Yep...not the most appetizing sight when you're making breakfast. Nobody likes cracking an egg and seeing anything other than a beautiful, richly colored yolk nestled in a clear egg white. But once you learn a little more about blood spots (and all the other fascinating ins and outs of eggs), you might be a little less grossed out by these rare instances.
What are blood spots in eggs?
Contrary to popular belief, blood spots are not the beginnings of a chick embryo. They're simply the remnants of a ruptured blood vessel that occured during the egg's formation. Most often, the ruptured vessel forms a tiny speck or dot of blood with a dark red, brown, or even black hue. Sometimes, larger vessels burst, and this allows blood to pool throughout the entire egg. In these cases, the egg white may have a pink or red tinge. In either case, these blood spots are a natural part of egg laying. In fact, blood spots indicate a particularly fresh egg because as they age, the spot diffuses into the white and becomes undetectable.
What causes blood spots in eggs?
The cause of a blood spot is simply a ruptured blood vessel on the yolk's surface as the egg is forming. This is a natural, benign process for both hen and egg. Instances of blood spots can increase when hens in a flock get excited by changes in lighting, changes in temperature, or simply shifting seasons. So it's okay if it feels a little bit yucky, but know that all is well.
Can I eat an egg with blood in it?
Absolutely – eating an egg that has a blood spot won't hurt you. While you may wish to remove the spot with the tip of a knife and dispose of it, there is nothing in it that's harmful for human consumption.
