We compute the finite ma corrections associated with the measurement of sea quark matrix elements on the lattice. The results differ from the (1+ma) correction factor commonly used for valence quarks and connected current insertions. We find that for sea quarks the correction factors are in general larger and depend strongly on the Lorentz structure of the current under consideration. Results are presented both for the Wilson action and for the two-link improved action of Hamber and Wu. Phenomenological implications are also briefly discussed in two examples.
