Duncan Hines recalled four of its cake mix flavors after the FDA found salmonella in a sample of the product. According to the Center for Disease Control, Salmonella affects about 1.2 million people per year. The four cake mixes are Classic White, Classic Butter Golden, Signature Confetti, and Classic Yellow, says Business Insider. The FDA said the Classic White Cake Mix isn't the definitive source of the salmonella outbreak.
