We show that a process of concentration of baryon number (B) into restricted volumes, during the cosmological quark-hadron transition (Witten effect), should be present even if the transition temperature Tc exceeds 100 MeV and, rather, is stronger for higher Tc. If, however, quark nuggets do not form and B concentrations finally consist of large and localized baryon density peaks there still may be significant consequences for primeval nucleosynthesis and, in particular, present estimated limits on baryonic matter density, worked out from observed light element abundances, should be rediscussed.
