Making a third reply to also say that in terms of what needs to be sterile and what needs to be disinfected, the only things that are held to the standard of sterile are things that are involved when something is entering the body, like for surgery, needles going inside you, open wounds etc.

For most everything else disinfected or even just clean to the naked eye is considered up to standard, the big issue here was that they were apparently disinfecting surgical gowns and not sterilizing them or treating them as single use.
