I have a new raised veg bed this year that is producing very well. However I used railway sleepers at the front and sides of the bed without really thinking about the danger involved from wood preservative leaking into the soil. Do you know if the veg will be contaminated and what I could do to rectify this now?

The chances are that the tar might cause root damage and foliage scorching.
The preservatives are plant poisons as well as human poisons, but if the plants are unaffected, they are probably okay, but not definitively okay.
Old sleepers are generally not used for vegetables for this reason.
