Students planning several tuna dinners
Multipacks can provide separate tins for pasta, rice, jacket potatoes or sandwiches. Check the pack size and drained weight when deciding how a format fits your meals.
Who is this for?
Students checking sustainable sourcing
If an independently assessed environmental claim matters to you, look for the blue MSC ecolabel on the exact product. The Marine Stewardship Council says it identifies wild-caught seafood from fishing practices assessed against its environmental requirements.
Students with limited kitchen facilities
A no-drain pot avoids draining tuna before adding it to a sandwich or another quick meal. Check its portion size against the meal you intend to make.
What should you check?
Start with certification on the exact product, then choose a pack format and packing liquid that suit the dinners you make.
| Priority | What to check | Your needs |
|---|---|---|
| Sourcing | Look for the blue MSC ecolabel on the exact tin or multipack. The Marine Stewardship Council says the label identifies wild-caught seafood from fishing practices independently assessed against its environmental requirements. | I want a product-level sourcing claim, not an assumption based on the brand or retailer. |
| Pack format | Compare the number of tins, each tin’s weight and any stated drained weight. A 4 x 145g multipack and a 3 x 100g no-drain pack provide different amounts and ways to serve them. | For several dinners, I want separate portions I can use across meals; when draining is awkward, a no-drain portion may suit me better. |
| Ingredients | Read the packing-liquid and ingredient lists. Princes lists tuna and spring water for its Tuna Chunks in Spring Water; flavoured products need checking individually for their ingredients and nutrition values. | I may want plain tuna to add to a sauce, or a flavoured tin when its listed ingredients fit the dish. |
| Dietary fit | Check the fish-allergen declaration. The NHS states that fresh and canned tuna do not count as oily fish and gives separate tuna limits for people who are pregnant or trying for a baby. | If an allergy or the NHS pregnancy guidance applies to me, those details affect which product I can use and how often. |
Common buying mistakes
-
Assuming every tin from a brand has the same certification
A general sourcing statement does not establish that the particular tin in your basket carries the MSC ecolabel.
Check the exact pack for the blue label and read any product-specific certification details.
-
Counting tinned tuna as oily fish
The NHS says fresh and canned tuna do not count as oily fish, so a tuna dinner does not serve that role in its fish guidance.
If you are following that guidance, check the type of fish rather than treating all tinned fish as interchangeable.
-
Overlooking relevant label and intake information
Tuna contains fish, an allergen. The NHS also advises people who are pregnant or trying for a baby to have no more than four cans of tuna a week or two tuna steaks a week.
Read the current ingredient and allergen declaration, and account for the NHS limit if it applies to you.
Brand and retailer references
These examples show why certification and ingredients should be checked on the particular product, not assumed across a range.
Princes
Princes lists MSC-labelled 4 x 145g tuna-chunk multipacks in spring water and brine in its product catalogue.
- The Princes catalogue identifies these specific multipack variants as MSC products.
- Check the variant on the pack: Princes lists tuna and spring water as the ingredients for its spring-water product, rather than for every packing liquid.
Sainsbury's
Sainsbury's has listed own-label 4 x 145g tuna chunks in spring water and brine, as well as individual flavoured products.
- Its Dill & Pickle Skipjack Tuna product page states that the fish is pole-and-line caught and MSC certified.
- Sainsbury's described an own-label sourcing commitment in May 2023; check the current label of a different multipack rather than transferring the individual product’s certification to it.
John West
Tesco listed a John West MSC no-drain spring-water tuna product in a 3 x 100g format.
- The named no-drain format offers portions that do not need draining.
- The MSC identification applies to the named variant; check the label on any other John West product separately.
Tesco
Tesco’s tinned-tuna listings include branded products identified as MSC alongside own-label tuna.
- Listings for the named Princes and John West formats provide pack details useful for choosing portions.
- The presence of MSC-labelled products in a retailer’s range does not establish certification for each own-label tin.

Frequently asked questions
How can I check a tin’s sustainability claim?
Look for the blue MSC ecolabel on the exact tin or multipack. The Marine Stewardship Council says it means the wild-caught seafood comes from fishing practices independently assessed against its environmental requirements; a general brand claim does not establish that an individual product carries the label.
Should I choose spring-water or flavoured tuna for dinner?
Choose according to the dish and the particular product’s ingredients. Princes lists tuna and spring water for its Tuna Chunks in Spring Water, which you can combine with your own sauce or seasoning; for a flavoured tin, read its ingredient and nutrition label before deciding whether it fits the meal.
Does tinned tuna count as oily fish?
No. The NHS states that fresh and canned tuna do not count as oily fish, so check the type of fish if you are following its fish guidance.
What should I check if I am pregnant or have a fish allergy?
The NHS advises people who are pregnant or trying for a baby to have no more than four cans of tuna a week or two tuna steaks a week. Tuna is fish, so anyone with a fish allergy should check the exact ingredient and allergen declaration and avoid products containing it.
