Any manual or guidelines on this topic will cover a number of subjects which have to be adjusted to the actual conditions of the country which may differ from the most simple countryside slaughter facilities to the most modern slaughterhouses. Machines and equipment may or may not exist in small slaughterhouses while modern slaughterhouses may have automatic equipment and machines.
Sanitation is the act or process of providing adequately hygienic conditions to ensure a safe, sound, wholesome product fit for human consumption and covers hygienic precautions regarding personal hygiene, process hygiene and cleaning and disinfection. Sanitation may also signify disinfection, but in this publication sanitation will be used according to the definition given above and disinfection as a reduction of the number of microorganisms.
Guidelines concerning cleaning and sanitation can be either theoretical or practical but here they will comprise a theoretical model for cleaning and disinfection and some practical examples for cleaning and disinfection of different kinds of slaughterhouses.
Furthermore the manual will contain a few guidelines concerning personal hygiene and process hygiene and give examples of the connection between personal hygiene, process hygiene and cleaning and disinfection.
