We study the breakdown of CPT symmetry which can occur in the decay process BB\ensuremath→l^\ifmmode±\else\textpm\fiX^\ensuremath∓f with f being a CP eigenstate. In this process, the standard model expectations for time-ordered semileptonic and hadronic events, i.e., which of the two decays takes place first, can be altered in the case that there is a violation of CPT symmetry. To illustrate this possibility, we identify and study several time-integrated observables. We find that an experiment with 109BB pairs has the capability of improving the bound on the CPT violating parameter or perhaps observe CPT violation.
