Being vegetarian or vegan doesn't mean not eating anything that contains molecules that previously were meat. It means not eating anything that is an animal product. By definition decomposers are converting the animal products into basical minerals and nutrients because THEY are eating the meat. Otherwise plant matter couldn't even be eaten because some of the carbon has been through the carbon cycle and was previously an animal.
