HD rules are really state and county dependent. I have found that the closer you get to a big city the more onerous the inspection. I am in California so what I read about Iowa and other states sounds like a dream for us here in CA where I have had inspectors want to see the receipts for the product to check the date bought and want to know how it was stored between purchase (only allowed to purchas the day of the event) and cook. We are not a business friendly environment. A friend of mine was almost shut down because he had some open cold cuts in a separate cooler for his own lunch. OMG, what we have to put up with.
