What is blood spot mean on an egg?

While it is unusual for you to find a blood spot in an egg from the store, it is not unusual to find one from an egg purchased from a local eggs farm stand. Blood spots are simply a malfunction in the oviduct of the hen. As the egg forms, it is common for small blood vessels to break releasing a tiny amount of blood which is then visible either in the yolk or the albumen of the egg. Blood spot, while unappetizing to most consumers are not bad or dangerous and will disappear when cooked. Home cooks often work hard to remove the slightest bit of blood from the egg when cooking at home but I can assure you that most restaurants don't bother to remove a small blood spot when cooking your breakfast and you would never know once the egg is cooked and served.
