  An extended chiral constituent quark approach, which embodies higher Fock
five-quark components in the baryons wave-functions, is employed to study the
sea quark content of the octet baryons. We report on the probabilities of
$\bar{u}$, $\bar{d}$ and $\bar{s}$ in the nucleon, $\Lambda$, $\Sigma$ and
$\Xi$ baryons, arising from the intrinsic five-quark states in the baryons wave
functions. Based on those probabilities, results for meson-nucleon
$\sigma$-terms; namely $\sigma_{\pi N}, \sigma_{K N}$ and $\sigma_{\eta N}$,
are presented.
