Households making sandwiches, wraps or pasta pots
Tuna can provide the fish element of a packed lunch. Bedfordshire Community Health Services NHS Trust advises including starchy food and fruit or vegetables too.
Who is this for?
Households managing a fish allergy
Tuna is unsuitable for a pupil with a fish allergy. GOV.UK identifies fish as an allergen that must be declared when it is an ingredient in UK prepacked food; check the physical pack each time.
Households preparing lunch with less mess
A no-drain pack removes the separate draining step. Check the particular pack’s ingredients, allergen information and instructions for any tuna left after opening.
What should you check when choosing tinned tuna?
Start with whether tuna is suitable for the pupil, then compare the format, nutrition label and tin size against how the lunch will be prepared.
| Priority | What to check | Your needs |
|---|---|---|
| Fish allergy | Read the ingredients and allergen information on the physical pack. GOV.UK says fish must be clearly labelled when present in UK prepacked food. | If the pupil has a fish allergy, I need a lunch without tuna. |
| Lunch format | Choose plain chunks for a tuna base, a stated no-drain product to skip draining, or chunks and flakes for a mixed filling. Check the exact product rather than assuming every tin in a range has the same format. | I might use tuna in a sandwich one day and a pasta pot another; on a hurried morning, avoiding a draining step may matter more. |
| Lunch components | Plan a starchy base and fruit or vegetables alongside the tuna. Bedfordshire Community Health Services NHS Trust recommends including foods from these groups in a packed lunch. | For a tuna wrap or pasta pot, I want to plan the rest of the lunch as well as the filling. |
| Salt and portion | Compare salt per 100g on the same drained-product basis, then check how much tuna the planned portion uses. The reviewed Sainsbury’s 145g tin lists 0.12g salt per 100g drained; the reviewed Asda 4 x 145g pack lists 0.90g. | If salt matters in my household’s choice, a spring-water label alone does not tell me how the tins compare. |
| Tin size and leftovers | Check the tin or multipack size against one preparation session. Read the exact pack’s directions for transferring, refrigerating and using any leftovers. | A tin that fits the amount I usually prepare may be simpler than planning another use for opened tuna. |
Common mistakes when buying tuna for packed lunches
-
Assuming spring-water tuna has a uniform salt value
Reviewed product labels differ: Sainsbury’s lists 0.12g salt per 100g drained for its 145g tin, while Asda lists 0.90g for its 4 x 145g pack.
Compare the current packs on the same per-100g basis and consider the portion you intend to use.
-
Making tuna the entire lunch
Tuna does not supply all the food groups in Bedfordshire Community Health Services NHS Trust’s packed-lunch guidance.
Put it in a sandwich, wrap or pasta pot and include fruit or vegetables.
-
Overlooking instructions after opening
Directions differ by product: the reviewed Sainsbury’s tin says to refrigerate and use within one day, while the reviewed Tesco 4 x 160g product says to transfer unused contents to a covered non-metallic container, refrigerate and consume within two days.
Follow the instructions on your pack and choose a tin size that fits your likely use.
-
Treating a short ingredient list as allergy-safe
Plain tuna still contains fish. GOV.UK identifies fish as an allergen that must be declared when it is an ingredient in UK prepacked food.
Do not pack tuna for a pupil with a fish allergy; read the physical pack’s allergen information each time.

Questions about tuna packed lunches
Can a pupil with a fish allergy have tinned tuna?
No. Tuna is fish, so exclude it for a pupil with a fish allergy. GOV.UK says fish must be clearly labelled in the ingredients list when it is present in UK prepacked food; check the physical pack rather than relying on a range name.
Is tuna on its own enough for a packed lunch?
No. Use it as one part of the lunch: Bedfordshire Community Health Services NHS Trust advises including a starchy food and fruit or vegetables alongside a protein food. A tuna sandwich, wrap or pasta pot can provide the base for that combination.
What should I do with tuna left after opening a tin?
Follow that product’s storage instructions and refrigerate leftovers. The reviewed Sainsbury’s 145g tin says to use them within one day; the reviewed Tesco 4 x 160g product says to transfer them to a covered non-metallic container and consume within two days.
Should I check the school’s rules before packing tuna?
Yes. Check the individual school’s current lunch and allergy policy before sending a tuna packed lunch. Tuna contains fish, so also check the pupil’s own allergy requirements.
