Who each format suits

Cupboard-stockup households

If you want tuna available for meals on different days without setting aside freezer space, unopened tins offer the relevant storage format. Multipacks divide the stock into separate cans; with a larger can, consider whether you can use the remainder within the instructions on its label.

Fresh-steak meal planners

If the meal calls for a chilled tuna fillet or steak, buy it for a specific cooking date. Check its use-by date before adding extra packs to a bulk shop, and freeze it on or before that date if your plans change, in line with GOV.UK guidance.

Label-conscious repeat buyers

If packing liquid, ingredients or salt per 100g affect your choice, compare the labels of the exact variants you intend to buy. Fish is a declarable allergen in UK prepacked foods containing it, so anyone buying for a person with a fish allergy needs to check the current ingredients label.

What matters when choosing

Decide whether the shop is mainly for flexible cupboard meals or a particular fresh-fillet dish; then check pack yield, storage instructions and the label details that matter to you.

Tinned tuna

Choose when: You want unopened cans for meals spread over time rather than a fixed cooking date.

Bear in mind: Chunks and tinned steaks are not chilled fresh fillets, and the contents of an opened can need prompt refrigerated use.

Fresh tuna fillets or steaks

Choose when: A planned cooked meal calls for the fresh fillet or steak format.

Bear in mind: Chilled packs have a use-by date, so buying several requires a meal plan or space to freeze them in time.

Concern What to check Who this matters to
Storage and usable portions Check drained weight per can and the instructions for storing and using tuna after opening. If I am stocking the cupboard for meals on different days, I need cans whose portions I can use without leaving too much from an opened pack. About 50% of consumers put storage and manageable leftovers first.
Fresh fillet meals Check the fillet or steak format, use-by date and whether you can freeze packs before that date. For a particular cooked dish, I want a fresh fillet rather than ready-to-use tinned chunks, and I can plan when to cook it. Fresh-steak meals are the primary need for about 30% of consumers.
Ingredients and format Compare packing liquid, ingredients, salt per 100g and fish-allergen labelling on the current pack. When I buy the same tuna regularly, I want to know whether it comes in water, brine or oil and what its label says. Roughly 20% of consumers make these label and format details their first concern.

Bulk-buying mistakes to avoid

  • Judging the amount of tuna by the weight on the front of the tin

    The stated can weight includes packing liquid. Tesco lists 280g drained weight for its 400g spring-water can and 3 × 56g drained for its 3 × 80g pack; the front-of-pack weights alone do not tell you how much drained tuna you will have.

    Check the drained weight and work out whether the usable portions fit the meals you have planned.

  • Putting fresh tuna in the trolley without a use date in mind

    Fresh fillets and steaks do not offer the same cupboard-storage flexibility as unopened tins. GOV.UK advises cooking or freezing food on or before its use-by date.

    Assign fresh packs to planned meals before buying several, and check that you can freeze any packs you will not use in time.

  • Assuming every tin has the same ingredients

    Spring-water, brine and oil-packed tuna are distinct variants. The liquid and the information on the nutrition label can change with the exact product, so one variant should not stand in for another when checking ingredients or salt per 100g.

    Choose a format that works for the recipe, then read the label of the particular pack rather than relying on its brand name.

  • Overlooking the instructions after opening a large can

    An unopened tin may be suitable for cupboard storage, but that does not apply to leftover contents. The cited Princes and John West product instructions call for refrigeration after opening and use within two days.

    Plan the remaining portions before opening the can and follow its instructions for transferring and refrigerating unused tuna. Check the current ingredients label when buying for someone with a fish allergy.

Brands and ranges to consider

These examples show different pack and tuna formats; check the exact variant, as a brand name alone does not establish its drained weight, ingredients or storage instructions.

John West

John West chunk multipacks, no-drain products and tinned steak formats appear in the cited Tesco and Sainsbury's listings.

  • The cited brine multipack contains four 125g cans, each listed with 102g drained weight.
  • Sainsbury's instructs buyers of that brine pack to refrigerate it after opening and consume it within two days.

Princes

Princes offers tuna-chunk multipacks in spring water and brine, alongside other listed tuna formats.

  • The cited spring-water option is a four-pack of 145g cans, allowing cans to be opened for separate meals.
  • ASDA's instructions for that spring-water pack say to refrigerate the contents after opening and use them within two days.

Tesco

Tesco own-label includes both smaller spring-water multipacks and a larger single can.

  • Tesco lists a 400g spring-water can with 280g drained weight and a 3 × 80g pack with 3 × 56g drained.
  • A larger single can leaves more to use after opening, so check its storage instructions against your meal plan.

Sainsbury's

Sainsbury's own-label listing includes four-packs of tuna chunks in spring water, brine, sunflower oil and olive oil.

  • The listed liquids give shoppers several ingredient and recipe formats within the four-pack range.
  • Check the exact variant rather than assuming its ingredients or nutrition information match another pack in the range.

Asda

Asda own-label includes a single 145g spring-water tuna-chunks can.

  • A single can lets you assess whether that portion and format suit your meals before choosing a larger stock-up.
  • One can does not provide the separate unopened portions of a multipack; decide how many meals you are stocking for.

M&S

The Marks & Spencer tinned-fish listing includes chunks, steaks and larger listed pack formats.

  • Listed examples include 640g tuna chunks and an 800g tuna-steak format.
  • For its spring-water chunks, M&S instructs customers to move unused contents to a non-metallic container, refrigerate them and eat them within two days.

Questions about buying and storing tuna

Should I bulk-buy tinned tuna or fresh fillets?

Buy tinned tuna when you want unopened cupboard stock for flexible meals; buy fresh fillets for a planned cooked dish. If you buy extra fresh packs, check their use-by dates and whether you can freeze them on or before those dates, as GOV.UK advises.

Does the weight on a tuna tin tell me how much tuna I will get?

Not if the tin contains packing liquid: check its drained weight as well. Tesco lists 280g drained for a 400g spring-water can and 3 × 56g drained for its 3 × 80g pack, so plan portions using the drained figures.

How should I keep tuna left over from an opened can?

Follow the instructions on the exact pack rather than treating an opened can like unopened cupboard stock. The cited Princes, John West and M&S product instructions call for refrigeration and use within two days; some specify transferring the contents to a non-metallic container.

What should I check when buying tuna during pregnancy or for someone with a fish allergy?

For someone who is pregnant or trying for a baby, NHS guidance sets a limit of no more than four cans of tuna a week or two tuna steaks a week because of mercury. For a fish allergy, check the current ingredients label: GOV.UK says fish must be clearly declared when it is an ingredient in prepacked food.
