Problems with lead exposure in the U.S. are far more pervasive and far closer to home than many might think–namely, in the food we eat (leaching from food packaging containers), in cosmetics like lipstick, and lead in bottled water bought at the supermarket.  But the other problem with lead–why it still exists in our food, cosmetics and water–is a political one.  A group of organizations has recently sent a formal petition to the Food and Drug Administration (FDA) urging the agency to revise its outdated standards for lead in food to better protect the public.
