Formaldehyde is a surface disinfectant; therefore, it is important to destroy microorganisms while they are still on the surface of the egg shell. It is also important that the shell is not covered in dirt. The fumigant will not sanitise underneath the dirt.

  • Don’t use too much product

Disinfection rates must be to the limits of the supplier. The manufacturers spend a lot of money investigating optimal use of their products so double dosing is ineffective and can be dangerous.

  • Fumigate as soon as possible at the hatchery

Once the harmful organisms penetrate the shell, they reach the shell membrane within minutes and are protected from the fumigant. Thus, fumigate the eggs as soon as possible, preferably on arrival at the hatchery. 

Do not fumigate after egg handling, right before setting. Firstly, the bacteria have probably already entered the egg and secondly the young embryonic germ is very...
