Color stain coming off cutting board
Welcome to SA!
If the red coloring is wiping off, I personally wouldn't use it for food unless I could contact the maker and find out how they dyed it.  Given that they didn't know enough to seal the dye well enough to keep it from seeping, I wouldn't trust that they knew enough to choose a non-toxic dye.  And while some wood dyes are non-toxic, others are extremely toxic, even from the same source.
