We have analyzed experimental data on (i)e/sup +/e/sup -/ annihilation to hadrons, (ii) leptoproduction, (iii) hadron-hadron interactions, and (iv) heavy particle decays to determine SU(3) symmetry violation, i.e., the suppression factor (lambda) for strange quark-antiquark pairs relative to u anti u and d anti d pairs in the hadronic vacuum. Inclusive particle ratios, i.e., K/..pi.. ratios at large x and ratios between the inclusive production rates of relevant resonances, yield similar values for lambda, the weighted mean being < lambda > = 0.29 +- 0.02. No significant energy dependence of lambda is observed. We also find that the average net electric charge measurements for lepton produced quark jets are consistent with the above value of lambda.
