  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.
