The U.S. Food and Drug Administration (FDA) has officially banned the use of Red Dye No. 3 in foods, drinks, and some medicines, citing concerns over potential cancer risks identified in animal studies. This controversial artificial dye, which has been linked to health issues, will no longer be allowed in various products including candies and cereals. Food manufacturers are required to comply with this ban by 2027. The decision comes decades after similar concerns prompted its removal from cosmetics, sparking a broader debate on food additives in the U.S. The ban raises questions about remaining synthetic dyes still permitted in food and highlights ongoing discussions about food safety and health regulations.
