In this proceeding I briefly review current status of the construction of nuclear electro-weak
currents within chiral effective field theory. I show that gauge and chiral symmetry requirements lead
to the well-known continuity equations for the current and charge
operators which, however, get modified at higher
orders. Regularization of the current will be also
discussed. I demonstrate that implementation of a cutoff
regulator in a naive way leads to violation of chiral symmetry. To respect the underlying symmetries I propose to use higher derivative regularization in the nuclear forces and currents.
