We study the quark flavor violating Higgs boson decay h→bs+bs in the minimal supersymmetric standard model (MSSM). The decay is analyzed first in a model-independent approach and second in the minimal flavor violating (MFV) constrained MSSM. The experimental constraints from B-physics observables (BPO) and electroweak precision observables (EWPO) are also calculated and imposed on the parameter space. It is shown that, in some cases, the EWPO restrict the flavor violating parameter space more than the BPO. In the model-independent analysis, values of O(10-4) can be found for BR(h→bs+bs). In the MFV constrained MSSM (CMSSM), such results can only be obtained in very restricted parts of the parameter space. The results show that observation of the decay h→bs+bs in the MSSM at future e+e- colliders is not excluded.
