A friend of mine is an employee of the FDA. He said that no official word has been released, but what's going around his office after recent tests is a couple things (just in the interest of full disclosure, he works in the section that tests medications, not the section that tests things like this)...
- Colored thick plastic rigid bottles (think Nalgene) are the ones that leach BPA
- Bottles with water/other liquid in them exposed to very high temperatures for extended periods of time are the only ones that leached BPA
I was asking him about it since I had heard the same things as everyone else. He said they are discovering that there is very little danger from bottles that are flexible like bike water bottles or the ones that you buy water in at the gas station.
I don't claim to be an expert of course, so I'm just passing on what he told me.
