We evaluate the matrix element of $\bar{q} q$ in hadron states on a lattice.
We find substantial mixing of the connected and disconnected contributions so
that the lattice result that the disconnected contribution to the nucleon is
large does not imply that the $\bar{s} s$ content is large. This has
implications for dark matter searches.
