We consider the proton decay involving a light gravitino or axino in
gauge-mediated supersymmetry breaking models to derive constraints on the $R$
parity and baryon number violating Yukawa couplings. Bounds on all nine
coupling constants are obtained by considering the decay amplitudes at one-loop
order.
