Several U.S. discount retailers recalled packages of ground cinnamon after federal health officials warned that they were contaminated with high levels of lead. The U.S. Food and Drug Administration issued a safety alert for six brands of cinnamon, including those sold at Dollar Tree and Family Dollar stores. The move followed massive recalls last fall of WanaBana and other brands of cinnamon applesauce pouches linked to nearly 500 reports of lead poisoning in young children in 44 states. The FDA tested retail samples of spices to determine whether other products were contaminated. The new recalls are raising questions about the safety of cinnamon, a popular spice found in many American kitchens. Here's what you should know: Which brands of cinnamon have been recalled? Recalls have been issued for Marcum and Supreme Tradition brand ground cinnamon sold at Dollar Tree, Family Dollar and Save A Lot stores nationwide.
