We search for the flavor-changing neutral current decays of the top quark t{yields}q{gamma} and t{yields}qZ (here q represents the c and u quarks) in p{ovr p}p collisions at sqrt[s] = 1.8 TeV. We use a dataset ({integral}Ldt{sup -}110 pb{sup -1}) collected during the 1992-1995 run of the Collider Detector at Fermilab. We set 95% confidence level limits on the branching fractions B(t{yields}q{gamma})<3.2% and B(t{yields}qZ)<33%, consistent with the standard model.
