Background: Workers can be injured by animals such as mammals and insects. Previous studies found that most animal-related occupational fatalities were caused by horses and cattle. We analyzed characteristics of recent nonfatal severe animal-related injuries in US workers.
Methods: The severe injury reports (SIR) database, collected by the Occupational Safety and Health Administration, contains employer self-reports of inpatient hospitalizations and amputations. We used 2015-2021 SIR data to assess properties of animal-related injuries, including the type of animal involved, the nature of the injury, and the industry of the employer. Industry-specific incidence rates were calculated.
Results: We identified 788 severe animal-related injuries during the 7-year study period. Mammals caused over half of these injuries (476; 60.4%), followed by insects, arachnids, and mites (183; 23.2%) and reptiles (127; 16.1%). Two-thirds (529; 67.1%) of animal-related injuries were traumatic, while 211 (28.0%) injuries were due to poisoning or allergic reaction. The highest observed incidence was in livestock merchant wholesalers (59.6 severe injuries per 100,000 workers per year); injuries in this industry were often due to cattle. Mail delivery and landscape architecture, two industries in which animal contact is atypical, were also among the 10 industries with the highest incidence.
Conclusions: Workers in many industries experienced severe injuries due to animals. Among workers whose job involves animal contact, cattle workers appear to be at highest risk. Outdoor workers in some industries require protection from bites of dogs, snakes, and insects.
