barium carbonate question - help!

What should I do about pots already in use with a barium carbonate glaze? If
they don't discolor with a high-acid solution, does that mean that the barium
carbonate isn't leeching out and that the ware is safe for food? Is it just
that the barium carbonate is dangerous to the potter to work with but is safe
when it's fired correctly? Thanks in advance for helping...
