What to check when buying
Decide whether intact pieces are essential to the plate, then check the packing medium and usable quantity against your meal plan.
| Concern | What to check | Who this matters to |
| Intact pieces |
Look for “steak” or “fillets” on the pack; check the drained quantity for the portions needed. |
I want the tuna to remain visible beside potatoes and vegetables rather than disappear into a mixture. About 33% of consumers put intact presentation first. |
| Flavour control |
Read the packing medium and added flavourings; compare the product’s stated salt and fat values on the same per-100g basis. |
If I am adding my own dressing or serving strongly flavoured accompaniments, I want to decide how much flavour comes from the tuna pack. For about 27% of consumers, that control is the primary concern. |
| Portions and leftovers |
Check whether the pack is no-drain or resealable, and follow its instructions for storage after opening. |
When I need only part of a pack, handling the remainder matters as much as opening it neatly. Around 20% of consumers prioritise manageable portions and leftovers. |
| Enough fish for the table |
Use labelled drained weight and serving information, rather than tin count alone, to plan the quantity. |
For a meal shared by several people, I need enough usable tuna without discovering at serving time that the tins hold less fish than expected. Roughly 20% of consumers put household quantity first. |

Common questions
Are tinned tuna fillets the same as fresh fish fillets?
No. “Fillets” describes the form of the tuna in the container, not fresh raw fish. If the meal calls for a fresh fillet to cook from raw, choose a product sold for that purpose; for tinned tuna, follow the particular pack’s preparation instructions.
Should I buy tuna steaks, fillets or chunks for a roast-dinner-style plate?
Choose a tin labelled steak or fillets when intact, visible pieces matter. Chunks are a different format that may suit a sauce, filling or other dish where the fish will be mixed in.
How should I store tuna after opening it?
Follow the directions for the exact product. Sainsbury’s instructs shoppers to transfer the remainder of its cited sunflower-oil tuna steak to a non-metallic container, refrigerate and use within one day; its listing for the John West fridge pot says to replace the lid, refrigerate and use within two days.
Does tinned tuna contain a fish allergen?
Yes, tuna is fish, and the cited ingredient lists identify fish as an allergen. Check the current pack’s complete allergen statement before serving it to anyone who needs that information.
Does tinned tuna count as oily fish?
No. The NHS classifies neither fresh nor canned tuna as oily fish. Packing tuna in oil does not change that NHS classification.
