Square food gardening question

Square food gardening question

Question for anyone who does square foot or raised bed gardening: I have some boards, probably old ceder, that were salvaged from an old (probably 1930's or earlier) outbuilding that collapsed. Is there any reason not to use these to build my raised beds? Is there anything that they might have been treated with that I should be concerned about?
