Holes in wood cutting board grain

I just got this amazing acacia end grain wood cutting board off Fb marketplace for $50 it was handmade and is 24 x 16 x 1 1/2 and is amazing the only problem is the cracks and holes in the grain and was wondering if there’s any way to fix them while being food safe and not standing out.
