  The SUSY-EW one-loop quantum contributions to flavour-changing MSSM
Higgs-boson decays into $b \bar s$ and $s \bar b$ are computed and discussed.
We use the full diagrammatic approach that is valid for all $\tan \beta$ values
and do not rely on the mass-insertion approximation for the characteristic
flavour-changing parameter. We analyze in full detail the dependence of these
flavour-changing partial widths on all the relevant MSSM parameters and also
study the non-decoupling behaviour of these widths with the SUSY mass
parameters. We find that these contributions are sizable as compared to the SM
ones, and together with the SUSY-QCD contributions they can be very efficient
as an indirect method in the future search for Supersymmetry.
