Dear Green {Goody},
How can I tell if my plastic bottles contain BPA?

- Sarah M., Kansas

Simply turn your bottle over. If your bottle is polycarbonate, the clear hard plastic and has a #7 recycling code on the bottom with the letters PC, then it contains bisphenol-A or BPA. Bisphenol-A is a harmful chemical that can leach into our food and water, being exposed to BPA increases the amount of estrogen in the body, which could cause health issues such as infertility or cancer.
