SACRAMENTO, Calif. — The International Association of Color Manufacturers (IACM), which represents both color manufacturers and consumer product companies that use color, believes that the safety of the food and drug supply is of paramount importance to all consumers, including children. IACM appreciates the ongoing need to conduct research into possible effects any food ingredient may have, including colors. 

However, the Office of Environmental Health Hazard Assessment (OEHHA) assessment does not establish a causal relationship between synthetic colors and negative health or behavior effects, and its conclusion that an association may exist are based on insufficient scientific evidence 

Colors are safely used in a wide variety of consumer products, are among the most widely studied food ingredients, and are subject to strict global regulatory requirements. The U.S. Food and Drug Administration (FDA) and international regulatory bodies have all concluded that synthetic dyes are safe for children and no study has offered compelling evidence that these colors cause adverse behaviors.  

Any risk management actions such as a warning label would be scientifically unfounded and unnecessary. US regulations already require that every color be clearly listed on the label by name.  A warning statement based on inconclusive science would not provide meaningful impact to Californians but would mislead consumers and undermine consumer confidence in a safe food supply. Parents of children who may be sensitive to food ingredients, including colors, can avoid such foods in consultation with their doctor based on existing ingredient declarations and labeling requirements.


OEHHA has published a final hazard assessment after being tasked to conduct “a risk assessment of the potential impacts of synthetic food dyes on children, particularly for neurobehavioral and other neurologic effects.  IACM thoroughly reviewed the draft assessment and provided extensive feedback during the public comment period that ended November 12, 2020. 

While OEHHA concludes that effects may exist for all FD&C colors, the studies evaluated in the OEHHA assessment do not support a relationship between exposure to any food dyes and hyperactivity or neurologic effects in children. Additionally, OEHHA inappropriately treats all synthetic colors similarly when each have different chemical attributes and effects.   

After reviewing studies that suggest associations between exposure to FD&C colors and adverse behavior in children, the FDA, Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have all concluded that current evidence does not establish a causal relationship, nor does it warrant additional risk managementMost recently in October 2019, the FDA similarly concluded that there remains insufficient evidence to establish a causal link between synthetic color intake and adverse behavioral outcomes.
