One sample of cinnamon used as an ingredient in the recalled WanaBana apple cinnamon fruit puree contained lead levels that were more than 2,000 times higher than proposed safety limits, the Food and Drug Administration said Monday.

The FDA tested samples of the spice as it investigates at least 65 cases of lead poisoning in children in the U.S. that are linked to contaminated cinnamon applesauce pouches.

At the end of October, WanaBana USA announced a recall of its apple cinnamon fruit puree pouches because of elevated lead levels. In November, the recall was expanded to include two other products made by the company: the supermarket brands Schnucks applesauce pouches with cinnamon and Weis cinnamon applesauce.
