We examine the effect of the difference in nuclear interactions of K0 and K ̄0 mesons on the measurement of CP asymmetry for experiments at e +e - colliders-charm and B-meson factories. We find that this effect on CP asymmetry can be as large as 0.3%, and therefore sufficiently significant in interpreting measurements of CP asymmetry when neutral kaons are present in the final state.
