We have searched for baryon-containing radiative penguin decays in 9.7 × 106
events collected at the Υ(4S) with the CLEO detector. We find no evidence for such decays, and set a 90% confidence level upper limit of 
. Corrections to CLEO’s recent b → s
γ measurement due to 
decays are well within the errors quoted. A search for semileptonic decays of B mesons to 
inclusive final states in the same data sample found no evidence for such decays and set an upper limit of 
. These limits suggest that external W emission is not the dominant source of baryon production in B decay.
