Is it OK to eat overcooked hard-boiled eggs?
When you boil eggs, hydrogen sulphide – a toxic gas is released in the whites of the egg. This happens especially when you overboil the eggs. If you have noticed, overcooked eggs have a green coating on their yolk, which is a signal that you should not eat them

Yes, it is safe to eat. This green colour is caused by overcooking the egg and is due to the high amounts of sulphur and iron reacting with the surface of the yolk. Can I cook eggs in the microwave?
