# $sss$ decay and violation of strangeness

Why can the hyperon $\Omega^{-}$ not decay by strong interaction? It seems that strangeness must be violated, but why is it the only way?

As an answer to the second question, strangeness tends not to be conserved in weak interaction or decay. – Meow Oct 29 '12 at 12:19
Are you looking for something beyond "Because the strong interaction respects flavor."? If so, can you be more specific? – dmckee Oct 29 '12 at 13:01
