The available data on and production from and pp collisions are reanalyzed with respect to an OZI rule violation on the basis of transition matrix elements. The data are found to be compatible with a constant ratio R, which however, deviates substantially from the SU(3) prediction based on the present knowledge of the mixing angle.
