A hazard becomes a critical control point (CCP) when an unacceptable risk for the product quality can occur if this step is not monitored. In ultrasound food processing, parameters as temperature and physical properties of the product, time of treatment in ultrasound chamber, frequency and power of the ultrasound, naure of probe are points which need to be monitored. When each CCP is identified, their targets and limits are set. Then, a checking system must be set up to control so that the limits of the CCPs are not exceeded. This system gathers whole control procedures and general hygiene measures to undertake according to the tagets.
