This comment is devoted to the recalculation of the Casimir energy of amassless scalar field in the Kerr black hole surrounded by quintessence derivedin [B. Toshmatov, Z. Stuchl\'{i}k and B. Ahmedov, Eur. Phys. J. Plus {\bf 132},98 (2017)] and its comparison with the results recently obtained in [V. B.Bezerra, M. S. Cunha, L. F. F. Freitas and C. R. Muniz, Mod. Phys. Lett. A {\bf32}, 1750005 (2017)] in the spacetime [S. G. Ghosh, Eur. Phys. J. C {\bf 76},222 (2016)]. We have shown that in the more realistic spacetime which does nothave the failures illustrated here, the Casimir energy is significantly biggerthan that derived in [V. B. Bezerra, M. S. Cunha, L. F. F. Freitas and C. R.Muniz, Mod. Phys. Lett. A {\bf 32}, 1750005 (2017)], and the difference becomescrucial especially in the regions of near horizons of the spacetime.
