The Food and Drug Administration (FDA) issued a new alert on Thursday regarding the discovery of lead contamination in another cinnamon product sold in the U.S. The ground cinnamon, sold under the brand El Servidor and distributed by an Elmhurst, New York company, was found to contain lead levels of 20 parts per million (ppm).

The FDA’s alert adds El Servidor cinnamon to a growing list of contaminated products. The United Nations’ Food and Agriculture Organization has a proposed safety standard of 2.5 ppm for lead in bark spices like cinnamon, significantly lower than the levels found in El Servidor’s product. The FDA has asked the distributor to voluntarily recall the product.

Earlier this year, the FDA warned about lead in cinnamon sold at Dollar Tree and Family Dollar stores, with lead levels ranging from 2.03 to 3.4 ppm. Another recall involved WanaBana apple cinnamon fruit puree, which had a sample containing 5,110 ppm of lead. The latest contaminated cinnamon was sold at a supermarket in New York City, though it is unclear if it was distributed more widely.

Leigh Frame, director of integrative medicine at George Washington University School of Medicine and Health Sciences, called the recall “alarming.” She emphasized that the current system reacts to contamination only after people get sick, which is often too late. Frame advocates for proactive testing of food products to prevent exposure to dangerous contaminants.

The FDA has reported no illnesses related to the contaminated cinnamon but advised consumers to stop using the product and dispose of it. Lead is particularly toxic to children, potentially causing long-term neurological and developmental problems such as learning disabilities and lowered IQ.

While Frame does not recommend completely cutting out cinnamon, she advises limiting exposure, especially for young children. “If you have cinnamon oatmeal every morning, maybe switch to a different variety for a while until we figure things out, just to reduce the exposure,” she suggested.
