The U.S. Food and Drug Administration said cinnamon sold by stores including the Dollar Tree and Family Dollar contains lead at levels that could be unsafe for people, particularly children, with prolonged exposure to the spice. The agency urged suppliers to recall the products voluntarily.
Cinnamon products included in the agency’s safety alert include the La Fiesta brand sold by La Superior and SuperMercados; Marcum brand sold by Save A Lot stores; MK brands sold by SF Supermarket; Swad brand sold by Patel Brothers; El Chilar brand sold by La Joya Morelense; and Supreme Tradition brand sold by Dollar Tree and Family Dollar stores.
