RAISED BEDS AND TANALISED WOOD

I have just built some raised beds as I am retiring and getting into the grow your own business, being old enough to remember the real taste of fruit and vegetables. With a new greenhouse and the raised beds which I made, I felt very proud, however I have just read in Grow It magazine about problems with raised beds made with Tanalised wood. How serious is the problem, do I need to replace them, line them in some way or is only a marginal problem, would hate to poison the family!

Beans/Peas/Carrots/Parsnips/Courgettes/Onions already planted

Thanks for any help or advice in advance.

It used to be tanalised with arsenic and chrome compounds which have now been outlawed, thankfully.
