Halacha Yomis - Eggs: Bloodspots OU Kosher Halacha Yomis This column is dedicated in memory of: Rav Chaim Yisroel Belsky, zt'l, Senior OU Kosher Halachic Consultant (1988-2016)

I cracked several eggs into a recipe without checking, and then noticed a bloodspot on one of the yolks. How much do I need to remove? If a fertilized egg develops to the point that a bloodspot appears on the yolk, the entire egg becomes forbidden. However, today’s commercially sold eggs can be assumed to be non-fertilized eggs. If one finds a bloodspot on a non-fertilized egg, one may simply remove the bloodspot and use the rest of the egg. However, Rav Moshe Feinstein, zt”l, (Igros Moshe Y.D. I:36) maintains that since eggs are relatively inexpensive the common custom is still to throw away the entire egg. But if it was already mixed with other eggs or food and this would be difficult, then one can simply scoop away the bloodspot. If the bloodspot itself is already mixed in, and cannot be removed, the bloodspot is batel (nullified) and the food may be eaten.
