Bactericidal effect of hydrogen peroxide on Salmonella typhimurium in liquid whole egg.

The effect of hydrogen peroxide on Salmonella typhimurium in whole egg was evaluated. The bactericidal effects observed on the test organism at 5 degrees and 20 degrees C were found to be similar. There was a 99% kill in the presence of 0.5% and 1.0% H2O2. Addition of the test organism and H2O2 after pre-heating the egg material at 40 degrees C for 15 min caused a rapid kill which was 10,000-fold greater than that produced by H2O2 alone.
