From Food Navigator:
Proponents of BPA, the resin found in the linings of canned food and baby bottles, maintain its safety. The plastic and food packaging industries argue that the compound is cost effective and durable and that there are no effective alternatives. But is the evidence against BPA beginning to stack up?
What you need to know:
Bisphenol-A (BPA) is suspected of being hazardous to humans since the 1930s, and many parents choose to feed their babies with BPA free bottles. Now the controversy has reached canned foods as well.
What to look for at the Supermarket:
Unfortunately, there isn’t a way to know if a product package has BPA in it. At the behest of consumer groups this may change.
