HACCP for Food Trucks and Mobile Food Businesses

A mobile kitchen is not simply a small restaurant. Every move can change the water connection, electrical load, ambient temperature, waste arrangements and distance from refrigerated backup. Your HACCP-based system must describe the operation that actually arrives on site—not an idealised fixed kitchen.

Map the mobile process before choosing controls

Draw a process flow from the approved base or supplier through loading, transport, site setup, preparation, cooking, holding, service, return transport and disposal. Include potable-water filling, wastewater emptying, fuel or battery changes, and food returned to base. Confirm the flow during a real service because queues, cramped benches and cable or hose routes often create hazards that a desk exercise misses.

For each step, assess biological hazards such as pathogen growth and cross-contamination, chemical hazards such as cleaning-fluid or fuel contamination, physical hazards from damaged equipment or the outdoor environment, and allergens. Decide whether each hazard is controlled by prerequisites—cleaning, supplier approval, personal hygiene and pest control—or needs a measurable critical control point. See the step-by-step HACCP guide for the seven-principle method.

Mobile-operation controls

1. Potable water and handwashing

• Use a potable mains connection or clean, food-grade containers filled from an approved potable source. Record the source when it varies by site.
• Size the fresh-water supply for handwashing, food preparation, cleaning and the full service period. Keep a sealed reserve and define the minimum volume required to open.
• Protect filler caps and hoses from the ground, wastewater connections and vehicle chemicals. Use dedicated, labelled hoses; sanitise tanks and hoses to a written schedule.
• Provide an accessible handwash basin with running warm water where locally required, soap and hygienic drying. A bowl shared with utensil washing is not an adequate substitute.
• If water runs out, becomes contaminated or the pump fails, stop any activity that needs safe handwashing or water. Use only a pre-approved restricted menu if your authority permits it; otherwise close.

2. Limited refrigeration

Capacity, not merely set-point, is the constraint. Load only what the unit can keep within the legal or validated cold-holding limit, allow air to circulate, separate raw food from ready-to-eat food, and minimise door opening. Pre-chill the cabinet and product at base rather than expecting a small vehicle refrigerator to pull warm stock down safely.

Check and record product or simulated-product temperatures at loading, arrival, before service, during service and at close. Set limits from the law and official guidance that applies where you trade; do not copy a temperature from another country. Keep calibrated probe thermometers, sanitising wipes and an insulated backup box with sufficient conditioned ice packs. If capacity is exceeded, reduce the menu or replenish from an approved refrigerated base—never store overflow on the floor or at ambient temperature.

3. Power or fuel failure

Write a failure plan that staff can follow without calling the owner. It should identify which equipment is on each circuit, the safe electrical or generator load, backup refrigeration or insulated storage, who may restart gas appliances, and the food-disposition rule.

1. Record the failure time and keep refrigerator and freezer doors closed.
2. Stop preparation and sales when cooking, hot holding, extraction, lighting, handwashing or safe payment-area separation cannot be maintained.
3. Check food temperatures and time out of control; move stock to verified backup only if this can be done safely.
4. Quarantine affected food. Keep it only when your documented time/temperature assessment demonstrates compliance; otherwise discard it and record the corrective action.
5. Before reopening, restore water, lighting, ventilation and temperature control, clean any contaminated surfaces, and verify equipment readings.

4. Transport to and from the pitch

Treat transport as a food-handling step. Use clean, lidded, food-grade containers; secure loads against movement; segregate raw, ready-to-eat and allergen-controlled items; and keep food away from gas cylinders, fuels, chemicals and personal belongings. Verify vehicle or container temperature at dispatch and arrival. Maintain traceability for every batch loaded, sold, returned or wasted.

Define whether leftovers may return to base. Food with an uncertain temperature history, food exposed during service, or food that cannot be traced should not be carried forward to another event. A return-to-base log should state the item, quantity, time, temperature, decision and person responsible.

