The Food and Drug Administration has issued an advisory for six brands of ground cinnamon due to lead contamination. The brands are La Fiesta, Marcum, MK, Swad, Supreme Tradition and Eli Chilar. The FDA said the lead levels in these products are much lower than those found in cinnamon apple sauce pouches that were recalled last fall. Long-term lead exposure can pose significant health risks, especially for children. It has been linked to slower development, brain and nervous system damage, behavioral and learning problems, and hearing and speech problems.
