What is the purpose of decontamination?

• A. Growth of beneficial bacteria
• B. Removal of harmful microorganisms
• C. Storage of sterile equipment
• D. Packaging of tools for transport

Answer: (B)

Decontamination is about making instruments and surfaces safe by removing or inactivating microorganisms that could cause infection. The aim is to reduce the microbial load to levels that won’t transmit disease to patients or staff. In practice this means cleaning to remove organic debris, then applying disinfection or sterilization to kill or destroy remaining microbes, with the level of treatment chosen based on how the item will be used. It isn’t about promoting bacterial growth, nor is it about storing sterile items or packaging tools for transport—the core goal is to minimize the risk of infection by eliminating harmful microorganisms.
