  We calculate the decay width of h0 -> b bbar in the Minimal Supersymmetric
Standard Model (MSSM) with quark flavour violation (QFV) at full one-loop
level. We study the effect of scharm-stop mixing and sstrange-sbottom mixing
taking into account the constraints from the B meson data. We discuss and
compare in detail the decays h0 -> c cbar and h0 -> b bbar within the framework
of the perturbative mass insertion technique using the Flavour Expansion
Theorem. The deviation of both decay widths from the Standard Model values can
be quite large. Whereas in h0 -> c cbar it is almost entirely due to the
flavour violating part of the MSSM, in h0 -> b bbar it is mainly due to the
flavour conserving part. Nevertheless, the QFV contribution to Gamma(h0 -> b
bbar) due to scharm-stop mixing and chargino exchange can go up to about 8%.
