Assuming you are an USDA FSIS inspected facility, I agree with Jpredmore. Your sanitation-related documents should be initialed at the date/time the activity was conducted. Master Sanitation Schedule (MSS) activities - cleaning of non-product contact surfaces - under USDA are typcially done on a less than daily basis, as jpredmore mentioned. MSS documentation can be done by the person conducting the cleaning, but BRC auditors at my plants have also expected a periodic verification inspection.
However, I do beg to disagree with jaySTARR. Operational SSOP monitoring under USDA is to be conducted at the frequency you determine and can support - there is no regulatory requirement that I am aware of for 2x/day monitoring.
All of this is, of course, predicated on what you have written into your various sanitation programs...
