Nuclear electromagnetic charge and current operators have been recently derived from a chiral effective field theory (-EFT) with pions and nucleons. The calculation has been carried out up to include one-loop corrections. At this level of accuracy, the operators depend on the off-the-energy-shell prescription adopted for the non-static one- and two-pion-exchange potentials. Predictions for physical observables remain unaffected by the non-uniqueness of the operators, as they are related by a unitary transformation. Here, I will present this calculation and discuss the results obtained using the nuclear -EFT operators for a number of observables in A-4 nuclei.
