We study the quark flavor violating Higgs-boson decay $h \rightarrow \bar b s+ b \bar s$ in the Minimal Supersymmetric Standard Model (MSSM). The decay isanalyzed first in a model independent, and in a second step in the minimalflavor violationg (MFV) Constrained MSSM. The experimental constraints from$B$-Physics observables (BPO) and electroweak precision observables (EWPO) arealso calculated and imposed on the parameter space. It is shown that in somecases the EWPO restrict the flavor violating parameter space stronger than theBPO. In the model independent analysis values of ${\cal O}(10^{-4})$ can befound for ${\rm BR}(h \rightarrow \bar b s + b \bar s)$. In the MFV CMSSM suchresults can only be obtained in very restricted parts of the parameter space.The results show that it is not excluded to observe the decay $h \rightarrow\bar b s + b \bar s$ in the MSSM at future $e^+e^-$ colliders.
