Resumen:
We show that the eta gamma Z anomaly can be measured by analysing parity-violating effects in the  eta -> gamma mu+ mu- decay. In this sense, we find that the longitudinal polarization of the outgoing mu+ is an appropriate observable to be considered in future high-statistics eta factories. The effect is expected to lie in the range 10^-5 - 10^-6 in the Standard Model.
