Who is this for?

MSC-first festival campers

If independently certified sourcing is your priority, check the exact tin for the blue MSC ecolabel. Broad sustainable-seafood wording does not establish that a particular product carries it.

Low-mess cold-meal campers

If draining liquid and handling wet waste will be awkward, look for a product explicitly described as no-drain or drained-and-ready.

Group and multi-meal packers

If you are feeding several people or planning more than one meal, compare usable quantity and portion sizes. Check how any opened leftovers must be stored before choosing a larger tin.

What matters when choosing?

For festival camping, decide what matters most on the exact tin: certified sourcing, low-mess handling, a portion you can finish, or a format that fits the meal.

Concern What to check Who this matters to
Certified sourcing Look for the blue MSC ecolabel on the exact tin; do not substitute a catch-method claim or retailer policy for it. If I want an independently certified fishery sourcing signal, a general sustainability statement is not enough. About 33% of consumers put that certification check first.
Low-mess use Check whether the pack explicitly says no-drain or drained-and-ready, and how it opens. With little space to prepare food or dispose of liquid, I want to open the tuna and add it to a cold meal without draining it. For about 27% of consumers, avoiding that handling is the primary need.
Leftovers Read the post-opening storage directions and choose a portion you can finish if refrigeration is unavailable. If I cannot keep opened food refrigerated at the campsite, I need a tin I can finish or share straight away. That is the main concern for about 20% of consumers.
Meal and portion fit Compare the packing liquid and stated net or drained quantity; use a consistent per-100g or per-serving basis for nutrition comparisons. For a planned cold meal or a group, I need the right amount of tuna and a liquid medium that suits how we will serve it. About 20% of consumers prioritise that match.

What should you avoid overlooking?

  • Assuming every sourcing claim means MSC certification

    According to the Marine Stewardship Council, its blue ecolabel identifies wild seafood from fisheries certified to the MSC Fisheries Standard. Pole-and-line wording or a retailer's wider seafood policy does not establish that the particular tin carries the label.

    If MSC certification is essential to your choice, check for the ecolabel on the physical pack.

  • Opening a large tin without a plan for leftovers

    The cited M&S and Princes product directions require opened leftovers to be refrigerated and used within two days. An unopened tin's storage directions do not continue to apply once it has been opened.

    Choose a portion you can finish, or share a larger tin when you open it, if you cannot refrigerate leftovers. Follow the directions on your exact pack.

    Without suitable storage, unused tuna may have to be discarded.

  • Comparing tins by their headline weight alone

    A drained-and-ready portion, a standard tin in spring water and tuna in oil need not provide the same amount of tuna or suit the same preparation plan.

    Check the stated drained quantity where available, as well as ingredients and the packing liquid. Compare nutrition figures on the same per-100g or per-serving basis.

  • Skipping the label and tin-condition checks

    Fish is an allergen, and cited tuna products warn that bones may remain. The cited Princes product information also says not to consume a swollen or damaged tin.

    Read the ingredients and allergen declaration for the exact variant, inspect the tin before use and take a suitable utensil for opening and eating.

Brands to consider

John West

John West offers No Drain tuna in spring-water and sunflower-oil formats. Its cited spring-water product is identified as MSC-labelled.

  • The No Drain format avoids a separate draining step; the cited product information also describes a SmartStrip opening system.
  • Check the liquid medium on the exact pack. John West directs consumers to refrigerate opened leftovers and use them within two days, and warns that bones may remain.

Princes

Princes lists MSC tuna chunks in several packing liquids, including spring water, brine and sunflower oil.

  • Its April 2026 catalogue lists a 145g MSC tuna-chunks format and a 4 x 145g format.
  • Princes says it has completed a commitment to MSC-certify all its tuna. Check the individual retail pack for its label, format and storage directions rather than relying on the brand-wide statement alone.

Sainsbury's

Sainsbury's lists a 120g Tuna Drained & Ready Water product for shoppers seeking a spring-water portion without a draining step.

  • The cited product page says its skipjack is pole-and-line caught and comes from an MSC-certified fishery.
  • Check the physical pack for its current sourcing statement, ingredients and storage directions, as product details can change.

M&S

M&S describes its cited tuna steak and spring-water chunks as pole-and-line caught.

  • The cited product pages give ingredients and post-opening refrigeration directions.
  • Those cited pages do not establish an MSC ecolabel claim for these products. Do not treat pole-and-line wording as equivalent to seeing that label on the tin.

Tesco

Tesco lists standard tinned-tuna formats and has published a tuna-sourcing policy.

  • Its grocery range includes different packing liquids, allowing shoppers to check the format that suits their meal.
  • Tesco's 2021 statement set a goal of MSC certification across its tuna ranges by 2025; that historical target does not establish the label status of an individual tin. Check the pack.

Asda

Asda publishes a seafood-sourcing approach and lists branded tuna products, including a Rio Mare olive-oil tuna product identified as MSC-certified.

  • The cited Rio Mare listing identifies the product's MSC status and gives post-opening storage directions.
  • Asda's wider sourcing statements do not establish certification for every own-label tuna tin. Check the exact product label.

Frequently asked questions

How can I check whether a tuna tin is MSC-certified?

Look for the blue MSC ecolabel on the exact tin. The Marine Stewardship Council says the label applies to wild seafood from fisheries certified to its Fisheries Standard; pole-and-line wording or a retailer's sourcing policy alone does not establish that the product carries it.

Which tuna format involves less draining at a festival?

Choose a pack explicitly described as no-drain or drained-and-ready if you want to avoid disposing of liquid. John West's cited No Drain product and Sainsbury's cited Drained & Ready product are examples; check the exact pack for its other details, including storage directions.

Can I keep leftover tuna in my tent after opening a tin?

Do not plan to keep opened leftovers at ambient temperature: the cited M&S and Princes product directions require refrigeration and consumption within two days. If refrigeration is unavailable, choose a portion you can finish when you open it and follow its own label directions.

What should I check before packing the tins?

Read the ingredients and fish-allergen declaration for each variant, and allow for product warnings that bones may remain. Inspect each tin before use; the cited Princes product information says not to consume a swollen or damaged tin.
