Abstract
The bactericidal properties of an iodine liquid and an iodine powder detergent sanitizer were found to he practically equal. At 25 ppm. of available iodine both products compared favorably with 100 ppm. of available chlorine in killing E. coli, S typhosa, M. pyogenes var. aures and Ps. aeruginosa, in the presence of hard water, whole milk, and dishwash soil. The iodine detergent-sanitizers can be recommended for sanitizing food utensils, if field tests substantiate results of the laboratory performance tests.
