We compute the decay width of $h^0 \to c \bar{c}$ in the MSSM with quarkflavor violation (QFV) at full one-loop level in the $\overline{\rm DR}$renormalization scheme. We study the effects of $\tilde{c}-\tilde{t}$ mixing,taking into account the constraints on QFV from the B meson data. We find thatthe full one-loop corrected decay width $\Gamma(h^0 \to c \bar{c})$ is verysensitive to the MSSM QFV parameters. In a scenario with large$\tilde{c}_{L,R}-\tilde{t}_{L,R}$ mixing, $\Gamma (h^0 \to c \bar{c})$ candiffer up to $\sim \pm 35\%$ from its SM value. After estimating theuncertainties of the width, we conclude that an observation of these QFV SUSYeffects is possible at a future $e^+ e^-$ collider such as ILC.
