Heaping of used poultry litter produces elevations in temperature that lead to a significant reductions in pathogen load, analogous to pasteurisation. The speed and degree of heating varies with depth in the heap and with a range of factors that can be influenced by management. These include heap size, moisture content, turning and covering. In broad terms smaller heaps heat more quickly and are more appropriate for shorter pasteurisation periods. Turning of heaps is only beneficial for pasteurisation periods of longer than 7 days and potentially detrimental for periods of 6 days or shorter. On the other hand the benefits of covering heaps are reduced with longer pasteurisation periods. Addition of moisture is rarely needed and never required if covers are used. This paper summarises the effects and interactions between these practices and concludes with a brief suggested operating procedure.
