a hen's rear but you're good to go for a week! And...when I say full-summer, I mean near 38C/100F without A/C. If you're in air conditioning, you're grand.
