Are all cleaning supplies inside the hood required to be sterile according to USP 797?

The correct understanding regarding cleaning supplies inside the hood, according to USP 797, is that not all cleaning supplies need to be sterile; rather, they must be appropriate for maintaining a clean and controlled environment. The purpose of cleaning supplies, such as detergents and disinfectants, is to reduce microbial contamination and ensure a sterile area for compounding.

While it is critical that the working area is maintained in a clean and sterile condition, not all items placed inside the hood are required to be sterile themselves. Supplies like gloves, wipes, and cleaning agents need to be effective in cleaning but do not necessarily have to be sterile. The focus is on maintaining a sterile environment to protect the compounded preparations, rather than the sterility of the cleaning agents themselves.

This understanding clarifies that the requirements are not as strict for all items in the hood, allowing for effective cleaning and sanitization without necessitating sterility for every object involved in the process.
