Can red eggs be eaten?

If it is an egg dyed with mercuric chloride, don't eat it. It is a custom to dye eggs red with mercuric chloride as a symbol of celebration. Mercuric chloride, also known as mercuric chloride, is a disinfectant for external use and cannot be taken orally because it contains toxic mercury.
