Notes:
—The recovery of polio virus inoculated into a variety of foods was studied as a function of four food processing operations: freeze dehydration, “pasteurization” by exposure to Cobalt-60 gamma irradiation, refrigerated storage at 4°C, and storage at 20°C. In general, a decrease in virus recovery was noted following each of the operations. Complete loss in recoverability was observed only in highly acid foods (below pH 2.9) stored at 20°C for 96 or 168 hr. Use of a DEAE Sephadex chromatographic column was found to have potential application for separation of virus foods.
