EFSA said it reduced the tolerable daily intake level because the “method used to assess the risk from BPA has become more refined than the one” used in previous evaluations.
Uncertainty concerning skin absorption
For the first time, EFSA said, it also considered exposure to BPA from non-dietary sources. EFSA expert Trine Husoy acknowledged “there is a lack of supporting data” on how much the body absorbs through the skin, which “really increases the uncertainty of estimates from thermal paper and cosmetics.”
Besides being used for can liners and re-usable plastic tableware, BPA is also commonly used in cashier slips and ATM receipts, CDS and DVDs as well as plastic containers used for microwave cooking or fridge storage.
Some studies have linked it to brain and nervous system problems, reproductive disorders and obesity. A study in 2013 said it may expose unborn children to breast cancer later in life. The substance has been banned for use in baby bottles by the European Union, the United States and Canada, and from all food containers in France from the beginning of this year.
EFSA said that in calculating its tolerable daily intake levels for BPA, in factored in the potential effects of the compound on mammary glands as well as the reproductive, metabolic, neuro-behavioural and immune systems.
