new pressure treated wood and edibles

Does anyone know how safe/dangerous the new pressure treated woods are, the ones without arsenic in their preservatives, when used as raised bed borders? And in particular, would they be dangerous when used in a fense a few feet from blueberry bushes. That is, would these new compounds make the berries unsafe to eat?
Thanks.

The new treated wood contains copper rather than arsenic salts. While still poison, they are most likely safer. I wouldn't worry about the blueberries. Remember they new treated wood must have stainless steel fasteners. Steve Steve Williams wrote in message ...
