One for animals, one for plants

I use two chopping boards in my kitchen, one for meat, chicken and seafood, and one for fruits and vegetables. A friend said it showed my OC-ness, but it makes perfect sense to me. Meat contains more bacteria than plants, and no way can anyone chop meat on my fruit and vegetable chopping board! The other way's alright, especially if the vegetables are meant to be cooked. But for salad vegetables and fruit, meant to be eaten raw, I will only use the chopping board that has never been touched by meat.
