Shoppers avoiding a diagnosed food allergen
Check each flavour’s current ingredients and precautionary wording against your individual avoidance plan. A familiar brand name does not tell you whether a particular pack meets it.
Who needs to check what?
Parents and carers buying snacks for an allergic child
Check the physical pack when buying it and again before serving it. Leeds Teaching Hospitals NHS Trust advises checking every time because recipes can change, sometimes with the change shown only in the ingredients list.
Gluten-free shoppers avoiding another allergen
A gluten-free range can help identify products relevant to gluten avoidance, but it does not answer questions about milk or other separate allergens. Check the chosen flavour and pack for each allergen that matters.
What matters when choosing crisps?
Screen the exact pack for the allergens you avoid, then compare the pack sizes and flavours that remain suitable.
| Priority | What to check | Your needs |
|---|---|---|
| Current ingredients | Read the exact flavour’s ingredient list on the pack. Check it when buying and before eating; Leeds Teaching Hospitals NHS Trust notes that recipes can change. | I need to know whether this particular bag lists an allergen I avoid, even if I have bought the flavour before. |
| Precautionary wording | Look for statements such as “may contain” or “made in a factory that also handles”. The Food Standards Agency describes precautionary allergen information as communicating possible unintentional presence, rather than an intentionally added ingredient. | A short ingredient list alone is not enough for me; any relevant cross-contact wording must fit my individual avoidance plan. |
| Dietary claims | Check what a gluten-free or vegan claim actually covers, then read the ingredients and allergy wording for the chosen flavour. A claim about one dietary requirement does not settle a different allergen question. | I may be looking for gluten-free crisps while also needing to avoid milk or another allergen. |
| Pack comparison | After screening the labels, compare the net weights of packs you can use. Keep flavours and pack types comparable rather than treating every bag as interchangeable. | I want a useful pack size without letting a larger bag distract from its allergen information. |
Common buying mistakes
-
Choosing the brand instead of the flavour
Ingredients and allergy wording can differ across a range. A gluten-free claim also does not address every other food allergen.
Read the current pack for the exact flavour, including its ingredients and any precautionary statement, before comparing it with another option.
-
Assuming plain crisps have no relevant warnings
Tyrrells says its two-ingredient Naked crisps may contain milk. Walkers says its Ready Salted crisps are made in a factory that also handles several named allergens.
Use a plain flavour only if both its ingredients and precautionary wording fit the shopper’s individual avoidance plan.
-
Judging a pack’s value before checking suitability
A larger bag is not a useful option if its label conflicts with the shopper’s allergen-avoidance plan.
Screen the pack first, then compare the net weights of the eligible options.
Brand and range references
These examples show why allergy checks belong to individual products and flavours, not to a brand name.
Walkers
Walkers Ready Salted provides an example of a plain-flavour product with separate ingredient and factory-handling information.
- Walkers lists potatoes, vegetable oils, salt and antioxidants as ingredients for Ready Salted.
- Its product page says the factory also handles milk, wheat, gluten, barley, soya, celery and mustard. Check whether that wording fits the shopper’s plan.
Tyrrells
Tyrrells Naked illustrates the difference between a short ingredient list and precautionary allergy advice.
- Tyrrells lists potatoes and sunflower oil for Naked.
- The same product page says “may contain milk”. That warning remains relevant despite the two-ingredient list.
Kettle Chips
Kettle Chips directs shoppers to the dietary and allergy advice on individual bags.
- Kettle Chips states that its chip range contains no nuts or sesame seeds and that neither is handled in its factory.
- That brand statement does not replace checking the current bag for other allergens relevant to the shopper.
Seabrook
Seabrook describes its crisps and snacks as gluten-free and Coeliac UK accredited.
- Seabrook lists potatoes, vegetable oils and sea salt for its Sea Salted crisps.
- A range-level gluten-free claim does not establish suitability for an unrelated food allergy; check the chosen flavour.
McCoy’s
McCoy’s flavoured and salted crisps call for a flavour-by-flavour label check.
- The exact pack’s ingredient and allergy information lets shoppers assess the flavour they intend to buy.
- Do not assume the wording on one McCoy’s flavour applies to another.
REAL Hand Cooked Crisps
REAL describes its range as vegetarian and gluten-free and provides flavour-level allergen information.
- REAL lists potatoes, vegetable oils and sea salt for its Sea Salt flavour.
- Its range-level claims do not answer every other allergen question; inspect the chosen pack.

Questions about crisp labels
Do packaged crisps in the UK have to provide allergen information?
Yes. The Food Standards Agency says food businesses must provide allergen information for prepacked food. Check the information on the exact crisp pack and flavour you intend to buy.
What do “may contain” and factory-handling statements mean?
They communicate possible unintentional presence of an allergen, rather than declaring it as an ingredient. The Food Standards Agency describes these as forms of precautionary allergen information; assess the named allergen against the shopper’s individual avoidance plan.
Can I rely on a crisp flavour I have bought before?
No. Check its ingredients and allergy wording again at purchase and before eating. Leeds Teaching Hospitals NHS Trust advises checking every time because a recipe change may appear only in the ingredients list.
Does gluten-free mean suitable for every food allergy?
No. A gluten-free claim concerns gluten; it does not establish whether a crisp meets requirements for milk or another separate allergen. Even when choosing from a range that describes itself as gluten-free, check the exact flavour’s current pack.
