Is the lead content of preserved eggs really high? Can I eat two a day?

Changed eggs are commonly known as preserved eggs and preserved eggs. The traditional formula contains lead oxide (yellow lead powder), so the lead content is really high. Because lead will accumulate in the body and cannot be discharged after eating one for two days, it is best not to eat, especially for children, and it is even more impossible to eat. It is safer to eat preserved eggs with lead-free formula now. Eating two eggs a day is no problem.
