  Within an extended chiral constituent quark formalism, we investigate
contributions from all possible five-quark components in the octet baryons to
the pion-baryon ($\sigma_{\pi B}$) and strangeness-baryon ($\sigma_{s B}$)
sigma terms; $B \equiv N,~\Lambda,~\Sigma,~\Xi$. The probabilities of the
quark-antiquark components in the ground-state baryon octet wave functions are
calculated by taking the baryons to be admixtures of three- and five-quark
components, with the relevant transitions handled {\it via} the $^{3}$P$_{0}$
mechanism. Predictions for $\sigma_{\pi B}$ and $\sigma_{s B}$ obtained by
using input parameters taken from the literature are reported. Our results turn
out to be, in general, consistent with the findings via lattice QCD and chiral
perturbation theory.
