  Electric charge and color breaking minima along third generation squark
directions do appear in the Minimal Supersymmetric Standard Model for
particular regions of the corresponding supersymmetric parameters $A_t$, $\mu$,
$\tan\beta$, $m_Q^2$ and $m_U^2$. We have studied possible instabilities of
electroweak sphalerons along non-trivial squark configurations. We have found
that instabilities along the latter lie in the region of parameter space where
the electroweak minimum is not the global one. Thus charge and color
conservation imply that the standard electroweak sphaleron is not destabilized
along squark directions.
