It was pointed out recently that supersymmetry can generate flavor-changing gluonic dipole operators with sufficiently large coefficients to dominate the observed value of (Formula presented) We point out that the same operators contribute to direct (Formula presented) violation in hyperon decay and can generate a (Formula presented) violating asymmetry (Formula presented) in the range probed by the current E871 experiment. Interestingly, models that naturally reproduce the relation (Formula presented) do not generate (Formula presented) but could lead to an (Formula presented) of (Formula presented)
