We perform a measurement of the CP asymmetry in b{yields}s{gamma} decays using a sample of 383x10{sup 6} BB events collected by the BABAR detector at the SLAC PEP-II asymmetric B factory. We reconstruct 16 flavor-specific B decay modes containing a high-energy photon and a hadronic system X{sub s} containing an s quark. We measure the CP asymmetry to be -0.011{+-}0.030(stat){+-}0.014(syst) for a hadronic system mass between 0.6 and 2.8 GeV/c{sup 2}.
