EFSA reviews consumer exposure to bisphenol A

EFSA’s scientific experts have provisionally concluded that for all population groups diet is the major source of exposure to bisphenol A (BPA) and exposure is lower than previously estimated by EFSA. BPA is a chemical compound used in food contact materials such as packaging as well as in other consumer products. This is the Authority’s first review of exposure to BPA since 2006 and the first to cover both dietary and non-dietary sources (including thermal paper and environmental sources such as air and dust). As part of a two-stage process of its full risk assessment, EFSA is now seeking feedback on this draft assessment of consumer exposure to BPA. During a later phase, EFSA will publicly consult on the second part of its draft opinion, focussing on its assessment of the potential human health risks of BPA.

New data resulting from an EFSA call for data led to a considerable refinement of exposure estimates compared to 2006. For infants and toddlers (aged 6 months-3 years) average exposure from the diet is estimated to amount to 375 nanograms per kilogram of body weight per day (ng/kg bw/day) whereas for the population above 18 years of age (including women of child-bearing age) the figure is up to 132 ng/kg bw/day. By comparison, these estimates are less than 1% of the current Tolerable Daily Intake (TDI) for BPA (0.05 milligrams/kg bw/day) established by EFSA in 2006.

For all population groups above three years of age thermal paper was the second most important source of BPA after the diet (potentially accounting for up to 15% of total exposure in some population groups).

Among other key findings, scientists found dietary exposure to BPA to be the highest among children aged three to ten (explainable by their higher food consumption on a body weight basis). Canned food and non-canned meat and meat products were identified as major contributors to dietary BPA exposure for all age groups.
