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 6^4, 8^4 and 10^4 for a variety of values of β and κ as well as the coefficient, h, of an explicit breaking term included in the action. We find that at β=6/g^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
... vor are spontaneously broken in the limit of zero h.
