I heard on the news this morning, that we should avoid bottles with a '7' in the recycle logo at the bottom of the bottle. I threw mine out today. I don't like those hard bottles anyway. I need something I can squeeze and that has a pop top lid.

I found this.

Bisphenol A, or BPA, allows manufacturers to make a rigid and translucent product known as polycarbonate plastic, often - but not always - identified by a triangle surrounding the number 7. In canned food and beverages, especially acidic vegetables and fruits, BPA-resin liners stop the contents from eroding the metal container.

Canadian retailers have been pulling bottles from the shelves since the announcement was made. They clearly won't be waiting for the ruling to come down.
