Environmental groups have been warning us about the risks of BPA -- a compound commonly found in plastic goods -- for years. The FDA says it has found no reason to ban or restrict its use so far, but a government research study done by the National Toxicology Program agreed with previous studies -- in lab animals, small doses of BPA does lead to precancerous prostrate tumors. Not only that, the chemical also causes urinary problems and early puberty in the animals.

Perhaps most alarming, BPA is found in popular brand name baby bottles, as well as the lining of cans and bottles of formula. It's also used in food containers, plastic water bottles, and dental sealants.

Sandy over at our sister site Parent Dish recently wrote a post about how to tell if your plastic is a safe one. If your product is hard and clear, chances are it contains BPA. You can also flip it over and look at the bottom. If its stamped with a 3,6, or 7, it's not safe for use. The numbers 1 and 5, however, are concerned safe for single use.

Parents have been feeding their babies with plastic bottle for years, but new evidence is emerging that clear plastic bottles may be harmful to a baby's health. It all comes down to a checmical known as bisphenol A, which The National Toxicology Program Center for the Evaluation of Risks to Human Reproduction is concerned can cause problems to fetuses in utero, including birth defects. The full report won't be available until later this year but they've provided a brief summary.

Meanwhile, bottle manufacturers have been quick to point out that the findings so far don't mention many major risk, so they're telling us to keep using plastic bottles. Do you think it's a good idea, or should we switch to something else in the interest of safety?
