Summary from FDA website:
"Protecting one of our most vulnerable populations, babies and young children, is among the U.S. Food and Drug Administration’s highest priorities. Today, we’re announcing a new action plan, Closer to Zero, that sets forth our approach to reducing exposure to toxic elements in foods commonly eaten by babies and young children to the lowest possible levels. Although the FDA’s testing shows that children are not at an immediate health risk from exposure to toxic elements at the levels found in foods, we are starting the plan’s work immediately, with both short- and long-term goals for achieving continued improvements in reducing levels of toxic elements in these foods over time.
We recognize that Americans want zero toxic elements in the foods eaten by their babies and young children. In reality, because these elements occur in our air, water and soil, there are limits to how low these levels can be. The FDA’s goal, therefore, is to reduce the levels of arsenic, lead, cadmium and mercury in these foods to the greatest extent possible. We are also sensitive to the fact that requiring levels that are not currently feasible could result in significant reductions in the availability of nutritious, affordable foods that many families rely on for their children. Our plan, therefore, outlines a multi-phase, science-based, iterative approach to achieving our goal of getting levels of toxic elements in foods closer to zero over time."
