You SHOULD follow the same food safety protocol for enforcement officers as any visitor (visitor sign in sheet, provide protection equipment, read rules… whatever you do to all visitors). Most of the times they will be polite enough to agreed and follow your hygiene rules…. Especially because they are there for that, to see if you have rues and follow them..
BUT with that said, they are ENFORCEMENT officers, so the actual answer to your questions of what they can do and not, you must check your local regulations and see how much authority they have.. All countries states and regulators would be different.
Finally, being ENFORCEMENT officers, there is always a chance of authority abuse… (As Snookie said, if they have guns…) In my personal case an Inspector from the HEALT DEPARTMENT OF COLORADO, didn’t want to sign the visitor logs or agreed to our rules, with the excuse that he “has to do anything he has to do to inspect the plant”… In that case, because of local regulations we would have been able to DENY the entry… but that would just put is in a black list with the department of health, so we just documented the situation and let him in.. (ny the way, he followed the rules, just didn't want to sign)
Bottom line, my advice would be ask them to follow the rules, but don’t push it.. They are the enforcers, not you.. If they do something wrong, or something that can contaminate the product, follow your FS protocols and document it.
