Mexico bans Red 3 food coloring due to health concerns

Mexican health authorities have banned the use of the food coloring erythrosine, commonly known as Red 3, in food, beverages, and supplements. The decision, published in the Official Gazette of the Nation on May 28, 2026, follows findings by Cofepris indicating that the Mexican population's exposure to the substance exceeds the acceptable limit set by the World Health Organization (WHO).

Studies have shown that the estimated daily intake in Mexico is 0.231 mg per kilogram of body weight, more than double the WHO's Acceptable Daily Intake (ADI) of 0.1 mg per kilogram. The ban is based on toxicological concerns, as research has linked the substance to the induction of thyroid tumors in male rats.

Manufacturers have been granted a 24-month transition period to reformulate their products. During this time, products containing Red 3 may still be available in stores if they were manufactured before the deadline. The dye is frequently used in items such as gummies, gelatin powders, candies, ice cream, and various processed foods, many of which are highly consumed by children.
