Remember how it came out that the bisphenol-A found in many baby bottles was, according to one study, was dangerous and linked to cancer, obesity, diabetes? Now a group of parents in Ohio have sued five companies, claiming that the manufacturers knew that bisphenol-A (BPA) was dangerous, but did not disclose that to consumers.

The American Chemistry Council, which represents chemical makers including those that manufacture BPA, says that there is nothing to worry about and that BPA is safe, even for babies. According to Stephen Russell, plastics director for the ACC, government studies "have been strong, uniform and clear, that at the levels to which consumers are exposed, BPA base materials do not pose a risk to consumers."

Wal-Mart, the largest retailer in the world, however, decided to pull all bottles containing BPA despite the government's and trade group's assurances that it was safe. Toys R Us has done the same. I don't know if BPA is safe for babies or not, but it seems to me that this is one area in which it's easy enough to play it safe.
