For a lunch assembled between lectures, choose a no-drain tuna steak pot if avoiding liquid and keeping an unfinished portion in a resealable pack matter most. An already-drained multipack also avoids draining, while a conventional spring-water tin is worth considering when you can handle the liquid and follow its leftover-storage instructions. These are shelf-stable tinned products, not chilled fresh tuna fillets; check the exact pack rather than assuming every product labelled ‘tuna steak’ has the same format.
If lunch needs to go straight into a sandwich, wrap or salad, look for no-drain or already-drained wording on the exact pack. A resealable pot can hold an unfinished portion, but the cited John West pot still requires refrigeration after opening.
Check how many portions a pack contains and whether you can use them within its opening and storage instructions. An individually sized pot, a multipack and a large tin create different leftover-handling needs.
Look for a catch method or certification stated for the exact product, rather than relying on the retailer name. The cited Sainsbury’s tuna steak states pole-and-line catch and MSC fishery certification; the cited M&S products make pole-and-line and traceability statements.
Choose when: You may assemble lunch away from a kitchen or leave some tuna for later. The cited John West fridge pot is labelled no-drain and resealable.
Bear in mind: Resealing does not replace refrigeration; the cited pot says to refrigerate it after opening and use it within two days.
Choose when: You want ready-to-use tuna for several lunches without choosing a resealable pot. Sainsbury’s describes the cited Princes 3 × 110g product as already drained.
Bear in mind: An opened portion needs covering, refrigeration and use within two days according to that product listing.
Choose when: You can open and prepare a tin where draining and storing leftovers are manageable.
Bear in mind: ‘Tuna steak’ alone does not establish a no-drain or resealable format. Follow the instructions on the particular tin.
| Priority | What to check | Your needs |
|---|---|---|
| Preparation | Look for no-drain or already-drained wording on the exact product. Check whether its container can be resealed. | I need to put lunch together between lectures without finding somewhere to drain a tin. |
| Pack and storage | Check the portion size, instructions after opening and whether leftovers need another container. The cited Sainsbury’s own-label tin specifies transfer to a non-metallic container, refrigeration and use within one day. | If I will not finish the pack at lunch, I need a way to store the rest as its label directs. |
| Ingredients and nutrition | Identify the packing medium and compare nutrition on the same per-100g basis. For example, Sainsbury’s lists 28g protein and 0.8g salt per 100g for its cited John West spring-water pot. | I want to know what is in the tuna and compare labels without confusing per-100g and per-serving figures. |
| Sourcing | Check the exact pack for a stated catch method, fishery certification and traceability information. Do not transfer a claim from one product to another. | A product-specific sourcing statement matters to me more than a general impression of the brand. |
‘Tuna steak’ describes the product, not a universal packaging format. The cited John West pot is no-drain and resealable, whereas the cited Sainsbury’s own-label tin gives instructions for transferring leftovers out of the can.
Check the format and opening instructions for the exact pack if you expect to prepare lunch away from a kitchen.
The cited spring-water products have different protein and salt figures per 100g. Packing medium and serving basis also matter when comparing labels.
Read the ingredients and compare per-100g figures for the products and variants you are considering.
The UK Food Standards Agency advises pregnant people and those trying for a baby to have no more than four medium cans of tuna or two tuna steaks in a week. Its guidance uses around 140g drained weight for a medium can and a 140g cooked steak.
When applying that guidance, distinguish tinned tuna from a cooked fresh tuna steak and check the drained weight of the cans you use.

No. Check the claim on the exact product: the cited Sainsbury’s tuna steak states pole-and-line catch and MSC fishery certification, while the cited M&S products make pole-and-line and traceability statements. Do not apply either product’s details to a different tin.
