Tito5, Thanks for the heads up on nut allergies, you got me curious and I deal with these questions working with Industrial hygiene at work. As far as I can find, generally, there has to be ingestion or respiration of the materials. Particularly as long as I seal it right there should be no problem. If you are curious here are two sources I looked up and my wife helped find: http://www.wood-database.com/wood-ar...-and-toxicity/
