9. CLEANLINESS AND SANITATION - All teams are expected to maintain their cook sites in an orderly and clean manner and to use good sanitary practices during the preparation, cooking, and judging process. The use of sanitary gloves is required at all times while handling food. Failure to use sanitary gloves may result in disqualification. Teams are responsible for cleanup of their site once the competition has ended. All federal, state and local food safety rules and regulations must be adhered to at all times.
The last line says a lot... I would find out what of the federal, state and local regulations they are going by. They vary on how they view the set up. Some may require a 3 compartment like sink set up, hand washing area and some may even require hot water. So if you know the comps you want to do, contact them and see what is required for their event....
