 The HyperCP experiment at Fermilab has collected the largest sample
 of hyperon decays in the world.  With a data set of over a million
 Omega-minus -> Lambda + K-minus decays we have measured the product
 of alpha(Omega)*alpha(Lambda) from which we have extracted alpha(Omega).
 This result indicates that alpha(Omega) is small, but non-zero.
 Prospects for a test of CP symmetry by comparing the alpha
 parameters in Omega and anti-Omega decays will be discussed.
