We consider the contributions of new particles in supersymmetric theories to the nonleptonic decays of strange particles. We find that for a wide class of models the dominant new contribution is from purely ΔI = 1 2 penguinlike diagrams involving gluinos and scalar quarks. Detailed calculations suggest that these super-penguins are smaller in magnitude than the ordinary penguins unless the gluinos and scalar quarks are light (e.g. 1 GeV and 30 GeV, respectively), but there are significant uncertainties associated with higher order QCD effects.
