    We present a study of Zγ+X production in pp̄ collisions at √s=1.8 TeV from 97 (87) pb-1 of data collected in the eeγ (μμγ) decay channel with the D0 detector at Fermilab. The event yield and kinematic characteristics are consistent with the standard model predictions. We obtain limits on anomalous ZZγ and Zγγ couplings for form factor scales Λ=500 GeV and Λ=750 GeV. Combining this analysis with our previous results yields 95% C.L. limits |hZ30|<0.36, |hZ40|<0.05, |hγ30|<0.37, and |hγ40|<0.05 for a form factor scale Λ=750 GeV.
