Bisphenol A (BPA)
is a plasticizer used as the structural component of many plastic containers,
beverage bottles and lining of food cans. Its optical clarity makes BPA
suitable for making components of many medical devices and their housing. Products
like bike helmets, police shields, reading glasses and bullet-proof glass
contain BPA for its shatter proof properties. These are just a few examples of
products that can expose us to BPA. BPA is toxic if ingested, inhaled or if it gets
into our bodies through skin contact. If products containing BPA are heated, it
decomposes and emits acrid and irritating fumes that can cause an allergic
reaction.
BPA can leach
out of containers and get into our food and drinks. BPA is known to disrupt
normal hormonal activity and cause infertility. If it gets into our water
system, it is toxic to aquatic life. Use of plastics in day-to-day life is
increasing and as a result exposure to BPA is also increasing. Reports show
that BPA level in human blood and tissues, including in human fetal blood, is
higher than the proposed safe levels by the FDA. Long term effect of exposure
to BPA in adulthood or during fetal life is that it alters neurobehavioral
development. The FDA released a statement saying that BPA is safe at the
current levels occurring in foods. Based on FDA’s ongoing safety review of
scientific evidence, the available information continues to support the safety
of BPA for the currently approved uses in food containers and packaging.
What we can do
to reduce exposure to BPA is to seek BPA-free products and reduce use of canned
foods and avoid exposing plastic containers to heat by not putting them in the
microwave or dishwasher. We can also use alternatives like glass, porcelain or
stainless steel containers for hot foods and liquids instead of plastic
containers.
