Family picnic planners
If you are preparing several sandwiches, wraps or a shared salad, compare can sizes and drained quantities before deciding how many cans to take.
Who is this for?
Picnic makers choosing a recipe
If the tuna will be mixed with dressing or other ingredients, choose its packing medium deliberately and read the ingredients and nutrition panel for that variant.
Hosts preparing food ahead
If sandwiches or salads will travel to an outdoor meal, plan how to keep them chilled and check fish-allergy needs before sharing.
What matters when buying?
Start with the quantity your menu needs, then choose the packing medium and make a plan for serving prepared food outdoors.
| Concern | What to check | Who this matters to |
|---|---|---|
| Quantity for sharing | Check the number and size of cans, then compare drained quantity for the portions you plan to make. | If I am making several fillings, I need enough tuna without opening more cans than I can use. About 40% of consumers put shared quantity first. |
| Packing medium | Check whether the tuna is in spring water, brine or oil, and read that variant’s ingredients and nutrition panel. | When I am mixing tuna with a dressing or other ingredients, I want the packing medium to suit the finished filling. For about 30% of consumers, recipe fit is the primary need. |
| Outdoor serving | Plan space in a cool bag or cool box with ice or frozen gel packs; check fish-allergy needs. | If I prepare sandwiches or salad before leaving, I need a way to keep them chilled and share them safely. Picnic serving and dietary safeguards come first for about 30% of consumers. |
Picnic shopping pitfalls
-
Buying by can count alone
Four-can packs can contain different can sizes. Can count therefore does not tell you how much tuna your recipe will have once it is drained.
Compare the stated quantity and drained weight, then choose a pack that fits the planned portions and the leftovers you can chill.
-
Treating every packing liquid alike
Spring water, brine and oil are different ingredients. John West lists tuna, water and salt for its brine four-pack, so its nutrition panel should not be applied to a water- or oil-packed variant.
Choose the medium for the filling you are making and read the label on the exact pack.
-
Leaving prepared tuna food out
Sandwiches and salads made with opened tuna need a chilling plan for a summer picnic. The Food Standards Agency advises keeping foods normally stored in the fridge cool in a cool bag or cool box with ice or frozen gel packs.
Take out what you need for serving and return the remaining food to the cool bag or box promptly.
You may need to carry a cool bag or cool box and ice or frozen gel packs.
-
Overlooking fish when sharing food
Tuna contains fish, an allergen that matters to anyone with a fish allergy.
Check the can and any added ingredients, prevent cross-contact during preparation and identify tuna dishes when sharing.

Frequently asked questions
What pack size should I choose for a family tuna picnic?
A 4 x 145g multipack is a starting point for several sandwiches, wraps or portions of a shared salad. Work out how much your recipe needs, then compare can size and drained quantity; Tesco has listed both 4 x 145g multipacks and smaller formats.
How should I carry tuna sandwiches or salad to a picnic?
Keep the prepared food chilled in a cool bag or cool box with ice or frozen gel packs. The Food Standards Agency advises keeping foods normally stored in the fridge cool at a picnic, so plan the space and cooling equipment before making the filling.
What should I do with tuna left after opening a can?
Follow the storage instructions on the exact pack. Joybuy’s listing for Princes Tuna Chunks in Spring Water 4 x 145g says to transfer opened tuna to a sealed container, refrigerate it and use it within two days; check other variants’ own instructions rather than assuming they are identical.
Does a tuna multipack need extra consideration during pregnancy?
Yes, if someone who is pregnant or trying for a baby will eat it. NHS guidance limits tuna to no more than four cans a week or two tuna steaks a week for those groups; plan that person’s portions with their intake across the week in mind, rather than treating the number of cans in a multipack as a serving recommendation.
