BPA on its own is dangerous. An endocrine disruptor. Intake should be avoided at all cost. However, getting enough is not likely by using BPA containing packages. That is what USFDA thinks and so they regard BPA containing polycarbonate as safe for public use. Product manufacture using such material is getting back on track. Some are using approved by FDA slogan to cease peoples’ fear.
I quote again FDA stance.
Questions & Answers on Bisphenol A (BPA) Use in Food Contact Applications. Page Last Updated: 02/05/2016
Is BPA safe?
Yes. 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. People are exposed to low levels of BPA because, like many packaging components, very small amounts of BPA may migrate from the food packaging into foods or beverages. Studies pursued by FDA’s National Center for Toxicological Research (NCTR) have shown no effects of BPA from low-dose exposure.
On the other side, Enviromental Working Group remains firm against it. BPA is a synthetic estrogen. It can disrupt endocrine system even in small amounts. They emphasized, it may cause breast and reproductive system cancer, obesity, diabetes, early puberty, behavioral changes in children and resistance to chemotherapy. The last one is scary.
If we are going to side with EWG. Then, how can we avoid exposure? Sources can be easily spotted but avoidance is a daunting task. The substance is present in hard plastic, mostly polycarbonate. Plastic bottles usually has embossed identification, from 1 to 7. If it has none, then you are clueless. In my observation, most manufacturer opt to exclude ID.
BPA is also a component of epoxy resins. It is industrial adhesive and high-performance coating. Tin cans internal surface is always lacquered preventing contact of food with metal components. If that is the case, then, do we have the way to determine whether a canned foods is BPA free or not? I say “No”, unless the manufacturer explicitly claim they are using BPA-free packaging with accompanying certification.
