For sandwiches and salads prepared before you leave, spring-water tuna chunks are a practical choice if you can drain them at home. Choose a no-drain pack if you will assemble food at the picnic, or tuna in oil when you want the oil in the dish. Compare the exact pack’s usable quantity, ingredients, nutrition and instructions for opened tuna before buying.
If you are preparing sandwiches, wraps or salads before leaving, standard tuna chunks give you portions to mix into the dish. Check the drained weight as well as the tin size, and plan what to do with any opened tuna you do not use.
A no-drain format reduces the need to handle packing liquid at the picnic site. Asda describes its John West No Drain spring-water chunks as ready to eat with a twist-and-pull opening; check the opening and contents on the particular pack you choose.
Look at the packing liquid, per-100g nutrition and fish allergen declaration on the exact tin. Sainsbury’s, Asda and Marks & Spencer also make sourcing claims for particular tuna products; a claim on one pack does not establish what is stated on another.
Decide where you will prepare the tuna, then check how much usable fish you need and whether the packing liquid suits the dish. The groups below are organised by consumers’ primary picnic-buying concern.
| Concern | What to check | Who this matters to |
|---|---|---|
| Preparation and mess | Look for no-drain or ready-to-eat wording, and check how the pack opens. | If I am mixing food at the picnic rather than at home, I want to handle as little liquid as possible. About 31% of consumers put easy outdoor preparation first. |
| Group portions | Check the number of tins, net and drained weights, and instructions for opened contents. | When I am making food for several people, I need enough tuna without leaving an opened tin unused. Portion planning is the primary concern for about 31% of consumers. |
| Liquid and recipe fit | Read the ingredients and compare nutrition on the same per-100g basis; check the fish allergen declaration. | For a dressed salad, I may want spring-water tuna; for another dish, I may want the oil as part of it. About 23% of consumers chiefly choose by packing liquid, nutrition and recipe fit. |
| Sourcing claims | Find the certification mark, catch-method statement or sourcing-policy wording on the specific pack. | If a stated fishing method or certification determines what I buy, a general impression of the brand is not enough. Specific sourcing information comes first for about 15% of consumers. |
Tins and multipacks can differ in size and in how much liquid they contain. The number of cans alone will not tell you how much tuna is available for sandwiches or salad.
Check the net and drained weights on each pack, then plan portions around the amount of fish you expect to use.
The listed Sainsbury’s spring-water chunks contain 0.12g salt per 100g drained, while the listed Asda spring-water chunks contain 0.90g per 100g drained. Those figures apply to the specific products, not every tin in either range.
Compare the nutrition panels on the exact packs using the same per-100g basis.
Instructions for leftovers can differ. Sainsbury’s says to transfer unused contents of its listed spring-water tuna to a non-metallic container, refrigerate and use within one day.
Plan how much to open at the picnic, and follow the storage and use instructions on the pack you take.
An opened portion that cannot be used within its stated refrigerated period may go to waste.
Certification, catch-method and retailer sourcing statements can be product-specific. A claim printed on one tuna pack does not establish the claim for other variants.
Check the mark or wording on the precise tin you intend to buy.
Relevant if you want to consider a no-drain format for food assembled outdoors.
Relevant for comparing drained tuna in spring water with a drained sunflower-oil variant.
Its tinned-fish range is a place to compare formats, including own-label spring-water chunks.
Its own-label spring-water chunks include a listed 4 × 145g multipack for planning several portions.
Its own-label spring-water chunks include a listed 4 × 145g multipack.
Relevant if a single 160g spring-water chunk tin fits your portion plan.

A no-drain pack avoids draining tuna at the picnic site; Asda describes its listed John West No Drain spring-water chunks as ready to eat. If you are making sandwiches or salad at home, standard spring-water chunks are another option, provided you have a way to handle the liquid before packing.
Choose by whether you want the packing liquid in the finished dish, then compare the exact nutrition labels. Princes lists 171 kcal and 6.5g fat per 100g for its drained sunflower-oil tuna, compared with 122 kcal and 1g fat per 100g for its drained spring-water product; those values are specific to those variants.
Follow the storage instruction on that pack. For its listed spring-water chunks, Sainsbury’s says to transfer unused contents to a non-metallic container, refrigerate and use within one day. Check the time stated on other products rather than applying that instruction to every tin.
For pregnancy, the NHS advises no more than four cans of tuna or two tuna steaks a week because tuna can contain pollutants including mercury. That limit has a specific pregnancy context; it is not a general serving size for everyone at a picnic.
The listed tuna products identify tuna as fish in their ingredients or allergen information. Check the current label of the precise pack before serving it, particularly when preparing shared picnic food.
