The European Food Safety Authority (EFSA) has issued a further scientific opinion concerning the elimination from the body of the chemical bisphenol A (BPA), and how this relates to the risk assessment of BPA for humans. This opinion follows an undertaking by EFSA in May to review its previous advice on safe levels of BPA in food packaging, following new assessments from Canada and the US. Concerns have arisen over BPA as it has been found to migrate in small amounts into foods stored in materials containing the chemical.
EFSA concluded that after exposure to BPA the human body rapidly metabolises and eliminates the substance. In its previous risk assessment, EFSA established a tolerable daily intake (TDI) of 0.05 mg/kg body weight. A TDI is an estimate of the amount of a substance, expressed on a body weight basis, that can be ingested daily over a lifetime without appreciable risk. EFSA concluded that this TDI provides a sufficient margin of safety for the protection of the consumer, including foetuses and newborns, and that its previous risk assessment remains valid.
EFSA has confirmed that it will continue to monitor closely scientific findings regarding BPA and any related health effects.
