What Temperature Is Required To Reduce Pathogens In an Animal Mortality Compost Piles?

Research studies have been done to correlate the temperature of a compost pile containing livestock or poultry carcasses and the amount of pathogen kill achieved at those temperatures. How do you take the temperature of a compost pile? And how does that temperature correlate to pathogen reduction?

Maintaining a temperature of 131 deg F for at least 4 hours assures us that we have reached an appropriate temperature for pathogen reduction. However, to destroy most pathogen and viruses, compost pile should sustain temperature 131 °F or greater for at least 3 consecutive days. The heat is the result of microbial metabolic activity within the compost pile as they are consuming the carcass.
