Is it safe to eat an egg with a blood spot?

An egg with a blood spot is safe to eat. Blood spots are merely caused by a ruptured blood vessel during egg formation. They account for less than 1% of eggs and are usually sorted out from the rest. However, since it’s harder to see the blood spots in brown eggs, some can slip through among the others. If you like, you can remove the blood with the tip of a clean knife before cooking the egg.
