The way people get acute lead poisoning is through exposure to old paint right at home. The stereotype is of a poor child eating a paint chip in a dilapidated housing project.

In Part 2 of the re-broadcast of our series, “The Silent Epidemic”, Deirdre Kennedy reports on how one young family learned about lead poisoning the hard way.
