Fatalities involving these feed mixers may occur when operators become trapped in the augers or, less frequently, are crushed by moving wagons. Death can occur very rapidly because of dismemberment, multiple lesions, or crushing. The aim of this review is to focus on the diagnostic evaluations that need to be performed to confirm that the death was accidental and to exclude a hypothesis of murder or suicide. Forensic investigations in such cases must involve the detailed analysis of the death scene and the mechanical characteristics of the machinery with an accurate postmortem and toxicological examination.