5. Temporary-site setup

Use a pre-opening site check before food is exposed:

• park on stable, clean ground away from drains, standing water, dust, refuse, animals and vehicle exhaust;
• secure the vehicle, trailer, canopy, serving hatch, LPG cylinders, cables and potable-water hoses;
• confirm safe power, lighting, ventilation and fire controls, with cables and hoses protected from customers and traffic;
• install handwashing before preparation starts and keep the basin unobstructed;
• create a clean flow from storage to preparation to cooking to service, with raw-food tools and dirty returns kept out of ready-to-eat areas;
• check pest exclusion, food covers, thermometer function, sanitiser concentration and allergen information; and
• confirm toilets and staff welfare arrangements are available and acceptable to the relevant authority.

6. Waste and wastewater

Provide lidded, leakproof bins with enough capacity for the expected trade and keep them away from food, clean equipment and fresh-water storage. Remove refuse before it overflows; do not place bags on the ground where they attract pests or contaminate the pitch. Store used cooking oil in a sealed, labelled container.

Capture wastewater in a closed, labelled tank sized for the service. Monitor its level and empty it only at an authorised disposal point—never onto the street, soil or a surface-water drain. A full or leaking wastewater tank is a stop-service condition if hygienic operation cannot continue.

7. Weather and the outdoor environment

Set weather triggers in advance. Heat and direct sun increase refrigeration load; wind carries dust and can make flames or canopies unsafe; rain can contaminate open food and electrical connections; freezing weather can stop water flow. Use side screens and food covers where appropriate, shade refrigeration and cold displays without blocking ventilation, and increase temperature checks during extreme heat.

Pause service when wind exceeds the equipment or canopy rating, flooding or runoff reaches the pitch, pests or airborne debris cannot be controlled, the water system freezes, or electrical equipment becomes unsafe. After an incident, discard contaminated food, inspect packaging and equipment, clean and disinfect, and document the reopening check.

8. Registration, permits and moving between authorities

Registration and permit rules are local. Before trading, contact the food authority responsible for the business or approved base and the authority responsible for every pitch. Ask about food-business registration or notification deadlines, mobile-unit approval where applicable, street-trading or market consent, event notification, waste and wastewater rules, fire/LPG certification, and whether a change of base, vehicle, menu or trading area must be reported.

Do not assume registration in one municipality automatically authorises trading in another. Keep confirmations, inspection details and organiser requirements in the unit. In the EU, Regulation (EC) No 852/2004 provides the hygiene framework, but competent authorities administer registration and national or local rules. In the UK, registration and street-trading arrangements likewise depend on the relevant nation and local authority. Verify current requirements directly rather than relying on a generic checklist.

A practical opening and closing record

A single mobile-service record can capture the controls most likely to change from pitch to pitch:

• date, vehicle or stall, location, authority or organiser, supervisor and menu;
• fresh-water source, tank sanitation status, opening volume and wastewater capacity;
• dispatch and arrival temperatures, refrigerator capacity check and probe verification;
• power source, pre-use equipment checks and backup arrangements;
• site, weather, handwashing, waste, pest and allergen-information checks;
• cooking, reheating, hot/cold holding and any cooling monitoring required by the plan;
• failures, corrective action, quarantined or discarded food and downtime; and
• closing stock disposition, waste transfer, wastewater disposal, cleaning and return-to-base temperatures.

Use the opening and closing checklist, temperature log and traceability log as starting points, then adapt them to the unit and local rules.

Verify the plan under real service conditions

Review records after the first service at every materially different site and whenever the menu, equipment, vehicle, base, water source or power supply changes. Test the failure plan, not just the normal process: simulate loss of refrigeration, estimate how long potable water lasts at peak trade, and confirm staff know the stop-service rules.

The strongest mobile HACCP plan is short enough to use in a rush but specific enough to answer three questions: what changed at this site, how was it checked, and what did the team do when control was lost?
