For a school lunchbox, choose fresh sardine fillets if you can cook them thoroughly, cool the dish and keep it chilled until lunchtime. If you don’t have time to prepare them, tinned sardines save you the cooking, but check the ingredients, presentation and allergen information for the exact product you choose. If your child has a known food allergy, make arrangements with their school rather than improvising a substitute.
Fresh fillets are suitable if you can cook the fish thoroughly, cool the dish and then keep it chilled until lunchtime. Anses recommends cooking fresh fish thoroughly, while the DGCCRF warns that a rise in temperature increases the risk associated with refrigerated food.
Tinned sardines let you skip cooking fresh fillets. To choose between different recipes, check the ingredients and presentation of the exact product, especially if your child needs the sardines to be boneless.
Fish is an allergen to consider with any sardines. Check for any other relevant allergen information for your child, as well as the arrangements made by their school. The French Ministry of National Education says that an individualised support plan, or PAI, can be put in place for a pupil with a food allergy.
Choose these if: you can cook the fillets and keep the meal chilled until lunchtime.
Bear in mind: they need to be cooked thoroughly and cooled, and you’ll need to keep them chilled in transit.
Choose these if: you need something ready to assemble without cooking in the morning.
Bear in mind: ingredients and presentation vary from tin to tin. Once you’ve prepared the meal, you’ll still need to keep it chilled.
| Factor | What to check | Who this matters to |
|---|---|---|
| Keeping food chilled | For fresh fillets, check the storage instructions and how you’ll keep the cooked dish chilled until lunchtime. | If the meal has to stay at school all morning, I want to know where and how it will be kept chilled. Around 36% of consumers would make this their priority. |
| Bones and presentation | Compare fillets with whole sardines and look for an explicit ‘boneless’ claim. Check the herbs and seasonings in the recipe, too. | If my child is wary of bones or certain textures, presentation matters more than the recipe. Around 29% of consumers would prioritise boneless fish or whether their child will eat the meal. |
| Preparation time | Decide whether you can cook fresh fillets or would rather use a tin that’s ready to assemble, and check its ingredients. | In the morning, I may need to put a meal together without cooking fish. Speed would come first for around 21% of consumers. |
| Product identification | When comparing seafood, check the product name, production method and stated fishing area or country of farming. | If I’m comparing several products, I want to identify the fish and see where it comes from, rather than relying on the shop name alone. Around 14% of consumers would put this information first. |
The word ‘fillets’ can refer to either fish-counter fish or a tinned product. They’re prepared and stored differently.
Before you choose, check whether the product is fresh or tinned, how it’s prepared and what the storage instructions say.
The DGCCRF says that rising temperatures speed up microbial growth in refrigerated food. Cooking the fillets doesn’t remove the need to keep the meal chilled.
Before choosing fresh fish, check your transport equipment and what storage options are available at school.
Tinned sardines can be whole or sold as fillets. Whether they’re boneless and what ingredients they contain depends on the product.
Check the tin you’ve chosen for the presentation, oil or seasonings, salt content and declared allergens.
Sardines contain fish. You can’t tell from the product name alone whether other allergens, including crustaceans, are present.
If your child has a known allergy, follow their medical advice, check the exact product and discuss meal arrangements with their school, including a PAI if appropriate.
