Quick Scoop

Biohazard waste is any waste that may contain infectious material and could spread disease or contaminate people or the environment if not handled properly. It commonly includes sharps, blood-soaked items, lab cultures, tissues, and other contaminated materials.

What it includes

  • Sharps, such as needles, scalpels, and broken glass that may be contaminated.
    • [2][5]
  • Infectious materials, such as blood, body fluids, and cultures or stocks of microorganisms.
    • [5][1]
  • Pathological waste, such as tissues, organs, and body parts.
    • [2][5]
  • Contaminated items, such as gloves, gowns, tubes, petri dishes, and specimen containers.

Why it matters

Biohazard waste needs special handling because improper disposal can expose workers and the public to infection and can spread contamination. It is usually treated through methods like autoclaving, disinfection, or incineration before disposal.

Simple example

A used needle from a clinic, a blood-soaked bandage, or a lab dish with bacteria culture can all count as biohazard waste because they may carry infectious agents.

TL;DR: Biohazard waste is anything contaminated with potentially infectious biological material and must be disposed of safely.
