Googled this "BPA" and wikipedia has a ton of info on this....a lot of it is overhead reading - but it is totally worth checking out the whole article...come to find out the white plastic coating in canned foods and drinks/formulas is made with this stuff too! They are basicly saying that we know it's not good for you...but we don't know what levels...so we're gonna keep using it in everything except baby bottles till more studies are done! Comparing it to when they did studies on the chemicals in cigarettes and it took years for them to admit the truth...Great read!!!

Some type 7 plastics may leach bisphenol A
Some type 3 plastics may leach bisphenol A
There are seven classes of plastics used in packaging applications. Type 7 is the catch-all "other" class, and some type 7 plastics, such as polycarbonate (sometimes identified with the letters "PC" near the recycling symbol) and epoxy resins, are made from bisphenol A monomer.[4] When such plastics are exposed to hot liquids, bisphenol A leaches out 55 times faster than it does under normal conditions, at up to 32 ng/hour.[73] Type 3 (PVC) can also contain bisphenol A as antioxidant in plasticizers.[4] Types 1 (PET), 2 (HDPE), 4 (LDPE), 5 (polypropylene), and 6 (polystyrene) do not use bisphenol A during polymerization or package forming,[74] and thus will not leach bisphenol A into food or beverages.
