Abstract:

The effectiveness of egg dipping in a 6% hydrogen peroxide 
solution to eliminate Salmonella typhimurium from eggshell 
membranes was evaluated. The first step was to assess the 
water uptake from broiler hatching eggs dipped in tap water 
once or twice using a positive-pressure differential method 
in order to determine the best method to use in the disinfection 
trials. Double dipping increased water uptake by 86% more 
than single dipping. Dipping S. typhimurium-contaminated 
eggs twice in a 6% hydrogen peroxide solution reduced the 
average number of organisms in eggshell membranes by 95% 
and the number of S. typhimurium-positive eggs by 55% compared 
with the infected untreated group. Dipping the eggs in 
a 6% hydrogen peroxide solution did not adversely affect 
hatchability.
