CNN reported two days ago that the FDA is saying BPA, or Bisphenol A, found in some reusable water bottles, baby bottles and most canned food is not dangerous.

Canada intends to be the first in the world to ban polycarbonate baby bottles. The news has been swarming about the possible dangers of the containers which appears to be tied to two types of cancer and early puberty.

The federal National Toxicology Program said Tuesday that experiments on rats found precancerous prostate tumors, urinary system problems and early puberty when the animals were fed or injected with low doses of the plastics chemical bisphenol-A.

When it comes to Bisphenol A (BPA) exposure from polycarbonate plastic bottles, it’s not whether the container is new or old but the liquid’s temperature that has the most impact on how much BPA is released, according to University of Cincinnati (UC) scientists.
