The topological term in the effective action for the electrically neutral BCS system is discussed. It is applied for the calculation of the transverse force acting on a vortex in the limit of a smooth vortex core and vanishing interlevel distance in the vortex core. The controversy between the topological terms in the articles by I. J. R. Aitchison et al. , Phys. Rev. B 51 , 6531 (1995) and A. van Otterlo et al. , cond-mat/9703124 is resolved.
