A set of procedures is given for avoiding the spurious anomalies that are generated when the 't Hooft - Veltman definition of gamma5 is used in conjunction with renormalization by minimal subtraction. These procedures are derived from the standard procedure, which requires in addition various finite renormalizations to remove spurious violations of chiral symmetry. They apply to open fermion lines, including flavor changing currents, to closed fermion loops, including those which contain true anomalous currents, and to anomalous loops connected to open fermion lines, to all orders in QCD.
