Warehouse Hygiene Requirements for Large Companies

Hi,

Our factory process of food products and we have some dairy products (finished goods) that are stored in our warehouse. The product in this case is a dairy product and by spec it is to be stored at ambient temperature. Recently we have a potential customer from a MNC company planning to do supplier audit at our site. Basically the factory area are all covered, and we have our regular cleaning and pest control procedures for the warehouse. Just wondering if there is any specific requirement for the large company on the warehouse storage condition? Appreciate if someone can share me the requirement so we can have some preparation to be done before the visit.

Thank you. 

What regulations are you under - country, GFSI scheme. These matter more than the size of the facility.
