The $\mathrm{CP}$-violating (CPV) kaonic matrix elements ${\epsilon }^{\prime }$, $\mathrm{Im}{A}_0$, and $\mathrm{Im}{A}_2$ are used to compute CPV observables in baryonic systems. The numerical results for the electric dipole moment and the difference between $\Lambda$ and $\overline{\Lambda }$ decay parameters are similar to other approaches that use quark operators. Relations between the neutron electric dipole moment, CPV pion-nucleon coupling constants, and $\Lambda$-decay parameters are derived.
