What to check before choosing
Start with the dish and the number of portions, then compare can labels for the format and preparation that suit it.

What to check |
Your needs |
| Quantity |
Check the number of cans, the weight of each can and its drained weight. Work out how many cans the planned dish will use. |
For a family pasta bake, I want enough tuna for the portions I am making without opening more cans than necessary. |
| Packing liquid |
Read whether the tuna is packed in spring water, oil or brine. Compare nutrition figures on the same per-100g drained basis where labels provide them, and check the salt value. |
If my recipe supplies its own sauce, I may prefer spring-water chunks. For a dish using oil-packed tuna, I want the oil to suit its flavour. |
| Preparation and texture |
Check whether draining is required and whether the product contains chunks or steaks. John West labels a separate spring-water chunks product No Drain; M&S describes its spring-water tuna steak as already drained. |
On a quick jacket-potato night, avoiding a draining step matters to me. If the tuna will remain visible in the dish, I may choose pieces labelled as steaks. |
| Sourcing information |
Look for a sourcing statement or ecolabel on the exact can. Do not extend a claim from one product to every item made by the brand. |
I want to know which sourcing statement applies to the tuna I am putting in the cupboard, not just to the brand generally. |
| Household checks |
Read the fish allergen declaration, any bone warning and the opened-can storage instructions. Check current NHS pregnancy food guidance if it applies to someone eating the meal. |
When sharing tuna with children or preparing food for someone with a fish allergy, I need the exact can’s warnings and ingredients to hand. |
Relevant brand references
These examples show why the exact product line matters; a brand name alone does not establish a can’s format or label details.
John West
A reference for shoppers considering a no-drain spring-water format alongside conventional chunks.
- John West identifies its No Drain Tuna Chunks in Spring Water MSC as a separate product line.
- Check that a particular pack says No Drain before choosing it to avoid a draining step.
Princes
A reference for comparing chunk pack sizes and packing liquids.
- Princes lists spring-water chunks in formats including 145g single cans and multi-packs up to 8 x 145g.
- Its sunflower-oil chunks are a different variant; check their ingredients and nutrition separately from the spring-water product.

- Tesco’s tinned-tuna category lists a 4 x 145g spring-water chunks pack.
- Check the pack’s drained quantity against the servings needed for your meal.
M&S
A reference for comparing spring-water chunks with a tuna-steak format.
- M&S describes its 640g spring-water chunks product as a four-pack and its spring-water tuna steak as already drained.

Questions about buying and using tinned tuna
Should I choose spring-water or sunflower-oil tuna for a family dinner?
Choose by the recipe and compare the labels on the exact products. Spring-water chunks provide a base when you plan to add sauce or dressing; sunflower-oil chunks bring oil into the dish. Princes lists 180kcal and 9.5g fat per 100g drained for its sunflower-oil chunks, so do not apply another variant’s nutrition figures to them.
How should I keep tuna left over from an opened can?
Follow the instructions on your can. For its 160g Tuna Chunks in Spring Water, M&S says to transfer unused contents to a non-metallic container, refrigerate them and eat them within two days; instructions for another product may differ.
What should I check when serving tinned tuna to children?
Check the exact can’s fish allergen declaration and any warning about bones before preparing the meal. Take care when flaking tuna into a filling or mixed dish, where small pieces may be less noticeable.
Does pregnancy change what to check when planning tuna meals?
Yes. The NHS warns that tuna can contain pollutants, including mercury, that may be harmful to a baby if too much is eaten. If this applies to your household, consult the NHS’s current pregnancy food guidance when planning meals across the week.
How can I check a tuna sourcing claim?
Look for the sourcing statement or ecolabel on the exact can or its current product information. A claim attached to one tuna line does not automatically describe another format or packing liquid from the same brand.
