Egg coding inks are food-grade and non-toxic, meaning they are safe if a tiny amount is consumed and they will not contaminate the egg inside. They are not “edible” in the sense of being a food ingredient.
Food-grade ink stays on the shell surface and does not penetrate to the egg white or yolk. Even after boiling or refrigeration the mark remains legible and does not bleed inward.
Best practice is still to avoid eating the printed shell, but consumers and inspectors can be confident the code is safe and compliant.
