Accurately calibrated gauges/recorders must be used to monitor continuously the processing conditions. Records must be kept to show the date of calibration of gauges/recorders.

Material that may not have received the specified heat treatment, such as material discharged at start up or leakage from cookers, must be recirculated through the heat treatment or collected and reprocessed or disposed of in accordance with Regulation (EC) No 1069/2009.

1. (a)

   raw material particle size;

2. (b)

   temperature achieved in the heat treatment process;

3. (c)

   pressure, if applied to the raw material;

4. (d)

   duration of the heat treatment process or feed rate to a continuous system. Minimum processing standards must be specified for each applicable critical control point.

In the case of chemical treatments which have been authorised by the competent authority as processing method 7 in accordance with point G of Chapter III, the critical control points that determine the extent of the chemical treatments applied shall include the pH adjustment achieved.

Records shall be maintained for at least two years to show that the minimum process values for each critical control point are applied.

Category 3 material shall be processed in accordance with any of the processing methods 1 to 5 or processing method 7, or, in the case of material originating from aquatic animals, with any of the processing methods 1 to 7, as referred to in Chapter III.
