Mobile Food Unit Operation Guide 34-65 Rev 04/22
Class IV mobile food units may use one cooking unit, such as a BBQ or pizza
oven that is not integral to the unit. The cooking unit may not be a flat top grill,
griddle, vertical rotating spit, wok, steamtable, stovetop, oven, or similar
cooking device. The cooking unit must be able to move with the unit.
A Class IV mobile food unit may use a cooking unit when:
• It is in close proximity to the mobile food unit
• It is used only for cooking. Processing, portioning, preparation, or assembly
of food must be conducted from inside the mobile food unit
• A handwashing system must be provided adjacent to the cooking unit.
Operators may provide seating for customers if restrooms are readily accessible within
500 feet of the mobile food unit (6-402.11). The restroom must have a handwashing
facility that provides hot and cold running water, soap, and paper towels or air dryer.
When seating is provided, mobile food units must provide a garbage container for
customers.
Shelves or tables that are integral to the unit may be used to display non-potentially
hazardous condiments and customer single-use articles such as napkins and plastic
utensils. Mobile food units may display commercially packaged, non-potentially
hazardous food items, such as cans of soda or bags of chips, off the unit if they are
limited to what might be sold during a typical meal period.
Auxiliary storage shall be limited to an amount that can be used in a
day's operation and stored in such a manner as to prevent contamination or
infestation (water-tight covered containers). At the end of the day, items must
be placed in the unit or a licensed warehouse. No self-service, assembly or
preparation activities may occur from the auxiliary storage container.
Refrigerators and freezers may not be placed outside the unit and must be in the
unit or in a licensed warehouse. Handling of unpackaged foods, dishwashing
and ice making are prohibited in a warehouse.
Mobile Food Units Operating at Temporary Events
Events include fairs, carnivals, circuses, festivals, concerts, or any other temporary public gathering.
As a licensed mobile food unit, you may operate as a single-event temporary restaurant as specified
under ORS 624.650. If you are operating at a temporary event that you may utilize off-unit tables
and display areas for non-potentially hazardous foods and dispensed beverages, condiments, and
single-service articles such as napkins and utensils. However, the off-unit tables and display areas
allowed under this rule may not be used to conduct activities such as food preparation, assembly,
or cooking. In addition, the display or dispensing of potentially hazardous foods is not allowed.
Mobile food units that place equipment or conduct operations outside the unit that are beyond
those allowed in this rule must obtain a single-event temporary restaurant license from the county
where the event will be held.
