Allergen management is one of the most important food safety responsibilities for a UK food truck. Mobile catering businesses may have small kitchens, frequently changing menus and intense periods of service, but they are still responsible for providing customers with accurate information about allergens.
For food truck operators, allergen labelling compliance involves more than adding a few symbols to a menu. The rules that apply depend partly on how the food is prepared, packaged and sold. A sandwich packaged before a customer orders it, for example, can be subject to different requirements from a burger prepared after an order is placed.
Understanding these distinctions is essential for operating a compliant and safe mobile catering business.
What Are the 14 Allergens UK Food Businesses Must Declare?
UK food businesses need to provide information when food contains any of the 14 allergens that must be declared under food information rules.
These are:
- celery;
- cereals containing gluten, including wheat, rye, barley and oats;
- crustaceans;
- eggs;
- fish;
- lupin;
- milk;
- molluscs;
- mustard;
- nuts;
- peanuts;
- sesame;
- soya;
- sulphur dioxide and sulphites above the applicable threshold.
Food truck operators should know which of these allergens are present in every dish they sell.
The information must take account of the complete recipe rather than only its most obvious ingredients. Sauces, marinades, spice mixes, bread, dressings and garnishes can all introduce allergens that may not be immediately apparent.
Do Food Trucks Have to Display Allergen Information?
Food trucks must make allergen information available to customers, but the way that information needs to be provided depends on how the food is sold.
This distinction is important because a food truck can potentially sell several categories of food during the same service.
A burger cooked and assembled after the customer orders it is not treated in exactly the same way as a packaged sandwich prepared in advance and placed on display for customers to select.
Operators should therefore assess individual products rather than adopting one labelling method for the entire business without considering how each item is supplied.
Allergen Information for Non-Prepacked Food
Much of the food sold by food trucks is non-prepacked food. Typical examples include tacos assembled to order, freshly prepared burgers, portions of chips, pizzas and meals served directly from the cooking area.
For non-prepacked food, businesses must provide information about the presence of the relevant 14 allergens.
Depending on the applicable requirements, allergen information can be communicated in different ways. If customers are expected to ask staff for the information, there should be a clear indication that this information is available.
However, relying on verbal communication requires excellent staff training.
An employee should never guess whether a product contains an allergen. There should be a reliable source of information that staff can consult immediately.
What Is Natasha’s Law?
Natasha’s Law is the commonly used name for requirements introduced for food that is prepacked for direct sale (PPDS).
The rules came into force in October 2021 and significantly changed labelling requirements for businesses selling PPDS food.
Where a product qualifies as PPDS, its packaging must carry a label containing the name of the food and a full ingredients list, with the relevant allergens emphasised within that list.
This can be particularly relevant to food trucks that prepare and package products before customers select or order them.
The crucial point is that operators should determine whether a particular item actually meets the definition of PPDS rather than assuming Natasha’s Law applies to everything sold from a food truck.
What Is Prepacked for Direct Sale Food?
PPDS food is broadly food that is packaged at the same place from which it is offered to consumers and is packaged before it is ordered or selected by the customer, provided the relevant legal conditions are met.
For a food truck, possible examples could include sandwiches, wraps, salads, cakes or desserts that are prepared and packaged in advance and then offered for sale from the truck.
By contrast, if a customer orders a sandwich and staff then make and package it specifically for that customer, the product would not normally fall into the same PPDS category simply because it is handed over in packaging.
This distinction has practical consequences for labelling.
Food truck operators selling grab-and-go products should therefore examine their preparation and sales process carefully.
How Should Allergens Be Shown on PPDS Labels?
When a food product falls within PPDS rules, the label needs to include the name of the food and a complete ingredients list.
Within the ingredients list, any of the 14 regulated allergens present must be emphasised so that they stand out clearly.
This can be achieved using methods such as bold type, although other forms of emphasis may be possible where they clearly distinguish the allergen from the surrounding ingredients.
For example, if a sauce contains milk or a bun contains wheat, those allergens need to be identified appropriately within the ingredients list.
Simply placing a generic statement such as “contains allergens” on a PPDS product would not replace the required ingredients information.
Creating an Allergen Matrix for a Food Truck
An allergen matrix can be one of the most useful operational tools for a food truck.
The matrix lists menu items against the 14 regulated allergens, allowing staff to identify quickly which dishes contain each allergen.
For example, the rows could contain menu items such as:
| Menu item | Gluten | Eggs | Milk | Peanuts | Sesame | Soya |
|---|---|---|---|---|---|---|
| Classic burger | Yes | Check recipe | Yes | No | Check bun | Check sauce |
| Vegan taco | Check | No | No | Check | Check | Check |
| Loaded fries | No* | Check toppings | Yes | No | No | Check sauce |
The information must be based on the actual ingredients and preparation methods used by the individual business. A generic allergen matrix downloaded from another restaurant should never be copied without verification.
The matrix also needs to be updated whenever ingredients, recipes or suppliers change.
Ingredient Changes and Allergen Compliance
Food truck menus can change quickly.
A supplier may run out of a particular burger bun, sauce or vegan product immediately before a festival. The operator might then purchase an alternative from another supplier.
From an allergen perspective, this substitution cannot be treated as insignificant.
Two apparently identical ingredients can have different allergen profiles.
If a normal ingredient is replaced, the new product label or specification should be checked and the business’s allergen information updated where necessary.
Staff working that service also need to know about the change.
This is one reason why maintaining accurate supplier and ingredient information is an essential part of allergen management.
Preventing Allergen Cross-Contamination
Providing correct information about ingredients is only part of allergen safety.
Food trucks also need to consider cross-contamination or cross-contact during preparation and service.
