This study was carried out to determine the combined sporicidal effects of relatively low concentrations of hydrogen peroxide and iodophor on the spores of Closfridium sporogenes . Such treatments may be useful in sterilizing bulk storage tanks. The spores were dried on epoxy coated penicylinders and were treated with 1, 3, 5 or 10% hydrogen peroxide for 1 or 2 hr at 15° or 50°C followed by a prolonged treatment with iodophor (25 ppm). The data indicate that at 15° C, treatment with 5% hydrogen peroxide alone would not produce sterility; however, when this treatment was followed by an iodophor soak for 24 hr, sterility was obtained.
