RIVM expressed concerns on the effects of bisphenol a (BPA) on the immune system in a report issued in March 2016. Consequently, the Dutch minister of Health, Welfare and Sport, Edith Schippers, requested EFSA to consider this issue. EFSA states that the new evidence highlighted by RIVM adds to the indication already reported in 2015 that BPA might affect the immune system in animals, but is too limited to draw conclusions on human health.
In 2017, EFSA will begin a new
BPA assessment with a view to
reconsidering the temporary tolerable daily intake (TDI) of this
substance.
BPA is a substance that occurs in
numerous products. It is used in plastics for i.e. construction
material, electronics, plastic bottles, (food) packaging material,
toys and medical devices. BPA is
also used as a base for epoxy-coatings, adhesives and in specific
dental care products and as a dye developer in thermal paper, such
as cash register receipts.
More stringent European standards for safe exposure of workers and
consumers to BPA were proposed in 2014 and 2015. In
March, RIVM concluded that new insights sufficiently warrant
consideration of even more stringent standards and recommended to
take additional measures to a further reduce BPA exposure.
Food intolerances and infectious diseases
According to RIVM,
BPA may impair the immune system
of unborn and young children at a lower exposure level than the one
on which the current standards are based. If these effects occur,
children would have a greater probability of developing food
intolerances and would become more susceptible to infectious
diseases.
Awaiting the revised standards, RIVM
has proposed to reduce exposure to BPA wherever possible. Examples of how this
can be done are educating pregnant women, reducing the quantity of
BPA that is released from products
containing the substance and development of safe
alternatives. Additionally, workers can be protected against
BPA exposure.
Scientific studies
There are differences in the way EFSA and RIVM
evaluated the two scientific studies by Menard et al. on the effect
of BPA on the immune system. This
may be due to the fact that EFSA, unlike RIVM,
had access to the original study data. The evaluation of these
studies at the international workshop organised by RIVM
is documented by Hessel et al. (2016).
