Which term describes living organisms that can pose health risks in a work environment?

The term that best describes living organisms that can pose health risks in a work environment is "Biological Agents." This encompasses a range of living entities, including bacteria, viruses, fungi, and other microorganisms that can potentially lead to illness or adverse health effects. Biological agents are a significant concern in occupational health and safety because they can be transmitted through various means, such as air, contact with contaminated surfaces, or through food and water.

While terms like pathogens and microorganisms refer specifically to agents that can cause disease, "biological agents" is broader and includes various living organisms that may affect health, extending beyond just those that are pathogenic. Toxic substances, on the other hand, generally refer to non-living chemicals or materials that can cause harm through exposure, thereby excluding the biological aspect. Thus, "Biological Agents" comprehensively covers the range of living organisms that pose health risks in occupational settings.
