Swine Carcass Disposal Options for Routine and Catastrophic Mortality

CAST papers are the foundation of CAST’s science communication work. Developed by expert-led task forces, these peer-reviewed publications translate agricultural science into trusted insights that inform policy, guide public understanding, and fuel CAST programs, dialogues, and educational initiatives.

Abstract

This Issue Paper provides a critical assessment of information available on methods of swine carcass disposal under routine and catastrophic conditions. The authors have focused on efficiency and effectiveness of available methods as well as potential animal health and environmental protection considerations. The paper addresses the four predominant methods of mortality disposal in commercial swine production–burial, incineration, rendering, and composting–and various alternative and nontraditional methods and technologies.
