Our place has a cutting board built into the countertop by the stove. We've been using it as a cutting board, but someone pointed out to me that I need to make sure it's unfinished (for safety) and that it requires proper maintenance.
How can I tell if it's safe to use for food? It looks like a normal cutting board to me, but I'm not experienced in the matter.
Looking up maintenance, sources said it depends on the kind of wood. Comparing to pictures it appears it could be maple (which is also common), but again, I am inexperienced in this regard.
