A Comparative Investigation of Equine-Related and Bovine-Related Human Fatalities in Oklahoma.

This study examined 71 cases, where 45 cases were equine-related and 26 were bovine-related. Data for this study were collected by examining cases between 2000 and 2022 from the Oklahoma Office of the Chief Medical Examiner database.A majority of the equine-related fatality cases involved males aged 0 to 18 and 60 to 69 years, with sustained injuries of the head, neck, and thoracic regions while being mounted. These injuries were most often inflicted by being kicked or resulted from blunt force of impact. A majority of the bovine-related fatality cases involved males aged 60 to 79 years, with sustained injuries of the head, neck, and thoracic regions while being unmounted. These injuries were most often inflicted by being butted, trampled, or resulted from blunt force of impact. Of the total cases, approximately 42% of the causes of death were blunt force trauma of the head/neck and nearly 34% were multiple blunt force injuries. Only 3 mechanisms of death were discussed.There are distinct similarities in the most prominent gender, cause of sustained injury, and location of injury between equine- and bovine-related fatalities in Oklahoma. This study lends significant support to the need for increased awareness of safe handling practices and safety precaution education for both equine and bovine activities.
