Any amount of lead is toxic. There is no safe amount of lead.
In a perfect world, we would eat no lead, but the stringent regulations that it would take to require that would hurt business. And these safety regulators have discovered that hurting business and the economy can cause real measurable harm to people's quality of life over all. So they are forced to allow lead.
But do NOT be thinking "it's okay, my body can tank a little lead". It will cause harm in ANY amount you get into your body. It soaks into your bones, and will be released in your later life stages as you become weaker, increasing heart attacks and alzheimers.
