A new congressional report has found some baby foods have “dangerous levels of toxic heavy metals,” including arsenic, mercury and lead. The House Oversight committee panel found the metals in rice cereals, juices, sweet potato purée and other products made by Gerber, Nurture, Hain Celestial Group and Beech-Nut Nutrition. Some of the products are branded under the names Happy Family Organics and Earth’s Best Organic. Campbell Soup, Walmart and Sprout Foods declined to cooperate in the investigation. The FDA is reviewing the report’s findings, as the congressional committee is urging stricter standards on baby food.
