The term "biohazard" specifically refers to biological substances that pose a threat to the health of living organisms, particularly humans. This includes pathogens such as bacteria, viruses, fungi, and other microbes that may lead to diseases or infections. Biohazards can arise from various sources, including medical waste, contaminated surfaces, or even certain animals, and they require careful handling and disposal to minimize risks to health and the environment.

The correct understanding of biohazards is crucial in fields such as healthcare, laboratory work, waste management, and environmental protection, where ensuring safety is paramount. Recognizing biohazards enables professionals to implement appropriate containment, exposure controls, and emergency response practices to mitigate potential health risks.

The other options do not encapsulate the definition of a biohazard. Non-toxic plants and healthy food products do not pose threats to living organisms, while chemicals used for cleaning fall into different categories, such as hazardous materials or chemical hazards, but are not classified as biohazards since they do not originate from biological sources.
