Since the inception of artificial incubation of poultry hatching eggs, sanitation has been a key concern. Optimal hatch requires high levels of cleaning and disinfection, and one of the main chemicals used in poultry hatcheries is formaldehyde. Formaldehyde is a carcinogenic chemical and can be toxic to both hatchery employees and chicks when used improperly. The purpose of the following research was to study Dry Hydrogen Peroxide (DHP) and its potential as a safe, yet effective, alternative to formaldehyde. DHP machines were installed throughout a broiler hatchery equipped with single stage HatchTech incubators, and a 12-month trial was completed. Hatchability among the group of eggs treated with DHP was comparable to the group treated with formaldehyde. Additionally, eggs exposed to DHP during all 19 days of incubation had significantly less microbes present on their shell surfaces at transfer when compared to non-treated eggs.
