The available data on $\omega$ and $\phi$ production from ${\pi}N$ 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 $\phi{-}\omega$ mixing angle.
