What term describes material contaminated with pathogens capable of transmitting diseases and requiring specialized handling to prevent infection?

• A. DDT
• B. Infectious/biohazardous waste
• C. Centers for Disease Control and Prevention (CDC)
• D. National Institutes of Health (NIH)

Answer: (B)

Material contaminated with pathogens that can transmit disease is called infectious/biohazardous waste. This term captures both the contamination and the need for specialized handling to prevent infection. Such waste includes items like used sharps, cultures, and clinical specimens, which must be kept separate from regular trash, placed in labeled, leak-proof, puncture-resistant containers, and disposed of through approved biohazard waste streams. It’s treated (for example, by autoclaving or chemical disinfection) to neutralize the pathogens before final disposal. This explains why the term is the best choice: it specifically describes the hazardous nature of the material and the precautions required. The other options don’t describe waste material—one is a pesticide, and the others are organizations—so they don’t fit this concept.
