We address some issues of renormalization and symmetries of effective field theories with unstable particles - resonances. We also calculate anomalous contributions in the divergence of the singlet axial current in an effective field theory of massive SU(N) Yang- Mills fields interacting with fermions and discuss their possible relevance to the strong CP problem.
