What is required in Minnesota for a carcass compost facility?
Board of Animal Health rules require that composting facilities be constructed on an impervious pad using rot resistant materials. For best results, facilities should be covered with a roof and moisture levels should be maintained between 45 and 50 percent. Carcasses and litter should be layered so that a carbon:nitrogen ratio is established between 15:1 and 35:1 (optimal 23:1). To ensure pathogen reduction, compost piles must go through at least two heat cycles of greater than 130 degrees Fahrenheit.
