  Raman scattering spectra of zigzag spin chain TaFe$_{1.25}$Te$_3$ single
crystal are presented in a temperature range from 80 to 300 K. Nine Raman
active modes of $A_g$ and $B_g$ symmetry are clearly observed and assigned by
probing different scattering channels, which is confirmed by lattice dynamics
calculations. Temperature dependence of the Raman modes linewidth is mainly
governed by the lattice anharmonicity. The only deviation from the conventional
behavior is observed for $A_g$ symmetry modes in a vicinity of the magnetic
phase transition at $T_N \approx 200$ K. This implies that the electron-phonon
interaction weakly changes with temperature and magnetic ordering, whereas
small changes in the spectra near the critical temperature can be ascribed to
spin fluctuations.
