Natasha’s Law: what your food labels need

If you pack food before a customer chooses it, that pack needs a label showing the name of the food and a full ingredients list, with any of the 14 allergens emphasised within that list. That is the whole requirement. Everything below is how to do it well.

What Natasha’s Law is

Natasha’s Law is the everyday name for the food labelling change that came into force on 1 October 2021 across the UK. It closed a gap: food packed on the premises where it was sold used to be exempt from carrying an ingredients list, which meant a customer with an allergy had no written information to read.

The law itself is short. Food that is prepacked for direct sale — PPDS — must carry the name of the food and a full ingredients list, with allergens emphasised inside that list.

Whether it applies to you

It applies to the food, not the business. A café can have three products that need labels and two that do not, on the same counter, on the same day. The test the FSA uses:

The definition, in the FSA’s words

“Prepacked for direct sale or PPDS is food that is packaged at the same place it is offered or sold to consumers and is in this packaging before it is ordered or selected.”

Two conditions, both of which have to be true:

  • It is in packaging — wrapped, boxed, bagged, or in a lidded pot. Food on an open tray or under a dome is not packaged.
  • It was packed before the customer chose it — the sandwiches made at 8am for the lunch rush, not the one built while the customer waits.

The FSA’s own examples of food that is PPDS include sandwiches and bakery items packed on site, boxed pizzas, rotisserie chicken, salad boxes, butcher’s products, and food served in schools, care homes and hospitals. Food that is not PPDS includes hot drinks made to order, unpackaged cakes in a glass display, pizza slices served on an open tray, and chips put into packaging at the moment of ordering.

Packing somewhere else and selling at a stall still counts. The FSA’s guidance for mobile sellers and market traders covers businesses that “package food yourself at a different location” — which is most home bakers who sell at markets.

What must be on the label

Three things. That is all PPDS itself requires.

WhatDetail
The name of the foodWhat a customer would call it. “Chocolate brownie”, not an internal product code.
A full ingredients listEvery ingredient, in descending order of weight at the time the product was made, with compound ingredients broken out in brackets.
Allergens emphasisedAny of the 14 allergens present must stand out from the rest of the list — every time they appear.

The label also has to be legible and visible. The FSA puts it plainly: a customer “should not need to open the packaging to access this information”.

Emphasising allergens

The guidance permits four methods: bold type, capital letters, contrasting colours or underlining. Any one of them satisfies the requirement.

In practice, bold capitals is the safest choice. It survives a monochrome thermal printer, a photocopy, a smudge, and a customer reading in poor light. Colour alone fails all four, and fails anyone who cannot easily distinguish it.

The rule people miss

Allergens must be emphasised every time they appear, not just on first mention. A salted caramel brownie has milk in the butter and milk again in the caramel’s cream and butter. All of them get emphasised.

More detail: how to emphasise allergens on a food label.

A worked example

A chocolate brownie. Four allergens, one of them inside a compound ingredient, one of them in an ingredient whose name does not mention it at all.

Ingredients label · 60 × 40 mmExample

Chocolate Brownie

Ingredients: Caster sugar, Butter (MILK), Free range EGGS, Dark chocolate (cocoa mass, sugar, cocoa butter, emulsifier: SOYA lecithin), WHEAT flour, Cocoa powder, Sea salt.

Example Bakery

Three things are happening there worth copying:

  • Butter is written as “Butter (MILK)”. The ingredient still has to be named — you cannot replace “butter” with “milk” — so the allergen is added to it.
  • The chocolate is broken open. Its own ingredients appear in brackets, and the soya inside it is emphasised there.
  • “Wheat flour” becomes “WHEAT flour”. Here the allergen is written in the name, so it is emphasised where it stands.

Four more worked examples, including a sandwich, which is almost entirely compound ingredients.

What it doesn’t require

A lot of confusion comes from mixing PPDS up with the rules for prepacked food — the sandwich in a supermarket chiller. Those need a net quantity, a date mark, and the food business operator’s name and address. PPDS does not require those.

Plenty of businesses add a date anyway, because it is useful for rotation, and some add their name because it is good practice and good marketing. That is a choice, not the law. And other rules can apply to a particular product regardless — so treat the three requirements as a floor, not a ceiling.

Five common mistakes

  1. Listing allergens instead of ingredients. “Contains: milk, wheat, egg” is not an ingredients list. The allergens have to be emphasised inside the full list.
  2. Flattening a compound ingredient. Writing “chocolate” and stopping. If the chocolate has its own ingredients, they belong in brackets after it.
  3. Emphasising only the first mention. Every occurrence.
  4. Copying an old label without re-checking. Suppliers reformulate quietly. A label is only as current as the last time somebody read the tub.
  5. Using a brand name. A customer cannot look up what is in your supplier’s product. Copy the declaration from the pack.

A checklist

Before a label goes on food:

  • The name of the food is one a customer would recognise
  • Every ingredient is listed, including the small ones
  • They run heaviest first
  • Compound ingredients show their own ingredients in brackets
  • Every one of the 14 allergens present is emphasised, everywhere it appears
  • The text is legible on the finished pack without opening it
  • The supplier declarations behind it have been read within living memory

Questions

When did Natasha’s Law come into force?
1 October 2021, across England, Wales, Scotland and Northern Ireland.
Does it apply to food I make to order?
Not as PPDS. If you put the food into its packaging after the customer orders it — chips bagged at the counter, a sandwich made to order — that is not prepacked for direct sale. You still have to provide allergen information, but it does not have to be a label on the pack.
Does it apply if I bake at home and sell at a market?
Yes, if you pack the food before someone chooses it. The FSA guidance for mobile sellers and market stalls is explicit that packing at a different location from where you sell is still covered.
Do I have to write ‘may contain nuts’?
No — precautionary allergen labelling is not a legal requirement. The FSA recommends communicating unintended allergen presence where it is a genuine risk you cannot remove. If you use it, base it on a real assessment of your kitchen, not on covering yourself.
Does the label need a date or a weight?
Not for PPDS specifically. Those are requirements for prepacked food sold elsewhere. Many businesses add a date anyway for their own stock control, and other rules may apply to your particular product.
What if an ingredient is obviously an allergen, like a bottle of milk?
Where the name of the food clearly refers to the allergen — ‘milk’ — the guidance says the indication is not required. In practice, for a made product with a full ingredients list, emphasise it anyway. It costs nothing and removes the judgement call.
