Natasha's Law and Food Trucks: Mobile Catering Compliance Guide
Food trucks and mobile caterers pre-packing items before service must comply with Natasha's Law. This guide covers what mobile food businesses need to do.
Food trucks and mobile catering units face a specific compliance question: does Natasha's Law apply to food made in the truck and handed directly to the customer, or only to pre-packed items?
The Key Distinction: PPDS vs Non-Prepacked
If a customer orders a burger and you make it fresh, placing it in a box and handing it over — that is non-prepacked food. Under UK law, you still need to be able to provide allergen information for non-prepacked food on request, but Natasha's Law labelling requirements do not apply.
However, if you pre-make and seal items before customers arrive — wraps, sandwiches, pastries, or snack pots prepared at a central kitchen and transported ready-packaged — those items are PPDS food and require full Natasha's Law compliant labels.
Common Food Truck PPDS Items
- Pre-made wraps or burritos prepared before the event
- Packaged snacks or sides made off-site
- Pre-portioned desserts sealed in cups or boxes
- Grab-and-go items in a chiller unit
Labelling on the Road
Creating compliant labels for mobile operations requires a reliable system that travels with you. Options include:
- Label printer loaded with standardised templates for each product
- Pre-printed labels with blank allergen fields completed before each service
- QR code labels linking to a digital allergen page — though physical allergen emphasis is still required on the packaging itself
Events and Festivals
At events where pre-made items are sold, enforcement inspections do happen. Local authority food safety officers attend food festivals and markets. Non-compliant labelling can result in food being removed from sale.
Understanding What Counts as Sealed Packaging
The question of what constitutes sealed packaging trips up many mobile caterers. A wrap placed in a paper bag that a customer could open and reseal does not qualify as PPDS packaging. However, a wrap placed in a sealed pouch or a container with a tamper-evident sticker applied before the customer interacts with it does bring that item into PPDS territory. The determining factor is whether the food is packaged and sealed before it is presented for sale, not simply whether it is in a container.
This distinction matters particularly for food trucks that prepare a morning batch of items at home or at a rented commercial kitchen, then transport them to a market pitch. Even if you intend to hand-sell those items individually, the moment they arrive at the pitch pre-packaged and ready to purchase without further preparation, they are PPDS. Courts and enforcement officers apply this definition consistently, and lack of awareness is not considered a mitigating factor during inspections.
If you are unsure whether a specific product qualifies, the safest practical approach is to treat it as PPDS and label accordingly. Applying a compliant label to food that technically did not require one causes no harm. Failing to label food that did require it can result in enforcement action, fines, and reputational damage that no market pitch income can offset.
Managing Multiple Products Across Different Pitches
Food truck operators who attend multiple events each week often carry a varied product range, and keeping allergen labelling consistent across that range introduces real operational complexity. A burger truck that also sells pre-made loaded fries in sealed trays, bottled sauces, and packaged brownie slices must maintain accurate labelling for each individual product, not just a general allergen notice for the whole stall. Each PPDS item needs its own label carrying the product name, full ingredients list, and the 14 major allergens emphasised — typically in bold — where present.
The most practical solution for multi-product operators is building a product library in a digital system, where each item has its allergen data stored and linked to a label template. When a recipe changes — even slightly, such as switching to a different brand of mayonnaise — the label must be updated before that batch goes out. Many operators underestimate how frequently supplier ingredient changes affect their allergen declarations, particularly for sauces, seasonings, and processed ingredients that contain compound ingredients listed further down the supply chain.
Keeping a printed or digital product folder at the pitch is also advisable. If a food safety officer asks to verify your allergen information for a specific product, being able to produce a complete ingredient breakdown quickly and confidently demonstrates due diligence. Officers generally respond well to operators who have clearly structured systems, even if minor administrative gaps exist, compared to those who cannot produce any documentation at all.
Allergen Information for Non-Prepacked Items at the Truck
Even when all your food truck items are made fresh to order and none of them qualify as PPDS, you still carry legal obligations under the Food Information Regulations. You must be able to provide accurate allergen information for each dish you serve, across all 14 major allergens, either verbally or in writing — and your staff must be trained to give that information correctly. A verbal system that relies entirely on the operator's memory is a compliance risk, particularly at busy events where communication is rushed or noisy.
The most reliable approach is a written allergen matrix displayed at the point of sale, or available for customers to consult. This can be a laminated card, a chalkboard, or a printed sheet in a protective sleeve. The format matters less than the accuracy and accessibility of the information. Customers with allergies need to be able to get clear answers quickly, and if your front-of-counter staff cannot provide that information confidently, it creates a legal and ethical gap that no amount of goodwill will close after an allergic reaction occurs.
If you sell through a Shopify store or take pre-orders online ahead of events, your online menu also needs to carry allergen information. The requirement to inform customers applies across every channel through which food is sold or described. Allergen Matrix makes it straightforward to display a clean, accurate allergen table on your Shopify storefront, so customers checking your menu before arriving at your pitch can see exactly what each dish contains.
Updating Labels When Recipes or Suppliers Change
One of the less visible compliance risks for food truck operators is the supplier change problem. When you switch from one brand of tortilla to another, or start using a different chilli sauce from a wholesale supplier, the ingredient list and allergen profile of your finished product may change without any obvious visual difference to the food itself. If your labels have not been updated to reflect that change, you are potentially providing inaccurate allergen information — which is a serious breach of food labelling law, regardless of intent.
Building a review process into your procurement habits is the practical answer. Each time you take delivery of a new product or substitute an ingredient, cross-check the new product's allergen information against your existing recipe records. If anything has changed — even if a previously declared allergen has been removed — update your labels before using the new ingredient in a batch that goes out labelled. This is particularly important for allergens like gluten, milk, and sesame, where suppliers may change manufacturing sites and cross-contamination risks shift accordingly.
Keeping dated records of your ingredient versions and label updates also protects you legally. If a complaint or enforcement query arises about a product sold three months ago, being able to show which version of a label was in use at that time, and what ingredient data underpinned it, demonstrates that you operated with reasonable care. Many food truck operators do not think about documentation until after a problem arises — building that habit early is significantly easier and cheaper than reconstructing records retrospectively.
Training Staff and Volunteers on Allergen Protocols
Food trucks at festivals and events frequently rely on casual staff, friends, or volunteers to help manage busy periods. These individuals may have no food safety background and no understanding of allergen law. As the registered food business operator, you remain legally responsible for every piece of allergen information communicated at your stall, whether you delivered it personally or a helper did on your behalf. Training those individuals before they begin serving is not optional — it is a direct requirement of due diligence.
A short pre-service briefing covering the 14 major allergens, which products at your stall contain which allergens, and how to handle allergen queries from customers takes no more than ten minutes and substantially reduces risk. Helpers should know never to guess or approximate when answering an allergen question, and should always refer the customer to the operator or to written information if uncertain. That single instruction — do not guess, point to the written information — prevents the majority of miscommunication incidents that lead to complaints or harm.
It is also worth having a clear protocol for what to do when a customer declares a severe allergy. This might include confirming whether cross-contamination risks exist at your prep station, advising the customer if you cannot guarantee a safe environment, and knowing when to decline a sale rather than risk a serious allergic reaction. These decisions are uncomfortable in a busy service environment, but having thought them through in advance means your staff can respond calmly and appropriately when it matters.
