It is possible that CPT-violating amplitudes with sizes of order m{sub K}/ m{sub Planck} contribute to processes involving K mesons. We describe several tests of CPT invariance that could be carried out at the Fermilab Main Injector. To our surprise we find that one experiment, a precision measurement of the CP-violating charge asymmetry in semileptonic K decays, can be performed with sufficient statistical accuracy to detect the presence of CPT-violating amplitudes of size m{sub K} / m{sub Planck} which generate a mass difference between K{sup 0} and {bar K}{sup 0}. 10 refs.
