Taking into account the spin polarized and interface roughness scattering effect, within scattering formalism, we calculate the shot noise in the ferromagnet-superconductor tunneling junction. It is found that the ferromagnetic exchange interaction gives rise to decrease of the average current and the shot-noise power, but the interface roughness can give rise to increase of the average current and the shot-noise power.
