We study the lepton flavor violating (LFV) decays Z-> l_i l_j(l_{i,j}=e,\mu,\tau) in the framework of the minimal 331 model. The maincontributions arise at the one-loop level via a doubly charged bilepton withgeneral LFV couplings. We obtain an estimate for the corresponding branchingratios by using the bounds on the LFV couplings of the doubly charged bileptonfrom the current experimental limits on the decays l_i-> l_j\gamma and l_i->l_j l_k l_k. A bound on the bilepton mass is also obtained through the currentlimit on the anomalous magnetic moment of the muon. It is found that thebilepton contributions to LFV Z decays are not expected to be at the reach ofexperimental detection. In particular, the branching ratio for the Z-> \mu \taudecay is below the 10^{-10} level for a bilepton mass of the order of 500 GeV.
