A common spice sold at discount retailers across the U.S. is contaminated with high levels of lead, federal authorities said this week.

Ground cinnamon sold by stores including Dollar Tree and Family Dollar contains elevated levels of lead and prolonged exposure to these products may be unsafe, the Food and Drug Administration said. The products should be thrown out and the manufacturers are being urged to voluntarily recall the products.

Testing by the FDA found the products contained elevated levels of lead that could, with long-term exposure, could impact health, especially in children. No illnesses and other health issues have been reported in connection with the new ground cinnamon alert, the FDA said.

The testing followed a recall in late 2023 of cinnamon apple puree and applesauce products due to elevated levels of cinnamon in those products and reports they sickened almost 500 children. After that discovery, FDA launched a “targeted survey” of cinnamon products sold in discounted stores.
