In the context of in ovo vaccination, a comprehensive and regular Hygiene Monitoring Program is recommended. Hygiene regular monitoring through microbiological screening of the hatchery assessed for absolute microbial loading, is the best tool for the following objectives:

  • Getting a real picture of the sanitary status of the hatchery
  • To evaluate the efficacy of the cleaning and disinfection protocols in place
  • To identify  the source, type and origin of an eventual contamination on the production
  • To identify the critical points of the production flow
  • Getting a clear idea of which are the sanitary procedures to be improved
  • To set an alert system about eventual increases in the contamination levels 

It is important to note that hygiene control in a hatchery is essentially a result of cleanliness complemented by disinfection. A disinfectant, whether used as a solution, gas or aerosol, will not compensate for cleaning deficiencies or for a difficult to achieve cleaning programme according to design of the hatchery.

Sanitation during the in-ovo process : Water Quality

It is fact that the quality of water is also key not only for equipment sanitizer but also for equipment and accessories cleaning.

Knowing about water treatments is also important to make sure sanitation is properly done. 


Distillation, demineralization or Reverse Osmosis are the most commonly used methods of water treatment that can be recommended according to the needs. 

For example, absence of bacteriological load in the distilled water can be mandatory for the dedicated containers of distilled water  because no disinfectant will be used. If not the case, low levels of bacteria can colonize the tubing of the on-board cleaning system, especially if the water is accessed through a hose or tanks with low hygiene standards.

In other cases, low mineralization of water is recommended also specially for the external cleaning of the equipment as the idea is to avoid any mineral formation and rust formation that may deposit in the system and surfaces. 

The hygiene monitoring program is put in place by the regular hatchery visits included in the in ovo C.H.I.C.K Program services to monitor the efficacy of the measures taken and its impact on the in ovo process and hatchery performance.
