We study 13 core-collapse supernova (CCSN) host galaxies at z = 0.1-0.6. Continuum observations at 250 GHz were performed using MAMBO at the IRAM-30 m telescope. No source is detected and the error-weighted mean flux is 0.25 +/- 0.32 mJy. Upper limits on their dust masses are derived and the corresponding sample mean corresponds to 1.4 +/- 2.2 x 10(8) M(circle dot). These results are comparable to previous submillimetre observations of SN-Ia hosts completed by Farrah et al. and Clements et al. We conclude that CCSN hosts are not extreme sources at millimetre wavelengths, and as confirmed using the optical luminosities of a subset of our sample, they are typical of the local galaxy population.
