We study the flavor changing neutral current decays of the MSSM Higgs bosons into strange and bottom quarks. We focus on a scenario of minimum flavor violation here, namely only that induced by the CKM matrix. Taking into account constraint from b→ s γ, δρ as well as experimental constraints on the MSSM spectrum, we show that the branching ratio of (Φ→ bs) and (Φ→ bs) combined, for Φ being either one of the CP even Higgs states, can reach the order 10-4-10-3 for large tanβ, large μ, and large At. The result illustrates the significance of minimal flavor violation scenario which can induce competitive branching fraction for flavor changing Higgs decays. This can be compared with the previous studies where similar branching fraction has been reported, but with additional sources of flavor violations in squark mass matrices. We also discuss some basic features of the flavor violating decays in the generic case.
