Yes eating lead can kill you and in a short amount of time as well.
If you ingest enough lead over a few days then you can be lead poisoned and die within a few days or even the day after ingesting the lead.
If you have lead in your house such as lead paint you need to remove any lead paint flakes so that a child does not eat the lead.
If your child or toddler ingests any lead you need to take them to urgent care or the emergency room for treatment.
Because the ingestion of lead paint and lead can cause death in toddlers and children in a short amount of time.
If you do have lead paint in your house that is flaking you should if possible get it removed.
Lead should never be ingested because your body does not need any lead and it's poison to ingest.
