If you crack an egg and the membrane is intact it OK to eat it?

No, an egg with a broken membrane should not be eaten.

When the membrane of an egg is broken, it can allow bacteria to enter the egg and contaminate it. This can make the egg unsafe to eat and could cause food poisoning.

Additionally, a broken membrane can also cause the egg to leak and lose its shape. This can make it difficult to cook and may also affect the taste of the egg.

Therefore, it is always best to discard an egg if the membrane is broken.
