What is the term for the edge of any container that holds sterile supplies?

The term for the edge of any container that holds sterile supplies refers specifically to the area where sterility is compromised if contact occurs. This area is commonly recognized as unsterile. When handling sterile supplies, it's essential to understand that the edges are not considered part of the sterile field. They can become contaminated through touch, exposure to non-sterile surfaces, or the environment.

For maintaining sterility, only the contents inside the container are regarded as sterile, while the edges and any areas not designed to be sterile remain unsterile. By being aware of this distinction, surgical assistants can help prevent infection risks and ensure that procedures are performed safely. Thus, recognizing "unsterile" as the correct term to describe the edges of containers holding sterile supplies underscores the importance of maintaining a sterile environment in surgical settings.
