NOTE: The statement below was extracted from an FDA recall.
High Levels of Lead: Lead is very toxic and dangerous to humans, especially children, women of childbearing age, pregnant women and their unborn children. Although people with lead in their blood often do not exhibit the symptoms of lead toxicity, such symptoms include the following: stomach aches, colic, nausea, vomiting, abnormal irritability, and insomnia. Lead can also permanently damage the central nervous system, resulting in learning difficulties in school children as well as cause other long-term health problems.
