Once it's completely cured, it'll be fine. That said depending on the resin used and the climate it can take a really long time to set to the point that it's not toxic. Older resin is most definately slower setting than fresh. Depends on where you bought it, some pre-packaged small quantity resins can sit on the shelves for many years and can take forever to cure properly.
