Sustainability-first home workers
You want a quick lunch and a certification claim you can identify on the tin itself. The MSC ecolabel is a distinct claim from a brand or retailer statement that tuna is responsibly sourced.
Who this is for
Between-meetings lunch makers
You need tuna for a sandwich, salad, wrap or jacket potato without spending much of your break draining and portioning it. The format, tin size and instructions for leftovers matter alongside the sourcing claim.
Multipack lunch planners
You want a pack that fits the number of lunches you make. Check how much tuna each tin provides after draining and whether the packing medium suits the meal, rather than judging a multipack by its tin count alone.
What to check when choosing
For a work-from-home lunch, start with the sourcing claim on the exact product, then check whether its format and ingredients suit the meal you plan to make.
| Concern | What to check | Who this matters to |
|---|---|---|
| Identifiable certification | Look for the MSC ecolabel on the particular tin; do not treat pole-and-line wording as the same certification. | If I want a sustainability credential I can recognise at a glance, a general sourcing statement does not answer that need. About 50% of consumers put identifiable certification first. |
| Low-mess preparation | Check whether the tuna needs draining and whether one tin suits your lunch portion. | When my lunch break falls between calls, opening and serving the tuna quickly matters more than comparing every format. Roughly 30% of consumers make preparation convenience their primary concern. |
| Portion and recipe fit | Compare net and drained weights, then read the packing medium, ingredients and nutrition panel. | For sandwiches or salads across several lunches, I need a usable portion and a packing medium that suits the recipe. Around 20% of consumers prioritise that fit. |
Common buying mistakes
-
Treating every sustainability statement as an MSC ecolabel
Pole-and-line describes a catching method, while the MSC ecolabel identifies a separate fishery-certification scheme. A retailer sourcing policy is another distinct claim.
If third-party certification is essential to your choice, confirm the MSC logo on the specific tin. Otherwise, read the brand or retailer statement for what it actually promises.
-
Judging a multipack by its tin count
Net weight and drained weight describe different amounts, and a no-drain product may be portioned differently from conventional chunks. Tin count alone cannot tell you how much tuna is ready to put in lunch.
Check the weight information and decide whether avoiding the draining step matters for your usual portion.
-
Assuming water-packed and oil-packed tuna have the same nutrition
For its own tuna chunks, Princes lists 99kcal per 100g drained in spring water and 180kcal per 100g drained in sunflower oil. Those figures describe the named products, not every tuna tin.
Choose the packing medium for the flavour and recipe you want, then check that product’s ingredients and nutrition panel.
-
Overlooking the instructions for opened tuna
One tin may provide more than you use at lunch. Tesco Groceries lists instructions for the John West No Drain spring-water multipack to refrigerate it after opening and consume it within two days.
Follow the instructions on the pack you open and plan how you will store any leftover portion.
Brands to consider
John West
Its No Drain tuna offers a format for lunches assembled with little preparation.
- Tesco Groceries identifies the John West No Drain 3 × 100g spring-water multipack as MSC-labelled.
- Check the certification claim and ingredients on the exact variant: spring-water and sunflower-oil packs are different products.
Princes
Its tuna-chunks range includes spring-water, brine and sunflower-oil formats in the Princes product catalogue.
- Princes says it has completed its commitment to make its tuna MSC certified.
- Use the particular tin’s label to confirm its certification and packing medium rather than applying a company-wide statement to an individual variant.
M&S
Its 160g Tuna Chunks in Spring Water are described by M&S as pole-and-line caught under its Forever Fish sourcing policy.
- The product provides an option for shoppers specifically looking for a stated catching method and a spring-water format.
- That pole-and-line claim does not establish that the product carries an MSC ecolabel; check the pack if MSC certification is required.

This no-drain multipack suits a quick lunch when sunflower oil fits the recipe you are making. It contains three 100g tins. If MSC certification is central to your choice, check for the ecolabel on this exact pack; do not assume the spring-water variant’s label applies to it.
Frequently asked questions
How can I identify tinned tuna with MSC certification?
Look for the Marine Stewardship Council’s blue ecolabel on the particular tin or its product listing. The label relates to a certified fishery; it does not mean every tuna product from the same brand carries it.
Is no-drain tuna useful for a work-from-home lunch?
It can remove the draining step when you have little time to assemble a sandwich or salad. Check the tin size against the portion you intend to use and follow the pack’s instructions if you keep leftovers.
What should I do with tuna left after opening a tin?
Follow the instructions on that product. Tesco Groceries says to refrigerate the John West No Drain spring-water multipack after opening and consume it within two days; instructions may differ on another pack.
What allergen information should I check on tinned tuna?
Check the ingredients and allergen information on the exact product, particularly when choosing a flavoured or prepared variant with additional ingredients. GOV.UK identifies fish among the allergens for which food businesses must provide information.
