Comment on “Casimir force acting on magnetodielectric bodies embedded in media”

It is shown that the Raabe and Welsch [Phys. Rev. A 71, 013814 (2005)] criticism of the Dzyaloshinskii-Lifshitz-Pitaevskii theory of the van der Waals--Casimir forces inside a medium is based on misunderstandings. It is explained why and at which conditions one can use the ``Minkowski-like'' stress tensor for calculations of the forces. The reason why, in my opinion, the approach of Raabe and Welsch is incorrect is discussed.
