We study the implications of the anomalous Z0 decays on neutrino counting in e+e- collisions. The {Mathematical expression} vertex is parametrized by an effective Lagrangian, Leff, satisfying U(1)em gauge invariance, CP and chirality conservation. The parameters of Leff are constrained by the ratio {Mathematical expression}, Bhabba scattering, and low energy vμe scattering data. We find that the effect on neutrino counting can be significant but depends on the magnitude and relative signs of the parameters in Leff. We also find that accurate measurements of the cross-section {Mathematical expression} at the Z0 peak can be used as a sensitive test for new physics.
