Forgot to unload part of groceries and left eggs out in the car overnight.
Throw them out and replace them, or risk salmonella?
Yeah, replace.
They’re fine for several days unless it got too hot or too cold in the car. I keep fresh eggs out on the kitchen counter all the time.
If you think about it, an egg must remain fresh in the community nest until a hen gets the hint & begins to brood. So eggs can be waiting for several days until they’re brought up to temp by the hen, then their growth is activated.
I’d crack one of the eggs in a cup & smell it. If it smells neutral you’re fine. If it smells janky, then toss.
@Lulz4l1f3 Funny thing in most of the world eggs don't need to be refrigerated. In the US we require they be chemical washed removing the protective layer nature provided them, so they DO require refrigeration.
