We present a search for flavor changing neutral currents (FCNC) in decays of top quarks. The analysis is based on a search for t{bar t} {yields} {ell}'{nu}{ell}{bar {ell}} + jets ({ell},{ell}' = e, {mu}) final states using 4.1 fb{sup -1} of integrated luminosity of p{bar p} collisions at {radical} s = 1.96 TeV. We extract limits on the branching ratio B(t {yields} Zq) (q = u, c quarks), assuming anomalous tuZ or tcZ couplings. We do not observe any sign of such anomalous coupling and set a limit of B < 3.2% at 95% C.L.
