CCA treatment is to control insect infestation primarily termites and carpenter ants. I have read lots of stuff by manufacturers stating it's fine for plants and people. Then I saw a local (to me) story where a playground had to be closed because of ultra high levels of arsenic in the soil leeching from the PT wood from the structures. If the manufacturer thinks it is safe than perhaps they wouldn't mind eating all of their food from CCA treated wooden plates. Remember this is a chemical combination designed to KILL THINGS. CCA does not prevent rot.

Why don't you use regular (non treated) pine? It is cheaper, less toxic and just as available and the splinters do not hurt nearly as much.
