Question

The presence of blood or other potentially infectious materials on an item's surface, or visible debris or residues such as dust, hair and skin

Answer 1

Answer:

The term for this definition is contamination.

Explanation:

When an object or surface is contaminated, it means that there are certain pathogens, potentially infectious materials, or things that should not be there, and that can affect a procedure or someone's immune system. When something is contaminated, it should be decontaminated, removing all the risky things.
