Will I die if I eat eggs one or two days after "Best before"?

As someone already mentioned. "Best before" isn't "Used by".

Yet as someone else mentioned, put the eggs in a bowl of water and if they float, then discard it.

Unfortunately not all stores give a use by date. Only a use Best before date, which is not the same thing.

'Best Before' is not a 'Used By' Date...educate yourself....and use your sense of smell.

Put the eggs in a bowl of water or deep pot. if they float they are bad. Sink ok to eat.

Not if properly stored

Not if their cold & Smell them 1st

Not unless they came from a Voodoo Chicken.
