Toxic elements like lead, arsenic, mercury, and cadmium in food are not a new problem. But when they show up in pureed vegetables and other foods intended for babies, alarm bells go off. That’s what happened in recent months following a bombshell congressional report that found neurotoxic metals in baby food from multiple manufacturers. In this episode of Stereo Chemistry, host Kerri Jansen and C&EN reporter Britt Erickson explore the fallout from that report and renewed efforts by baby food manufacturers, regulators, advocacy groups, and agricultural scientists to rein in the problem.
