Sources, vehicles and routes of contamination

Sources, vehicles and routes of contamination 

 of contamination depends on either removing the sources, or putting barriers between them and the vehicles or between them and food. Thus human access to food must be restricted, raw foods handle in separate areas, vermin excluded and work ares enclose in suitably constructed and Sources, vehicles and routes of contamination ventilated rooms.

Similarly, vehicles must, where possible, be excluded. Handling should be minimised, wiping cloths used sparingly or destroyed after each use, hand-contact surfaces, such as tap handles, replaced with knee or electronically operated taps, and the number of surfaces with which the food comes into contact limited.

In the nature of food preparation, however, routes between sources and vehicles survive, giving rise to contaminated vehicles. Consequently, routes must be disrupted by cleaning and disinfection. For example, should a work surface come into contact with contaminated source, raw meat for instance, the surface must be cleaned and disinfected before it is used for cooked meat.
