That organizer isn't doing right by the cooks. If I ran an event where an HD inspector appeared I would personally sit chaperone them and run interference for the cook teams from 11:30-2:00.
Of course the proper thing to do is to prevent this from happening in the first place. There is absolutely no reason for a health inspector to be in a comp team's site unless that team is serving food to the public. Judges sign a waiver, they don't count as "public".
