We report on the detection of [OI] emission lines in the high-resolution optical spectra of several Magellanic Cloud (MC) B[e] supergiants, which we took with FEROS at the ESO 1.52m telescope in La Silla (Chile). In addition, we model the [OI] line luminosities and show that the best location for the neutral oxygen material is the outflowing disk. In order to reproduce the observed line luminosities, we conclude that the disks must be neutral already very close to the stellar surface.
