A gaseous blend of Ox and a method for significantly reducing the biological load, including anthrax, on mail and shipping parcels is disclosed. The gaseous blend of Ox consists at least in part of O<SUB>3</SUB>. The method involves applying a continuous stream of oxygen-containing, i.e., Ox, gas to the mail or shipping parcel at a predetermined temperature, pressure and relative humidity. The continuous stream of Ox gas is prepared in an Ox generation cell, which contains a means for generating the Ox gas at a pressure less than 20 lbs/in2 using, for example, one or more of the following: corona discharge, high frequency electrical discharge, ultraviolet light, x-ray, radioactive isotope and electric beam.
