We present data testing the existence of a parity-flavor-breaking phase in simulations of QCD with two flavors of light Wilson fermions. This is done by explicit simulations on lattice sizes of 6{sup 4}, 8{sup 4}, and 10{sup 4} for a variety of values of {beta} and {kappa} as well as the coefficient h of an explicit breaking term included in the action. We find that at {beta}=6/g{sup 2} equal to or greater than 5.0 extrapolation in the parameter h as well as in the lattice volume show no indication of a phase where parity and flavor are spontaneously broken in the limit of zero h. {copyright} {ital 1997} {ital The American Physical Society}
