Biohazardous waste is defined as items that are

• A. Ordinary office paper
• B. Recyclable plastics
• C. Food waste
• D. Items contaminated with blood, body fluids, secretions, or excretions

Answer: (D)

Biohazardous waste involves items contaminated with blood or other potentially infectious materials. The best choice is the one that says items contaminated with blood, body fluids, secretions, or excretions. These substances can carry pathogens, so anything touched or soaked with them—like used tissues, bandages, gauze, or contaminated gloves—needs special disposal to prevent infection and exposure. Ordinary office paper, recyclable plastics, or regular food waste aren’t considered biohazardous unless they themselves are contaminated with such fluids. This distinction helps ensure proper safety precautions and regulatory disposal procedures.
