What matters when choosing?
Start with the meals and portions you plan to make, then decide whether ease of preparation or a particular preserving medium changes the pack you need.
| Concern | What to check | Who this matters to |
| Usable quantity |
Count the tins and look for drained weight, rather than treating the weight including liquid as the amount of fish. Princes states 4 x 102g drained for one 4 x 145g spring-water pack. |
I’m preparing food for a group and need to know whether the opened tins will cover the planned portions. About 40% of consumers put usable quantity first. |
| Low-mess preparation |
Confirm that the exact pack is no-drain and check its tin sizes against the portions you intend to serve. |
With little space to drain tins or manage leftovers, I want portions I can open as needed; about 30% of consumers prioritise that convenience. |
| Recipe fit |
Check whether the tuna is packed in spring water, brine or oil, and read the exact variant’s ingredients and nutrition panel. |
If my meal already has a dressing, the preserving medium may change how I prepare it. For about 20% of consumers, recipe fit is the primary concern. |
| Serving restrictions |
Check fish allergen labelling and the instructions for any opened tin; account for NHS tuna guidance when planning repeated servings for someone who is pregnant or trying for a baby. |
Before serving a mixed group, I need to know who can eat the tuna and whether leftovers can be kept as directed. These checks come first for about 10% of consumers. |

Common questions
Should I use tin weight or drained weight to plan festival portions?
Use drained weight where the pack states it, because the weight including liquid is not all fish. For example, Sainsbury’s listing for Princes 4 x 145g spring-water tuna states 4 x 102g drained. Work from the tuna your recipes need, then check how many tins that requires.
How long can I keep an opened tin of tuna?
Follow the exact tin’s instructions and keep opened tuna chilled as directed. Sainsbury’s checked own-label four-pack says to refrigerate and use within one day, whereas its checked Princes four-pack listing says two days. If you cannot meet the storage instructions at a festival, plan to finish a tin when you open it.
Can I serve tinned tuna to someone with a fish allergy?
Tinned tuna contains fish and is not suitable for someone with a fish allergy. Check the current product label, including any precautionary allergen statements, before preparing food for a group.
Does pregnancy guidance affect how much tuna to pack?
Yes, if someone who is pregnant or trying for a baby may eat tuna across several meals. NHS guidance says they should have no more than four cans of tuna or two tuna steaks in a week because tuna contains more mercury than other fish. Plan around that person’s total weekly intake, not just one festival meal.
