The study on the carcinogenicity of this natural black colorant is linked to its content of polycyclic aromatic hydrocarbons (PAHs) including benzoapyrene, a proven carcinogen (group 1 according to the classification of the International Agency for Research on Cancer). Given the very low exposure to benzoapyrene via the consumption of the dye E153, the European Food Safety Authority (Efsa) concludes that this is not a critical point. This analysis is also based on the history of the use of charcoal as a medicinal substance not absorbed in the gastrointestinal tract. Nevertheless, the Efsa concludes that it might be relevant to require the inclusion of the residual PAH content in the specifications of this dye.
