A new study indicates that chocolate can be contaminated with extremely high quantities of lead.
The problem with lead in chocolate has been known before now; it had been assumed that cocoa plants were tainted by leaded gasoline. However, a team of researchers has found that lead levels in processed chocolate are 60 times higher than could be accounted for by this.
It is currently unknown whether the additional contamination is coming from the shipping or the manufacturing process.
Elevated blood lead levels in children can produce learning disabilities, including damage to a child's ability to think, plan, organize and memorize.
