Food-safe delivery: what you need to know about transport and temperature
The food is ready, the order is complete, but things can still go wrong on the way to the venue. Temperature is the most underestimated risk factor in catering transport. Too warm, too long, or without the right storage and you deliver a problem instead of a meal. These are the basic rules you need to have in order.
The two zones you must not mix up
Food safety during transport comes down to two principles: keep cold things cold and hot things hot. That sounds simple, but in practice it goes wrong the moment you load both into the same vehicle without thinking about storage.
Cold dishes must stay below 7°C. Hot dishes remain safe above 60°C. Everything in between is the danger zone: the temperature range in which bacteria multiply fastest. The longer food sits in that zone, the greater the risk. In catering transport, time in that zone is your main measure.
How long is acceptable?
The rule of thumb under most food hygiene codes: food may spend a maximum of two hours in the danger zone, accumulated across the entire chain from production to serving. That sounds like plenty, but with on-site catering it adds up quickly. Preparation in the kitchen, loading, driving, unloading, setting up. Before you know it you're at an hour without anything having gone wrong.
Keep a timeline for every event. When is the food ready? When does the vehicle leave? When is service? Once those times are on paper, you can see straight away where the pressure points are.
What you need for safe transport
You don't need a professional refrigerated van to work food-safely, but you do need the right equipment:
- Insulated containers or thermal boxes. Not just for hot food, for cold too. A standard plastic tub loses its temperature quickly in a warm vehicle.
- Cool packs or heat pads. Cool packs for cold products, heat pads or gastronorm containers in an insulated bag for hot dishes.
- A thermometer. Check the temperature of your products before departure and on arrival. Don't guess, measure. A basic probe thermometer costs little and removes uncertainty.
- Separation of raw and prepared food. Make sure raw meat or fish can never come into contact with prepared products, including indirectly through leaking or moisture.
What to record for HACCP
If you work under the catering hygiene code (which is mandatory when you serve food outside your own kitchen), documentation is part of it. It doesn't have to be complicated. A simple log with the following details per job is usually enough:
- Date and event name
- Time of preparation and departure
- Temperature at departure and arrival
- Any deviations and what you did about them
During an inspection you show that you actively manage temperature control. That's the point of HACCP: not filling in forms, but demonstrably controlling risks.
What to do if the temperature is off
Sometimes things don't go to plan. The vehicle sits too long in the sun, there's traffic, the heat unit fails. What do you do?
Cold food that has risen above 7°C can still be served safely if the total time in the danger zone has been short (under two hours in total). If that limit has been exceeded, throw it out. That sounds harsh, but a case of food poisoning at your client's event will cost you far more than the price of the dishes. Make that call on-site, not afterwards.
Frequently asked questions
Do I need a refrigerated van for catering transport?
Not necessarily. Well-insulated thermal boxes with cool packs or heat pads are sufficient for most jobs, as long as journey times are short and you monitor temperatures. For longer distances or large volumes, a refrigerated van or cooled transport compartment becomes advisable.
What is the maximum temperature for cold dishes during transport?
Cold products must stay below 7°C. For sensitive items such as fish, deli meats and dairy, a stricter limit of 4°C applies. Use a thermometer to check, not your instinct.
Do I need a HACCP plan as a small caterer?
If you prepare and serve food to consumers, yes. The catering hygiene code describes a simplified HACCP system that is manageable for small businesses. You don't need an extensive written plan, but you must be able to show that you are controlling the risks.
How long can prepared food stand outside refrigeration at an event?
As a rule of thumb: a maximum of two hours in the danger zone (7–60°C) across the entire chain. On a buffet that stands for hours, that time adds up quickly. Work with small batches that you replenish, so not everything sits out too long at the same time.
What if I'm not sure whether a product is still safe?
Throw it out. The costs of food poisoning, in reputational damage, medical liability and lost clients, far outweigh the cost of the dishes. If in doubt, the answer is always to discard.
