The information presented does not indicate or suggest a relative risk of exposure based on the location within the table nor provides any exposure information. Health risks associated with fatigue, working long hours, and other psychosocial disorders are not addressed.

The focus of this information is to provide guidance to understand the occupational health hazards from chemical substances, physical and biological agents, radiological, ergonomic, and environmental hazards from exposure to plants and animals. Potential occupational health exposures in this industry were contrived from the OSHA Integrated Management Information System database between 1984 to 2020. Additional information was obtained from the National Institute for Occupational Safety and Health (NIOSH) Health Hazard Evaluations performed by request of employee representatives and organizations from 1978 to 2020.
