Assuming that the Fermions are of parity mixing, the possibility of reconciling the parity conservation with the strangeness conservation in the Yukawa type interaction between hyperons and mesons is investigated. This can be done when all interactions are of VA-type or of SPT-type exclusively. If there is, at any rate, one evidence of VA-type interaction, then all other interactions, both weak and strong, should be of VA-type. As the weak interactions are agreeable to VA-type from the estimation of the degree of the parity violence, it is concluded that the interactions under consideration are exclusively of VA-type. The introduced parameter indicating the rate of parity mixing can be estimated from an anisotropy of the decay interaction.
