No problem at all, I hope any or some of my info helped.
Yes, there has been a ban since 1975 (wether I agree or not isn't the issue)
Here is a great link with some info straight from the Center of Veterinary Medicine from the US FDA:

This is always good for anyone in the turtle / tortoise hobby.
Hope this explains a little more about the laws regarding.
There are always things you can do in the LEGAL manner if you or anyone else doesn't agree with this law. Again being a responsible keeper is always step number one. (Easier to get your issue across when you're being a responsible party in our hobby)
Sorry just went on a sideways rant, but again hope this helps,
Thanks
