We discuss modifications to the concept of an ``antiparticle'', induced by a breakdown of the CPT symmetry at a fundamental level, realized within an extended class of quantum gravity models. The resulting loss of particle-antiparticle identity in the neutral-meson system induces a breaking of the EPR correlation imposed by Bose statistics. The latter is parametrized by a complex parameter controlling the amount of contamination by the ``wrong'' symmetry state. The physical consequences are studied, and novel observables of CPT-violation in ϕ factories are proposed.
