  Using quenched lattice QCD simulations we investigate the continuum limit of
baryon-strangeness correlation and other related conserved charge-flavour
correlations for temperatures T_c<T\le2T_c. By working with lattices having
large temporal extents (N_\tau=12, 10, 8, 4) we find that these quantities are
almost independent of the lattice spacing, i.e, robust. We also find that these
quantities have very mild dependence on the sea quark mass and acquire values
which are very close to their respective ideal gas limits. Our results also
confirm robustness of the Wroblewski parameter.
