We reported 23 cases of lead poisoning due to industrial cider being contaminated during its fabrication, this being caused by the detergents used to clean the piping. Microscopic examination of the stippled erythrocyte is not effective. On the other hand the elevation of protoporphyrines erythrocyte remains constant, and this is the most honest, long standing sign of lead poisoning. There is certainly the cumulative effect of toxication but it is the acute increase by ingestion above a certain limit (between 3 and 10 mg of lead daily according to the individual) wich provokes clinical signs and symptoms.
