I tuned into the California Prop 65 Warning label which is now applied to this product. Not knowing exactly why the product carried the label I contacted the company. They explained that the warning is only on 24 of their many products, which are mandated to comply with California Law which is more strict than the FDA. The reason for the warning was a low level of lead in the product.
There is no excuse for this except the one provided by the FDA. The FDA, your Food and Drug Administration, allows low levels of dangerous, heavy metals in manufactured good, personal care products, dinnerware, cookware, foods and many other items. This casual use of dangerous heavy metals like mercury, lead, arsenic and aluminum is systematically killing millions of people every year with diseases that are misdiagnosed as anything but heavy metals. There is no amount that is acceptable to the body.
