We show on general grounds that radiative mesonic decays, mediated through penguin-like diagrams, are expected to exhibit a significant enhancement from the exchange of supersymmetric particles. An interesting example is the decay b→sγ. An experimental bound BR(B→K*γ) ≤ 10-3 is presently available. It is however unclear whether K*γ represents the dominant mode for the inclusive b→sγ decay. We show that an upper bound BR(b→sγ) < 2 × 10-3 leads, for mt {reversed tilde equals} 45-80 GeV, to bounds on squarks and gluino masses comparable to the one coming from the analysis of the monojet events at the CERN pp̄ collider.