This can be particularly challenging inside a small mobile kitchen where multiple dishes are prepared within a few square metres.
Shared fryers, grills, utensils, chopping boards, preparation surfaces and storage containers can all create risks.
For example, a food item may not contain an allergen as an intentional ingredient but could come into contact with it through shared cooking equipment.
Businesses should understand these risks before making claims to customers about whether a dish is suitable for someone with an allergy.
Precautionary Allergen Labelling
Statements such as “may contain” should not be used automatically on every food item simply as a precaution against all possible risks.
Precautionary allergen information should reflect a genuine risk that cannot be sufficiently controlled after appropriate assessment and management.
Using broad warnings unnecessarily can make it more difficult for people with allergies to understand what they can safely eat.
Food truck operators should therefore identify how allergens move through their particular preparation environment and establish practical controls.
Allergen Training for Food Truck Staff
Staff are a critical part of allergen compliance.
Every employee who takes orders or handles food should understand the business’s allergen procedures and know where accurate information can be found.
Training should cover areas such as:
- recognising the 14 regulated allergens;
- understanding the food truck’s allergen matrix;
- checking ingredients rather than guessing;
- communicating clearly with customers;
- preventing cross-contact;
- dealing with recipe or ingredient changes;
- understanding the importance of allergy requests.
A particularly dangerous situation occurs when a staff member assumes that they remember a recipe and gives an immediate answer without checking.
A better procedure is to verify the information every time there is uncertainty.
Taking Orders from Customers with Food Allergies
Food truck staff should have a clear procedure for handling allergy-related orders.
When a customer identifies an allergy, the information should be communicated to the person preparing the food. Staff should then check the relevant ingredients and consider whether cross-contact can be adequately controlled.
Communication is particularly important during busy service periods.
At a festival, employees may be handling hundreds of orders in a short period. The business should therefore have a system that makes an allergy order clearly distinguishable from an ordinary order.
Employees should also understand the limits of what the business can safely provide.
Making an unsupported promise that a dish is completely free from a particular allergen can create serious risks.
Allergen Information for Online and Telephone Orders
Some food trucks take orders before customers reach the vehicle. This may happen through a website, mobile ordering platform, delivery service or telephone order.
When food is sold through distance selling, allergen information needs to be considered at more than one stage of the transaction.
Businesses need to ensure customers can access the required allergen information before completing their purchase and that the information is also available when the food is delivered.
Food truck owners introducing online ordering should therefore include allergen compliance in the design of the ordering process rather than treating the website or app simply as another payment channel.
Vegan and Vegetarian Food Trucks and Allergens
Vegan or vegetarian food trucks are not automatically low-risk environments for allergens.
Plant-based dishes frequently contain ingredients such as soya, sesame, nuts, peanuts, gluten and mustard.
A vegan burger, for example, could contain soya in the patty, wheat in the bun, sesame seeds on top and mustard in the sauce.
Businesses also need to distinguish between dietary preferences and food allergies.
A customer asking whether something is vegan is asking a different question from someone who has a severe milk allergy.
Food truck staff should therefore avoid treating “vegan”, “dairy-free” and “safe for someone with a milk allergy” as automatically interchangeable statements.
Allergen Information at Festivals and Street Food Markets
Festivals create particular challenges because menus may be shortened, suppliers can change and temporary staff may be recruited for only a few days.
However, the requirement to provide accurate allergen information does not disappear because an event is busy or temporary.
Before attending a festival, operators should check that allergen documentation matches the exact menu being served at that event.
Temporary workers should also receive appropriate allergen training before they begin taking orders.
Event organisers may request information about allergen procedures as part of their trader requirements, alongside food hygiene, insurance and safety documentation.
What Happens If a Food Truck Gets Allergen Labelling Wrong?
Incorrect allergen information can have consequences far more serious than an ordinary labelling mistake.
For a customer with a serious allergy, consuming even a small amount of the relevant allergen can potentially cause a severe reaction.
Food businesses can also face enforcement action where they fail to comply with applicable food information requirements.
Beyond the regulatory consequences, an allergen incident can cause substantial reputational damage to a food truck.
This is why allergen compliance should form part of the business’s everyday food safety management rather than being treated simply as a menu-design exercise.
Food Truck Allergen Compliance Checklist
Before beginning service, a UK food truck should be able to answer several basic questions:
- Do we know which of the 14 regulated allergens are present in every menu item?
- Are ingredient specifications current?
- Have we checked sauces, marinades, garnishes and other less obvious ingredients?
- Do any products qualify as PPDS?
- Are PPDS labels compliant where required?
- Is our allergen matrix up to date?
- Have staff been trained to answer allergy questions?
- Do we have procedures for preventing cross-contact?
- Do we review allergen information when suppliers or recipes change?
- Can customers obtain allergen information before purchasing through distance sales channels?
If the answer to any of these questions is uncertain, the procedure should be reviewed before relying on it during service.
Managing Allergens Safely on a UK Food Truck
Effective allergen labelling compliance for a food truck depends on connecting several parts of the business: recipes, supplier information, labelling, kitchen procedures, staff training and customer communication.
The compact nature of a food truck can make allergen management challenging, but it can also make procedures easier to standardise when the business is organised properly.
Operators should know exactly what goes into each dish, maintain current allergen information and establish a clear process for dealing with allergy requests.
Particular attention should be given to PPDS food and Natasha’s Law, because packaging food before it is selected or ordered can change the labelling requirements that apply.
Ultimately, the objective is not simply to have an allergen chart available somewhere inside the truck. A compliant system should allow every member of staff to provide reliable information and handle allergy-related orders safely, even during the busiest period of a festival or street food service.
