What causes blood spots in eggs?

Blood spots are also called meat spots. Occasionally found on an egg yolk. Contrary to popular opinion, these tiny spots do not indicate a fertilized egg. Rather, they are caused by the rupture of a blood vessel on the yolk surface during formation of the egg or by a similar accident in the wall of the oviduct. Less than 1% of all eggs produced have blood spots.

Mass candling methods reveal most eggs with blood spots and those eggs are removed but, even with electronic spotters, it is impossible to catch all of them. As an egg ages, the yolk takes up water from the albumen to dilute the blood spot so, in actuality, a blood spot indicates that the egg is fresh. Both chemically and nutritionally, these eggs are fit to eat. The spot can be removed with the tip of a knife, if you wish.

Blood spots are more commonly found in brown eggs. The reason is two-fold. Firstly, the genetics of brown birds predisposes them to lay more eggs with blood spots in them. Secondly, during the candling procedure, the brown shell of the egg appears to have a red tint to it, which makes the task of looking for a red spot behind it extremely difficult.

What are the tiny red spots inside a chicken's egg white?

These are called blood spots. Blood spots are the result of broken capillaries in the reproductive system. When a capillary ruptures, a drop of blood leaks out and becomes part of the egg. The presence of a blood spot does not mean the egg is fertile or that an embryo is beginning to form. Egg processors try to identify and remove all eggs containing blood spots before eggs go into the carton. Occasionally one is missed, but if the blood spot is small, it can be removed and the egg used. They are harmless and do not mean the egg is inedible. Small ones disappear when you are cooking the egg. Some people pick them out with a spoon before cooking.

Why do brown eggs have more blood spots than white eggs?

Brown eggs are more difficult to candle...candling is done on the production line and the brown color on the outside of the egg makes it more difficult to spot the defects inside. White eggs are more popular with consumers for home use and they are easier to candle. The food industry prefers brown eggs as the shell color makes it easy to spot errant bits of shell when used in recipes, blood spots are ignored by most chefs as they disappear when cooked and make no difference in the quality of the food.
