Elevated levels of lead have been found in 12 of 36 ground cinnamon products and spice blends, according to a Consumer Reports article published Thursday.
The U.S. Food and Drug Administration does not set lead-level thresholds for spices, but three of the products exceeded a proposed cutoff set by the American Spice Trade Association, and 12 exceeded a more stringent cutoff level set by New York State.
The level of lead identified in these products is not likely to pose an immediate health risk. There are trace levels of lead and other heavy metals in many of the foods we eat.

Because of these health concerns, the FDA is actively monitoring ground cinnamon supplies and has recently alerted the public about certain products.
Last year, a major recall of apple cinnamon pouches with high lead levels led to health problems in at least 90 confirmed cases. This year, the FDA has released multiple health alerts for ground cinnamon products with elevated lead levels.
In July, several New York distributors recalled ground cinnamon products that were potentially contaminated with increased levels of lead.
The cinnamon tested in the Consumer Reports investigation included store-bought cinnamon and other cinnamon-containing spice mixtures. Again, three of these products had levels exceeding a proposed cutoff set by the American Spice Trace Association. When contacted by Consumer Reports, two of the three companies (Paras and EGN) said they would withdraw those products from the market.
Cinnamon may have a higher lead level risk because cinnamon trees grow for years before their bark is harvested, giving them more time to absorb lead in the soil.
In small amounts, lead exposure may not lead to any symptoms, but the Centers for Disease Control and Prevention notes that significant or chronic lead exposure can cause various health issues including hypertension, kidney dysfunction, or cognitive issues in adults, and central nervous system damage like seizures and developmental defects such as learning disorders or other long-term health problems in children.
Doctors say there is no known safe level of lead for children.
