As mentioned in my previous blog, below is the link to a write up by President of Consumer Association of Penang. Note that few points in his article:

1. Safe daily upper limit of BPA, as calculated by US Environmental Protection Agency (EPA) is 50 mcg /kg body weight. However, some studies report adverse health effects from exposures of only 0.025 microgram per kilogram of body weight per day.

2. A polycarbonate (PC) bottle with room-temperature water may leach two micrograms of BPA per liter. A 3-month-old baby drinking formula from a polycarbonate bottle containing BPA may be exposed to as much as 11 micrograms per kilogram of body weight daily.
Dear parents, sound scary, right? Imagine that our babies are taking milk feed above room temperature. What is the amount of BPA leached into the bottles?

3. We need to examine carefully the sponsor of those studies which claimed that BPA is safe.

4. Avoid BPA. Use either glass bottles, stainless steel bottle, or other safe alternatives such as bottle made of polyethersulfone (PES), polypropylene (PP).
