Query: A cut that's a little too deep

I have been searching for a good cutting board for a while and I own 3 other boards (wood, glass and plastic). I was hoping that I would use this only for cutting raw meat, but after couple uses, the board was covered with rough cuts marks. I don't think it will affect the functionality but I am concerned with the plastic residue that might end up in my food. I guess I just have to wash the meat after I finish cutting it. A little disappointed!
