Beryllium oral ingestion

Oral ingestion of beryllium has not been associated with any clinical diseases, and current studies do not suggest any risk from oral ingestions. While lung cancer is probably associated with increased beryllium exposures, the best data seems to indicate that the high exposures which occurred in the past were responsible, and suggest that cancer risk is not now a major problem. 

Highly toxic by ingestion (see Beryllium) LD50 oral (rat) 86 mg/kg. It is a confirmed carcinogen and can cause an adverse reproductive effect.
