Regulations can be headscratching at times, all the more so with FDA regulations. The latest example is the ban on BPA in infant formula packaging despite the fact that manufacturers have already voluntarily removed BPA from that packaging.
While the ban will ensure that manufacturer don't change their mind and move back to using BPA, the ban still makes little sense as the "...FDA said it still considers BPA to be safe for packaging, but took its action because manufacturers have already abandoned its use in baby formula packaging. The plastics and chemical industry also said the move had more to do with market forces than chemical safety."
So the FDA banned a safe material which no one is using anyway. I feel much safer. I'm glad to see that this agency has all the other serious issues of the day under control and can now be concerned about such minutia.
