If independent sustainability certification matters most, choose a tinned tuna product carrying the blue MSC label on the exact pack rather than relying on a brand-wide sourcing claim. For Christmas meals, choose chunks in spring water or brine for mixed dishes, a no-drain format for quicker preparation, or an oil-packed steak when flavour and presentation are the priority; check the sourcing claim separately for each option.
If you are stocking up for festive lunches or visiting family, you may want certification you can identify on each tin. The Marine Stewardship Council says its Chain of Custody standard is designed to keep certified seafood identifiable and traceable through the supply chain; a general brand promise is not a substitute for checking the product.
For sandwiches, salads or jacket-potato fillings prepared alongside other Christmas food, a no-drain pack can remove the separate draining step. John West lists MSC-labelled no-drain tuna products, but the label still needs checking on the particular variant you buy.
If tuna will be prominent in a salad or platter, the choice between chunks and steak, and between water and oil, may matter as much as ease of preparation. Check the sourcing statement on that exact product rather than assuming its format establishes certification.
Start with the sourcing evidence required for your shop, then match the liquid, pack format and pieces of fish to the dishes you plan to make.
| Concern | What to check | Who this matters to |
|---|---|---|
| Product-specific certification | Look for the blue MSC label on the exact pack and variant. | If certification is non-negotiable for my Christmas shop, I want evidence on each tin rather than a general brand pledge; about 36% of consumers put product-specific certification first. |
| Quantity for several meals | Compare the number of tins and their drained weights against your planned recipes. | When I need tuna for sandwiches, jacket potatoes and a pasta bake, the amount I can use across those meals comes first; that is the primary concern for about 29% of consumers. |
| Quick preparation | Check whether the pack says no-drain or drained-ready, and note its packing liquid. | If I am assembling buffet food and quick lunches, I would rather avoid handling extra liquid; roughly 21% of consumers prioritise that preparation need. |
| Flavour and presentation | Choose between chunks and steak, and check whether the tuna is packed in water, brine or oil. | For a salad or platter where the tuna stays visible, I care most about the pieces and their flavour; about 14% of consumers make that their main consideration. |
Certification is tied to the labelled product. A brand may sell different tuna formats without the same certification claim on every variant.
When MSC certification is essential, check the blue label on the exact tin you intend to use.
Pole-and-line describes a catch method. The Marine Stewardship Council’s label identifies certified sourcing with Chain of Custody traceability requirements; the two claims answer different questions.
Choose a clearly labelled pole-and-line product if that method is your priority, but only call the tin MSC-certified when the exact product carries the MSC claim.
Pack weight, drained weight and packing liquid are different details. A no-drain pack for sandwiches and an oil-packed steak for a platter may serve different purposes even when their tins appear similar in size.
Check drained weight where stated, then choose chunks or steak and the packing liquid to suit the meals you are making.
Tuna is fish, which the Food Standards Agency identifies as an allergen. Warnings and instructions for opened products can also differ between packs.
Check allergen information before serving guests, read the exact tin for warnings, and follow its refrigeration and use-after-opening instructions.
These examples show why the sourcing claim needs checking at product level: an MSC label and a stated catch method are not interchangeable.
Its No Drain Tuna Chunks range includes spring-water and sunflower-oil products identified as MSC-labelled in the examined product listings.
The Princes product catalogue lists MSC tuna chunks in several pack formats, including brine and spring-water alternatives.
M&S describes its Tuna Chunks in Spring Water as pole-and-line caught under its Forever Fish sourcing policy.
Its Taste the Difference albacore tuna steak in extra-virgin olive oil is listed as pole-and-line caught.
This no-drain tuna multipack is an option for quick Christmas sandwiches and salads when product-specific MSC labelling is also part of the decision.

For quick festive sandwiches or salads, the no-drain format avoids a separate draining step.
Sainsbury’s identifies the matching 3 × 100 g spring-water product as MSC-labelled. Check the blue label on the cans you receive if certification is essential to your choice.
Look for the blue MSC label on the exact tin or product variant, rather than relying on the brand name alone. The Marine Stewardship Council says its Chain of Custody standard is designed to keep certified seafood identifiable, separate from non-certified products and traceable through the supply chain.
No. Pole-and-line names a catch method, while MSC labelling identifies certified sourcing and associated traceability requirements. If you want both, check that the particular pole-and-line product also carries the MSC label.
Spring water or brine gives you chunks that you can combine with your own dressing for sandwiches, pasta bakes or salads. Consider an oil-packed steak when its flavour and larger pieces suit a dish where the tuna is prominent; compare the individual labels if ingredients or nutrition values affect your choice.
Check the pack’s allergen warnings and its instructions for refrigeration and use after opening. Tuna is fish, an allergen identified by the Food Standards Agency, so this check is particularly important when serving guests whose dietary requirements you do not know.
